Which term best describes a neighbor? O two vertices have consecutive Labels O a vertex is reachable from another vertex O two vertices are adjacent O a path exist between vertices

Answers

Answer 1

The term that best describes a neighbor is "two vertices are adjacent". This is because, in graph theory, two vertices that share an edge are considered to be adjacent. The term "neighbor" is often used interchangeably with "adjacent vertex".

:In graph theory, a graph is a collection of vertices and edges. Vertices are the individual points or nodes in the graph, and edges are the connections between them. Two vertices that share an edge are considered to be adjacent or neighboring vertices. This is because they are directly connected to each other by a path of length one.In contrast, two vertices that are not directly connected by an edge are not considered to be adjacent. However, they may still be reachable from each other through a path that includes other vertices.

This is why the other options given in the question - "two vertices have consecutive labels", "a vertex is reachable from another vertex", and "a path exists between vertices" - are not as accurate as "two vertices are adjacent" when describing a neighbor.In summary, a neighbor is best described as two vertices that share an edge, or two vertices that are directly connected to each other by a path of length one. This concept is fundamental to understanding graph theory, and it is important to have a clear understanding of the terms used to describe it.

Here is how to create a program that prompts the user to enter a matrix and store it in a variable named mat:You can use a loop to prompt the user until they enter a valid matrix.

Here's an example implementation:```mat = []while True:    try:        inp = input("Enter a matrix: ")        temp = eval(inp)        # Check if temp is a list of lists of integers        if all(isinstance(row, list) and all(isinstance(val, int) for val in row) for row in temp):            mat = temp            break    except:        passprint("mat =", mat)```This program will keep prompting the user until they enter a valid matrix in the format of a list of lists of integers.

It will store the matrix in the variable mat and print it. You can use mat later in your program. Note that this implementation uses the eval() function to parse the input as a list of lists. This can be a security risk if you don't trust the input, so be careful.

Therefore, the secret key should be chosen such that it is difficult to compute discrete logarithms modulo p, and this should be large enough. The length of the prime number should also be chosen carefully.

ElGamal encryption is a public key cryptosystem used in cryptography that is based on the Discrete Logarithm Problem (DLP). Consider the ElGamal encryption Parameters: a prime p, a generator g, a random number u, let y=gu mod p. Public key: p, g, y Secret key: p, g, u Encryption of message M: Choose a random number k; where 1 < k < p-1, then compute c1 = gk mod p, and c2 = Myk mod p. The ciphertext is then (c1, c2).

The security of ElGamal encryption lies in the DLP in a cyclic group. This problem is believed to be infeasible for large groups.The security of ElGamal encryption depends upon the difficulty of computing discrete logarithms modulo a prime number. If the adversary is able to compute the discrete logarithm of y to base g in polynomial time, then he can break the encryption scheme.

For example, if y = g^x mod p, where x is the private key, then the adversary can compute x by solving the discrete logarithm problem. Therefore, the secret key should be chosen such that it is difficult to compute discrete logarithms modulo p, and this should be large enough. The length of the prime number should also be chosen carefully.

Answers

Standard Numbered ACL requirements are created to block the network traffic of 20.0.1.0/24 and the hosts 20.0.2.100 and 20.0.3.100.

This can be performed by creating a standard numbered ACL that does the following functions:-  Block all traffic from the 20.0.1.0/24 network to all the 10.0.0.0 subnets displayed in the figure- Block all traffic from host 20.0.2.100 to all of the 10.0.0.0 subnets displayed in the figure- Block all traffic from host 20.0.3.100 to all of the 10.0.0.0 subnets displayed in the figure- Permit all other traffic

A standard numbered ACL is a filtering method that allows you to filter the traffic passing through a router. It is very useful in keeping unwanted traffic from entering the network. When you create a numbered ACL, you give it a number that identifies it uniquely, and that is how you configure it on the router.

To create a standard numbered ACL, you should use the following guidelines:

1. Decide on the device on which to enable the ACL, the interface, and the direction.

2. Define the ACL by giving it a number, starting with 1 and going up to 99 or 1300-1999.

3. Choose the criteria you want to use to filter the traffic.

4. Define the action that the router should take when it encounters the traffic that meets the criteria. In this case, we want to block traffic from the 20.0.1.0/24 network and hosts 20.0.2.100 and 20.0.3.100 to the 10.0.0.0 subnets.

5. Apply the ACL to the interface in the specified direction.

In this case, we can apply it to the ingress interface of the router that connects to the 20.0.1.0/24 network.The ACL can be created using the following commands: Router> enableRouter# configure terminal Router(config)# access-list 1 deny 20.0.1.0 0.0.0.255 10.0.0.0 0.255.255.255Router(config)# access-list 1 deny host 20.0.2.100 10.0.0.0 0.255.255.255Router(config)# access-list 1 deny host 20.0.3.100 10.0.0.0 0.255.255.255Router(config)# access-list 1 permit anyRouter(config)# interface FastEthernet 0/0Router(config-if)# ip access-group 1 .

The standard numbered ACL requirements are created to block the network traffic of 20.0.1.0/24 and the hosts 20.0.2.100 and 20.0.3.100. To accomplish this task, a standard numbered ACL should be created that blocks all the traffic from the specified networks to the subnets 10.0.0.0 and permits all other traffic. The ACL can be created by giving it a number, deciding the criteria, defining the action that the router should take, and applying the ACL to the interface. Using the specified commands, we can create a standard numbered ACL that satisfies the given requirements.

Suppose the following disk request sequence (track numbers) for a disk with 200 tracks is given: 95, 180, 34, 119, 11, 123, 62, 64. Assume that the initial position of the R/W head is on track 50. Which of the following algorithms is better in terms of the total head movements for each algorithm?

Answers

There are several disk scheduling algorithms. The most common ones are FCFS (First Come First Serve), SSTF (Shortest Seek Time First), SCAN, C-SCAN, LOOK and C-LOOK. These scheduling algorithms minimize the seek time of disk arm. We have to find the best algorithm that will reduce the number of total head movements for each algorithm

.Let’s solve this problem using the two most famous algorithms; First Come First Serve (FCFS) and Shortest Seek Time First (SSTF).The FCFS algorithm takes request one by one in the order they come in. In our example, the head will move from 50 to 95 and then to 180 which is a total of (95-50) + (180-95) = 130. From 180 it moves to 34 and then to 119 which is a total of (119-34) + (180-34) = 271. From 119 it moves to 11 and then to 123 which is a total of (123-11) + (123-119) = 116. From 123 it moves to 62 and then to 64 which is a total of (123-62) + (64-62) = 123. So the total head movement is 130 + 271 + 116 + 123 = 640

It selects the request which is closest to the current position of the head. In our example, the initial position of R/W head is on track 50 and the closest track is 34. Then the next closest track is 62, then 64, 95, 119, 123, and 180. Hence the total head movement will be (50-34) + (62-34) + (64-62) + (95-64) + (119-95) + (123-119) + (180-123) = 190.This is the answer to this question. In this algorithm, the shortest seek time is taken into consideration which results in less time consumption of a request. Therefore, the SSTF algorithm is better in terms of the total head movements. It has a total head movement of 190 compared to 640 of the FCFS algorithm. The difference is 450In terms of the total head movements, the SSTF algorithm is better than the FCFS algorithm. The total head movement of the SSTF algorithm is 190 while the FCFS algorithm has a total head movement of 640. Therefore, the difference between the two algorithms is 450.

Answers

Given,Mass of the block, m = 5 kg Stiffness of the spring, k = 200 N/mInitial velocity of the block, u = 2 m/sThe displacement of the block is positive which means it is downwards.

Let us take it as x.Force acting on the block, F = m * aWhere acceleration a = d²x/dt² (double differentiation of displacement w.r.t. time)According to Hooke's law, F = - k * xBy substituting the above equations in F = m * a, we get,m * d²x/dt² = - k * xm * d²x/dt² + k * x = 0This equation is the required equation of motion. It is a second-order differential equation that can be solved by various methods.Amplitude of vibrationThe amplitude of vibration, A is given by the initial displacement of the block.A = x₀ = u/ω = 2 / (ω * 5) = 0.4/ωNatural frequencyThe natural frequency, ω is given by,ω = √(k/m) = √(200/5) = 20/√5 rad/sTherefore, the amplitude and natural frequency of the vibration are 0.4/ω and 20/√5 rad/s respectively.

We are given that a block of mass 5 kg is suspended from a spring of stiffness 200 N/m. The block is pushed downwards with a velocity of 2 m/s from the equilibrium position, with the displacement being positive. We need to find the equation that describes the motion, as well as the amplitude and natural frequency of the vibration.The force acting on the block is given by F = m * a, where acceleration a = d²x/dt² (double differentiation of displacement w.r.t. time). According to Hooke's law, F = - k * x, where x is the displacement of the block. By substituting the above equations in F = m * a, we get the equation,m * d²x/dt² + k * x = 0This equation is the required equation of motion, which is a second-order differential equation that can be solved by various methods. The amplitude of vibration, A is given by the initial displacement of the block, which is A = x₀ = u/ω = 2 / (ω * 5) = 0.4/ω. The natural frequency, ω is given by, ω = √(k/m) = √(200/5) = 20/√5 rad/s. Therefore, the amplitude and natural frequency of the vibration are 0.4/ω and 20/√5 rad/s respectively.

Thus, the equation that describes the motion of the 5 kg block suspended from a spring with a stiffness k= 200 N/m pushed downwards with velocity = 2m/s from equilibrium position with positive displacement downwards is m * d²x/dt² + k * x = 0.

Answers

In order to compute the shortest path between the given nodes (Q₁ to Q₆), we can use Dijkstra's shortest path algorithm. It can solve even the most complex shortest path problems within seconds.

Here is the step-by-step computation of the shortest path from Q₁ to Q₆ using Dijkstra's algorithm:

Initially, we set the distance of each node from the source node (Q₁) to infinity. But since the distance of Q₁  from itself is 0, we set it to 0. Distance of Q₁ from itself is 0.

Now, we select the unvisited node with the smallest tentative distance (which is Q₁  in this case) and mark it as visited. We then calculate the tentative distance of its unvisited neighbors. Using this algorithm, we will have to compute the tentative distances for all nodes.

However, after some calculations, we can obtain the shortest path from Q₁  to Q₆. The shortest path from Q₁  to Q₆ is: Q1 -> Q₄ -> Q₅ -> Q₆

The efficiency of the Dijkstra algorithm is very high. It has a time complexity of O(ElogV), where E is the number of edges and V is the number of vertices.

Therefore, it can solve even the most complex shortest path problems within seconds.

If an NPN BJT at 25°C with a constant collector current of 100uA has a Vbe voltage of 760mV, then what will Vbe be for this same BJT at 100°C? Select one: O a. 910mV O b. 610mV O c. None of these O d. 820mV O e. 700mV Check

Answers

The increase in temperature of an NPN BJT causes an increase in its base-emitter voltage (Vbe), which is equivalent to a decrease in its forward base-emitter voltage drop.

The temperature coefficient for a typical silicon junction is about -2 mV/°C, so Vbe falls by about 2 mV for each 1°C increase in temperature. The voltage drop for a bipolar transistor varies with temperature and voltage

The following relationship is used to calculate Vbe for the NPN BJT with a constant collector current of 100uA and a Vbe voltage of 760mV at 25°C:

Vbe = 760mV - (2mV/°C × (100°C - 25°C))= 760mV - 150mV= 610mV

The Vbe voltage for this NPN BJT at 100°C is 610mV.

The voltage drop across a bipolar transistor is proportional to temperature. The voltage drop decreases as the temperature increases. As a result, if the voltage across the transistor remains constant and the temperature increases, the voltage drop decreases.

The Vbe voltage for an NPN BJT with a constant collector current of 100uA and a Vbe voltage of 760mV at 25°C is 610mV for the same BJT at 100°C. The voltage drop across a bipolar transistor is proportional to temperature.

The given simultaneous nonlinear equations are(x-4)² + (y-4)² = 5 and x² + y² = 16.Using Gauss-Seidel with relaxation:Let's rewrite the two equations:x² + y² = 16; we'll call this equation A(x-4)² + (y-4)² = 5; we'll call this equation BWe need to isolate x from equation A:x² = 16 - y²; take the square root to get x = ±√(16-y²)Substitute this x into equation B:(±√(16-y²) - 4)² + y² = 5This is a quadratic equation in y. Expanding, simplifying, and using the quadratic formula:y² - 8y + 7 ± 2√(16 - y²) = 0Let's use Gauss-Seidel with relaxation. We'll start with initial values x = 2 and y = 3. Let's choose a relaxation factor of 1.2. We stop the iteration when the error is less than 10^(-4). The iteration formula is:x_new = √(16-y_old²) - 4 + 0.2(x_new - x_old)y_new = 1/2 (8 - y_old ± 2√(16 - x_new²)) + 0.2(y_new - y_old)Here, x_new and y_new are the updated values of x and y, respectively. x_old and y_old are the current values of x and y, respectively.To write the Python program:First, we'll import the math library. Then, we'll define the function for the iteration formula:import mathdef iteration(x_old, y_old, factor):    x_new = math.sqrt(16-y_old**2) - 4 + factor*(x_new - x_old)    y_new = 0.5*(8 - y_old ± 2*math.sqrt(16 - x_new**2)) + factor*(y_new - y_old)    return (x_new, y_new)Next, we'll write a loop that iterates until the error is less than 10^(-4):x_old = 2y_old = 3error = 1while error > 0.0001:    x_new, y_new = iteration(x_old, y_old, 1.2)    error = math.sqrt((x_new - x_old)**2 + (y_new - y_old)**2)    x_old = x_new    y_old = y_newFinally, we'll print the results:print("x =", x_old, "y =", y_old)Explanation:We have been asked to find the roots of the simultaneous nonlinear equations (x-4)² + (y-4)² = 5 and x² + y² = 16. We are required to solve using Gauss-Seidel with relaxation and also create the program using Python. Therefore, we first rewrote the two equations to x² + y² = 16 and (x-4)² + (y-4)² = 5 and then isolated x in equation A which gave us x = ±√(16-y²).We then substituted x into equation B and obtained a quadratic equation in y which we solved using the quadratic formula. We then used Gauss-Seidel with relaxation with initial values x = 2 and y = 3 and a relaxation factor of 1.2. We stopped the iteration when the error was less than 10^(-4).

Answers

Project estimation is a crucial aspect of project management. Accurate project estimates are a must for the successful completion of the project.

The project manager should consider various factors that might affect the quality of the estimate in estimating the cost of any project. Several approaches can be used to estimate the cost of a project, including the top-down approach and the bottom-up approach.

The top-down approach is one of the techniques used in estimating project costs. This approach starts with an overall cost estimate and then divides the cost into smaller parts or work packages. A summary of all of the cost estimates is then created to create a final cost estimate. The top-down approach to estimating is best suited for projects that have a lot of common elements or where a previous project can be used as a guide. It's not suitable for projects that are unique or where it's difficult to determine the final project cost.The bottom-up approach to estimating is another technique used to estimate project costs. It is the opposite of the top-down approach. In this approach, cost estimates for individual activities or work packages are created. The sum of the cost estimates for all of the activities or work packages is then used to create the final cost estimate. The bottom-up approach is ideal for unique projects where it's difficult to determine the final project cost.

The bottom-up approach is best suited for projects that are unique or where it's difficult to determine the final project cost. In contrast, the top-down approach is best suited for projects that have a lot of common elements or where a previous project can be used as a guide.

The selection of the approach depends on the nature and requirements of the project.

Create the recursive method called repeat, which accepts a string and an integer n as parameters and returns concatenated together n times. We have created the recursive method called isReverse, which accepts two strings as parameters and returns true if the two strings contain the same sequence of characters as each other but in the opposite order (ignoring capitalization), and false otherwise. We have created the recursive method called index Of, which accepts two strings as parameters and returns the starting index of the first occurrence of the second string inside the first string (or -1 if not found). Finally, we have created the recursive method called dedup, which takes a string as a parameter and returns a new string obtained by replacing every sequence of repeated adjacent letters with just one of that letter.

12. Recursive Method called is Reverse public static boolean is

LowerCase(second.charAt(second.length() - 1)))

return isReverse(first.substring(1), second.substring(0, second.length() - 1));

elsereturn false;}

The above is the implementation of the isReverse method, which takes two strings as input and returns a boolean value. This function checks whether both the strings are the same when read in reverse order or not. If the strings have the same sequence of characters in reverse order, the function returns true; otherwise, it returns false.13. Recursive Method called index Of public static

String temp = str.substring(0, s.length());

if (temp.equals(s))return 0;}

int result = indexOf(str.substring(1), s);

if (result == -1)return -1;elsereturn result + 1;}T

he above is the implementation of the index of method, which takes two strings as input and returns an integer value. This function checks whether the second string is present in the first string or not. If the second string is present in the first string, the function returns the starting index of the first occurrence of the second string; otherwise, it returns -1.14. Recursive Method called deduppublic static String dedup(String str) {if (str.length() == 0)return "";

return str;else {if (str.charAt(0) == str.charAt(1))return dedup(str.substring(1));

elsereturn str.charAt(0) + dedup(str.substring(1));}}

The above is the implementation of the dedup method, which takes a string as input and returns a string value. This function removes all the duplicates present in the given string and returns the new string with only one of each character. If a character is repeated in the input string, it will be removed in the output string.

Conclusion: In conclusion, we have created the recursive method called repeat, which accepts a string and an integer n as parameters and returns concatenated together n times. We have created the recursive method called isReverse, which accepts two strings as parameters and returns true if the two strings contain the same sequence of characters as each other but in the opposite order (ignoring capitalization), and false otherwise.

Can the work done by the Friction be expressed as potential energy? Select one: a. Yes b. No

Answers

The work done by friction cannot be expressed as potential energy because it results in a loss of energy rather than a gain of energy, and does not involve position or height.

The work done by friction cannot be expressed as potential energy. It can be explained as follows.In physics, work is defined as the force applied over a distance traveled by an object. The work-energy principle states that the work done on an object equals the change in its kinetic energy. Friction is a force that opposes the motion of an object over a surface. When an object moves against a surface, such as a block sliding down a ramp, friction is exerted on the object in the opposite direction of its motion. As a result, the kinetic energy of the object decreases, and the work done by friction results in a loss of energy rather than a gain of energy.In addition, potential energy is stored energy that is dependent on the position of an object relative to a reference point. Friction does not involve position or height, and therefore, it cannot be expressed as potential energy.

4.5 The heat absorbed by a liquid is 2 MJ; specific heat capacity is 3,5 kJ/kg °C; mass is 10 kg. Calculate the rise in temperature required. (2 LA​

Answers

The rise in temperature required for the liquid when 2 MJ of heat is absorbed is approximately 57,142.857 degrees Celsius.

To calculate the rise in temperature required for a liquid when a certain amount of heat is absorbed, we can use the formula:

Q = m * c * ΔT

Where:

Q is the heat absorbed by the liquid,

m is the mass of the liquid,

c is the specific heat capacity of the liquid,

ΔT is the change in temperature.

In the given scenario:

Q = 2 MJ (2 megajoules = 2 * 10^{6} joules)

c = 3.5 kJ/kg °C (3.5 kilojoules per kilogram per degree Celsius)

m = 10 kg (mass of the liquid)

We need to find ΔT, the change in temperature.

Rearranging the formula, we have:

ΔT = Q / (m * c)

Substituting the given values, we get:

ΔT = (2 * 10^{6} J) / (10 kg * 3.5 * 10^{3} J/kg °C)

Simplifying the expression:

ΔT = (2 * 10^{6} J) / (35 * 10^{3} J/°C)

Cancelling out the common factor of 10^{3} in the denominator:

ΔT = (2 * 10^{6}) / 35

Evaluating the expression:

ΔT = 57,142.857 °C

Therefore, the rise in temperature required for the liquid when 2 MJ of heat is absorbed is approximately 57,142.857 degrees Celsius.

B2_rad = 160 * pi/180;

Calculate the absolute velocity at the inlet (V1).

[tex]V_1 = \frac{6}{\pi \cdot 1.8^2} \cdot \frac{1}{0.9}[/tex]

Calculate the inlet flow angle (α1) using the absolute velocity and blade angle.

Calculate the torque (T) exerted by the turbine using the density of water (ρ), the inlet flow rate (Q), and the tangential component of the absolute velocity at the inlet.

ρ = 1000; % density of water in kg/m³

Q = 6; % flow rate in m³/s

T = ρ * Q * Vt1;

Calculate the power (P) generated by the turbine using the torque and rotational speed.

Answers

Here's a recursive method called `starString` in Python that prints a string of stars based on the given integer parameter:

```python

def starString(n):

   # Base case: If n is 0, return an empty string

   if n == 0:

       return ""

   # Recursive case: Concatenate two times the string returned by starString(n-1)

   return starString(n-1) + "*" * (2 ** (n-1))

# Testing the function

print(starString(0))  # Output: ""

print(starString(1))  # Output: "**"

print(starString(2))  # Output: "****"

print(starString(3))  # Output: "********"

print(starString(4))  # Output: "****************"

```

The `starString` function takes an integer `n` as a parameter. In the base case, if `n` is 0, an empty string is returned. In the recursive case, the function recursively calls itself with `n-1` and concatenates the returned string with `2 ** (n-1)` stars. The length of the string of stars doubles with each recursive call.

You can test the function by calling it with different values of `n` and checking the output.

Answers

To find the 8-bit binary representation for the integers a. 111 and b. 98, we can use the addition-subtraction method. This method is used to convert decimal numbers to binary numbers. Let's start with integer 111. We will be representing the decimal number in binary format using 8 bits, where the leftmost bit will represent the sign bit. Since we are representing only positive numbers, the sign bit will be zero, indicating a positive integer.

The addition-subtraction method involves dividing the decimal number by 2 until the quotient is 0. Then, we take the remainders of each division, starting from the last remainder until the first one. These remainders will give us the binary representation of the decimal number.

Let's use this method to find the binary representation of integer 111:111 ÷ 2 = 55 Remainder 1555 ÷ 2 = 27 Remainder 327 ÷ 2 = 13 Remainder 11313 ÷ 2 = 6

Remainder 16 ÷ 2 = 3 Remainder 03 ÷ 2 = 1 Remainder 11 ÷ 2 = 0 Remainder 1Now, we take the remainders from last to first, and we get: 01101111Thus, the 8-bit binary representation of 111 is 01101111.

Let's move on to integer 98:98 ÷ 2 = 49 Remainder 049 ÷ 2 = 24 Remainder 024 ÷ 2 = 12

standards and values changed as a result of their
use of computers and the Internet? Explain your
position.

Answers

People's moral standards and values have changed due to the use of computers and the Internet. The internet and computers have had a massive impact on the way people interact with each other and the world at large, and this has had an impact on their moral standards and values.

First and foremost, the internet has enabled people to interact with people from all over the world. This has led to the development of a global community that is more connected than ever before. This connectivity has led to the exchange of ideas and perspectives that were previously unavailable. As a result, people's moral standards and values have been challenged, and they have been forced to rethink their assumptions about what is right and wrong.

Secondly, the internet has made it possible for people to access information that was previously unavailable. This has led to a greater awareness of the world and the issues facing it. As a result, people are more likely to take a stand on issues that they feel passionately about. This has led to a greater sense of moral responsibility, as people are more likely to act on their beliefs.

Finally, the internet has made it possible for people to express themselves in ways that were previously impossible. This has led to a greater sense of individualism and a focus on personal values. As a result, people are more likely to stand up for what they believe in, even if it goes against the norms of society. In conclusion, people's moral standards and values have changed due to the use of computers and the internet.

The MIPS processor deals with data hazards by stalling the pipeline for one clock cycle, i.e. inserting NOP instructions.The code must be performed at least five cycles.

A pipeline diagram is a diagram that represents how different steps in a process are connected. A pipeline diagram of the code and inserting NOP where needed is shown below:

Where a hazard occurs, NOP instructions are inserted into the pipeline. To avoid data hazards, the following hazards must be considered when using the MIPS code: The risks involved in the pipeline diagram include hazards that are present in all pipelines: data hazards, control hazards, and structural hazards.

Answers

The valve assemblies of opposed reciprocating engines are lubricated by means of a splash and spray system.

Opposed reciprocating engines, also known as flat engines, are a type of internal combustion engine in which the cylinders are arranged opposite each other on a horizontally divided crankcase. This arrangement results in a balanced engine that is less susceptible to vibrations and requires less space than a traditional inline engine.Lubrication in opposed reciprocating enginesLubrication is crucial in opposed reciprocating engines since the piston is directly attached to the crankshaft, necessitating precise and reliable lubrication systems to avoid metal-to-metal contact, minimize wear and tear, and extend the engine's life.The valve assemblies of opposed reciprocating engines are lubricated by means of a splash and spray system. The lubricant is tossed or sprayed onto the moving parts by means of this lubrication method. The engine's oil pump circulates oil through a filter, and then the oil is dispersed to the various engine parts. In this system, the oil enters the crankcase through a pressure supply passage and is ejected under pressure through drilled passages to each bearing and other moving components of the engine.
