For the 'lw' instruction, what would be the chosen path for the 'MemtoReg' mux? Your answer: O 1 0 O X: don't care
In MIPS (Microprocessor without Interlocked Pipeline Stages), the “lw” instruction refers to the Load Word instruction. The chosen path for the "MemtoReg" MUX in this instruction would be the “1” path. This path is selected to transfer the content of the memory location, which is being accessed by the “lw” instruction, to the register file.
The value present in the memory location is loaded into a register that is specified in the instruction. Additionally, the content of the register file can also be supplied to the “MemtoReg” MUX by the “0” path. This is done when the instruction is not a “lw” instruction and the immediate value present in the instruction is loaded into the register. The path can also be selected as “X”, which refers to the “don’t care” state. When “X” is selected, the MUX can receive any input value. Here, the chosen path for the “MemtoReg” MUX in the “lw” instruction is “1”. The "lw" instruction is used to load the word present in the memory location into the specified register. The "MemtoReg" MUX chooses the path "1" to transfer the memory location content to the register.

A channel is trapezoidal in shape with a side slope of 1 : 1.5, a bed width of 5.0 m and a bottom slope of 0.0025. The construction of the barrage structure causes an increase in the water depth upstream of the barrage to 7.0 m at a flood discharge of 75.0 m3/sec. If the Manning roughness number n = 0.020. Calculate and describe the water level profile that occurs, by using both Standard Step Method, and Direct Step Method.
Calculation of the water level profile that occurs, using both Standard Step Method, and Direct Step Method. Water level profile is a graphical representation of the water levels along the longitudinal direction of a channel.
The design of a channel is very important since it plays an important role in conveying water. Channels must be designed so that they can safely convey water without overflowing and causing floods. The Standard Step Method and Direct Step Method are two methods that can be used to calculate the water level profile that occurs in a channel. These methods use different mathematical formulas to calculate the water level profile that occurs. The Standard Step Method uses a mathematical formula that considers the water level at each step of the channel, while the Direct Step Method uses a mathematical formula that considers the water level at the end of the channel. The Manning roughness number, bed width, bottom slope, and side slope are some of the factors that are considered in calculating the water level profile.Conclusion: The water level profile that occurs in a trapezoidal shaped channel with a side slope of 1:1.5, a bed width of 5.0 m, and a bottom slope of 0.0025, was calculated using both Standard Step Method, and Direct Step Method. The water depth upstream of the barrage increased to 7.0 m at a flood discharge of 75.0 m³/sec. The Manning roughness number used for calculation is n = 0.020. The Standard Step Method and Direct Step Method are two methods used to calculate the water level profile that occurs in a channel.
The Standard Step Method considers the water level at each step of the channel, while the Direct Step Method considers the water level at the end of the channel.

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
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.

int score[3] (60, 70, 80); Using the above declaration, the cout statement below will display all the items in the array score. cout << score; True False Assuming teamScore is an array of int values and count is an int variable, both the following statements will do the same action. 1. cout << teamScore[count] << endl; 2. cout <<"(teamScore + count) << endl; True False
Problem 6: The given statement is true.
Problem 7: The given statement is false.
Problem 6:
The count statement will not display all the items in the array score correctly.
This is because the name of the array score points to the memory address of its first element. Therefore, when we use cout to output the array name, it will display the memory address of the first element in the array, which is not what we wanted.
To display all the items in the array score, we need to use a loop to iterate through each element in the array and print them out individually. For example:
for (int i = 0; i < 3; i++) { cout << score[i] << " "; }
This will print out all three elements in the array: 60 70 80.
Hence the statement is true.
Problem 7:
The two statements will not do the same action.
The first statement cout << teamScore[count] << endl; will output the value of the element in the teamScore array at the index specified by the count variable.
The second statement cout<<"(teamScore + count) << endl;
Will output the memory address of the element in the teamScore array at the index specified by the count variable.
To output the value of the element in the teamScore array using pointer arithmetic, we need to dereference the pointer first by using the operator.
The correct statement should be:
cout << *(team score + count) << endl;
This will output the value of the element in the team Score array at the index specified by the count variable, just like the first statement.
Thus the statement is false.

A three phase load of 1MW at a p.f of 0.8 lagg is supplied by a 30KV line of resistance 25 ohm and inductive reactance 12ohm/phase. The voltage across the load is 10KV. A 30/10 KV transformer steps down the voltage at the receiving end. The equivalent resistance and reactance of the transformer as reffered to 10K side are 0.8 ohm and 0.25 respectively. Find the sending end voltage and regulation.
Given,Power rating (P) = 1 MWPower factor (pf) = 0.8 laggingLine Voltage (VL) = 30 kV, Resistance (R) = 25 Ω/phaseInductive Reactance (XL) = 12 Ω/phaseVoltage across the load (VL') = 10 kV.
Equivalent resistance as referred to 10 kV side (R2') = 0.8 ΩEquivalent inductive reactance as referred to 10 kV side (X2') = 0.25 Ω.
The primary voltage of the transformer is equal to the voltage across the line. Hence the sending end voltage of the transmission line is also 30 kV.
Steps to find out the sending end voltage and regulation:
The transformer and transmission line are given in per-phase. So, we need to convert the power rating into per-phase values in order to calculate voltage and regulation.Per-phase power = Power rating / number of phases= 1 MW / 3= 0.33 MW.
Per-phase apparent power (S) = per-phase power / power factor= 0.33 MW / 0.8= 0.41 MVAApparent power (S) = VL IL...[1]Where,IL = Line CurrentZ = Impedance of the lineLet's calculate the impedance of the line,Z = R + jXL= 25 + j12= 25 + j12 Ω...[2].
From equation [1],[tex]IL = S / VLIL = 0.41 × 10^6 / (30 × 10^3)IL = 13.67 A.[/tex]
From equation [2], we get the impedance of the line as 25 + j12 Ω.Now, the voltage drop in the line,ΔVL = ILZ= 13.67 × (25 + j12)= 341.7 - j164.1VSo, the receiving end voltage [tex](VL') = VL - ΔVL= 30 kV - (341.7 - j164.1)V= (29658 + j164.1) V.[/tex]
Now, let's calculate the voltage across the transformer secondary side (V2).The transformer's turns ratio = VL / V2Let the turns ratio be k.Now,k = VL / V2V2 = VL / k= 30 / 3= 10 kVNow, the voltage regulation,
Regulation = (V2 - VL') / VL' × 100%...[3]Let's find the current drawn by the load. We know that,S = V I...[4]Where, I = Load Current= S / V= 0.41 × 10^6 / 10 × 10^3= 41 A.
Now, let's calculate the voltage drop across the transformer at full load. V2 = I (R2' + jX2')= 41 × (0.8 + j0.25)= 32.98 + j10.25 VFrom equation [3], the voltage regulation = [tex](V2 - VL') / VL' × 100%= ((32.98 + j10.25) - (29658 + j164.1)) / (29658 + j164.1) × 100%= -99.89%.[/tex]
The sending end voltage is 30 kV.
The sending end voltage is 30 kV and the regulation is -99.89%. The negative value of regulation indicates that the voltage at the receiving end is less than the voltage at the sending end.

Explain the steps involved in the execution of an instruction for a program containing 2 instructions
When a computer executes a program, there are four steps involved in the execution of an instruction for a program containing two instructions.
These steps are as follows:
1. Fetching: The processor fetches the next instruction from memory using the address in the program counter.
2. Decoding: The processor decodes the instruction it just fetched to determine what operation to perform.
3. Executing: The processor executes the instruction by performing the operation specified in the instruction.
4. Storing: The processor stores the results of the instruction in memory or in a register.The four steps involved in the execution of an instruction are called the instruction cycle. The instruction cycle is repeated for each instruction in the program until the program is complete.
Example: Let's say the program has two instructions. The first instruction is to add two numbers, and the second instruction is to store the result in memory. Here are the steps involved in the execution of these two instructions:
1. Fetch the first instruction from memory.
2. Decode the instruction to determine that an addition operation is required.
3. Execute the instruction by adding the two numbers.
4. Store the result of the addition in a register.
5. Fetch the second instruction from memory.

The random samples are then used to calculate the median absolute deviation (MAD) using the mad function. The MAD is a measure of variability, and it is calculated as the median of the absolute deviations from the median. In the case of a normal distribution, the MAD is used as an alternative to the standard deviation when the distribution is not symmetrical. The MAD is also useful when the data has outliers, which can affect the standard deviation. Confidence intervals are a range of values that are used to estimate an unknown parameter, such as the population mean. Confidence intervals are used to give an idea of how much uncertainty there is in a measurement or estimate.

which are true and which are false?
Out of the following expressions, the given expressions are true and which are false : n3 + 800n4 = O(n4) (False)2n6 + 6n9 = O(n10) (True)60n2 + 4n3 + 5n10 = O(n2) (False)
The term O notation defines an upper limit for a function. We use this notation to characterize the rate of growth of a function. When it comes to algorithms, it is frequently utilized to describe the number of basic operations they perform. The following are the explanations behind why the given expressions are true and false: The first expression is n3 + 800n4 = O(n4), which is false because O-notation represents upper bounds. And here, the upper limit is of order n4. But if we see here, the degree of n4 in the expression n3 + 800n4 is greater than the degree of n4 in the expression O(n4), i.e., O(n4) ≡ n4. So, it does not follow the rule of O-notation, which represents the upper limit and its order is less than the degree of the highest order term present in the expression. Now, we have the expression 2n6 + 6n9 = O(n10), which is true because the degree of n10 in the expression O(n10) is greater than the highest order term present in the expression 2n6 + 6n9. So, it follows the rule of O-notation that is the upper limit and its order is greater than the degree of the highest order term present in the expression. So, 2n6 + 6n9 = O(n10). The third expression is 60n2 + 4n3 + 5n10 = O(n2), which is false because the highest degree of n is present in the expression is of n10. So, it cannot be reduced up to n2 using the O-notation. In other words, the degree of n2 in the expression O(n2) is lesser than the degree of the highest order term present in the expression 60n2 + 4n3 + 5n10. Hence, 60n2 + 4n3 + 5n10 ≠ O(n2).

After lowering the water table at depth of 20 ft., the degree of saturation decreased to 20%. Compute the effective vertical pressure at the mid-height of the clay layer in pounds per square foot 5002 psf
Given data:Degree of saturation (S) = 20%Elevation of groundwater table above datum = 0 ftDepth of water table after lowering = 20 ftEffective unit weight of silt (γ_s) = 122 pcfEffective unit weight of clay (γ_c) = 116 pcfThickness of clay layer (h_c) = 25 ftDistance of mid-height of the clay layer from the ground surface = y = 132 ftThe effective vertical pressure at the mid-height of the clay layer in pounds per square foot is 5002 psf.

A well penetrates an unconfined aquifer with a water level of 25 m prior to pumping. After a long period of pumping at constant rate of 0.05 m/s, the drawdowns at distances of 50 and 150 m from the well were observed to be 3 and 1.2 m, respectively. Compute the hydraulic conductivity of the aquifer and the radius of influence of the pumping well. [Ans: K = 18.3 m/day; r. = 327 m) 116
We know the following information:
Initial water level, Hi = 25 m
Final water level after pumping, Hf
Drawdowns at distances of 50m and 150m from the well are 3m and 1.2m, respectively.
The formula for hydraulic conductivity is as follows:
Q = KA (H1 - H2) / L
Where:Q = Rate of discharge
K = Hydraulic conductivity
A = Cross-sectional area of the aquifer
H1 = Initial water level
H2 = Steady-state water level
L = Length of the aquifer
In the steady-state flow, we have a constant discharge rate through the control boundary.
Steady-state flow means a state in which the flow rate at a specific point does not change over time.
Let's assume the distance of influence (i.e., the radius of influence) is r.
We can calculate the distance of influence using the following formula:
r = 0.35 * [(K * Q) / T]
Where:r = distance of influence
T = transmissivity
Q = discharge rate at the well's faceLet's find Q:
Q = VA
Where:V = velocity of the fluid
A = Cross-sectional area of the well
V = Q / A
Therefore, V = 0.05 / (pi * r^2).
Hence,
A = pi * r^2
Q = (0.05 / pi) * A
Therefore, Q = 0.05 * r^2 (Equation 1)
Drawdown at 50 m distance,
s1 = H1 - Hf
= 25 - 3
= 22 m
Drawdown at 150 m distance,
s2 = H1 - Hf
= 25 - 1.2
= 23.8 m
Substituting the values in the following equation, we get:
T = (K * B)
Where: B = Aquifer thicknessT = TransmissivitySince the aquifer is unconfined, B = h.
We have assumed
B = h
= 22 m.
Now, we can find K from the formula for transmissivity:
K = T / B
The formula for drawdown for a steady-state flow in an unconfined aquifer is:
s = Q / (2 * pi * T * h) * ln(r / rw)
Therefore,
s1 = Q / (2 * pi * T * h) * ln (50 / rw) ………. Equation (2)
s2 = Q / (2 * pi * T * h) * ln (150 / rw) ………. Equation (3)
From Equation (2) and (3), we have:
s1/s2 = ln (50 / rw) / ln (150 / rw)
Taking anti-log on both sides, we get:
50 / rw = (150 / rw)^s2/s1r
w = 150 / (50^(s2/s1))
Putting the values of s1, s2, and Q in the above equation, we get:
rw = 150 / (50^(23.8/22 - 3/22))r
w = 8.78 m
Now, the distance of influence can be determined from the formula:
r = 0.35 * [(K * Q) / T]
r = 0.35 * [(K * 0.05 * pi * 8.78^2) / (K * 22)]
Substituting the value of K and simplifying:
r = 327 m
Therefore, the hydraulic conductivity of the aquifer is K = 18.3 m/day, and the radius of influence of the pumping well is r = 327 m.

Which of the following is true of peering as it relates to internet traffic? O The use of file transfer protocol for larger files. O Internet service provider request to much user data. O A carrier can choose not to participate in peering. Some people use more bandwidth than others.
Peering is the process where two internet service providers (ISPs) agree to share their network traffic. The traffic is exchanged between the ISPs without charging the other one for it.
The following is true of peering as it relates to internet traffic:A carrier can choose not to participate in peering.Peering is an agreement between two ISPs.
Each provider agrees to carry the other provider's traffic to its destination. ISPs agree to peer with each other to expand their networks and improve their performance.
This agreement provides the benefit of lowering the costs of carrying traffic over the internet. This is because both ISPs will be carrying equal amounts of traffic, and so there will be no need for one to pay the other for carrying their traffic.A carrier can choose not to participate in peering because peering is not mandatory.
There are several reasons why a carrier might decide not to peer. For example, if a carrier is providing high-bandwidth services, such as streaming video, they may not want to peer with other carriers. This is because the carrier may have to pay for the bandwidth that they use, which can be expensive if they are using a lot of it.

For a buck converter, Vs = 20 V, V = 10 V, R = 50, L = 500 uH, C = 100 uF, the parasitic resistor of the inductor r=0.20 a) Write the state-space model for switch is on and off, respectively. b) Using state-space average method to deduce the state-space mode within a switching period. c) Derive the transfer function of iz(s)/vs(s), calculate its cut-off frequency.
A buck converter, also known as a step-down converter, is a type of DC-DC converter that reduces the input voltage to a lower output voltage. It is widely used in power electronics and is particularly efficient for applications where the output voltage needs to be lower than the input voltage.
a) State-Space Model for Buck Converter (Switch ON):
The state-space equations for the buck converter when the switch is ON can be written as follows:
Switch ON State:
[tex]dx(t)/dt = Ax(t) + Bu(t)[/tex]
[tex]y(t) = Cx(t) + Du(t)[/tex]
Where:
x(t) = [iL(t), vC(t)] is the state vector
u(t) = [Vs] is the input vector
y(t) = [iz(t)] is the output vector
The matrices A, B, C, and D can be determined based on the circuit equations and component values.
b) State-Space Model for Buck Converter (Switch OFF):
The state-space equations for the buck converter when the switch is OFF can be written as follows:
Switch OFF State:
[tex]dx(t)/dt = Ax(t) + Bu(t)[/tex]
[tex]y(t) = Cx(t) + Du(t)[/tex]
Where:
x(t) = [iL(t), vC(t)] is the state vector
u(t) = [0] is the input vector (since the switch is OFF)
y(t) = [iz(t)] is the output vector
The matrices A, B, C, and D can be determined based on the circuit equations and component values.
c) Transfer Function and Cut-off Frequency:
To derive the transfer function iz(s)/vs(s), we need to perform the Laplace transform on the state-space equations obtained in part (b).
The transfer function can be expressed as:
[tex]H(s) = C(sI - A)^(-1)B + D[/tex]
Once the transfer function is obtained, the cut-off frequency can be determined by analyzing the pole locations of the transfer function. The cut-off frequency is the frequency at which the magnitude of the transfer function decreases by -3 dB (half-power point).

If the time quantum of the round-robin scheduling policy is set to excessively large, then the round-robin policy naturally becomes a policy. O Multilevel Queue Scheduling Priority Driven page placement policy Earliest Deadline First O FCFS Shortest Job First
If the time quantum of the round-robin scheduling policy is set to excessively large, then the round-robin policy naturally becomes a policy with the following characteristics: OFCFS: In FCFS, the first process that comes in is the first process to be served. When the CPU completes the work assigned to one process, it proceeds to the next process in the queue.
FCFS is an appropriate option when it comes to process management if the processes have the same time quantum. Shortest Job First: SJF refers to selecting the process with the shortest burst time from the pool of available processes. As a result, the shortest job has a higher priority than the longer ones. SJF is the most effective scheduling algorithm in terms of average waiting time.
Earliest Deadline First: EDF policy is a real-time scheduling algorithm in which the process with the nearest deadline gets executed first. It's also referred to as Deadline Monotonic Scheduling.
EDF is designed for real-time scheduling and is frequently used in systems with hard real-time constraints, which need immediate processing to avoid catastrophic outcomes.

Customer (20%) The Customer class should store information about a customer's account. This includes ba- sic information such as their account ID (a 6 digit alphanumeric identifier), their name, their age (a whole number in years), their level of personal discount (none, CMP staff, or student), and their account balance (as an integer in pence, e.g. 1001 for £10.01). You should have two constructors, one for ID, name, age and discount type only that sets a default balance of zero, and another constructor that takes arguments for all fields including a specified balance (but the initial balance must be at least zero). The account balance is the amount of money that is in a customers account and it will be reduced appropriately each time a customer uses an arcade game (see the chargeAccount method below). A customer's balance should never be allowed to become negative - with the only exception that those with a student discount are also allowed to have a balance that goes as low as -500 (similar to an overdraft), and it would not be sensible to allow a negative starting balance for an account. Therefore, your construc- tors should throw an InvalidCustomerException if the account ID is incorrect or a negative balance is provided (you will need to provide this Exception class). Your class should include accessors for all fields and two methods for manipulating the bal- ance of an account - one to add to the balance and one to simulate accounts being charged. • First, the addFunds (int amount) method should allow a customer to top-up their ac- count balance (only add a positive amount to a balance and do not alter the balance if a negative amount is provided). • Second, there should be an instance method called chargeAccount that is used to sim- ulate a customer using an arcade game. This method should take two arguments, where one is an arcade game object and the other is a boolean to determine whether the ac- count is being charged during peak time. If a customer has a sufficient balance and is old enough to use an arcade game then the method should operate successfully and re- turn an int equal to the amount that the customer was charged (after any applicable discounts - remember, there are off-peak discounts for some games and CMP Staff re- ceive an additional 10% discount while students receive an additional 5% discount. Again, round down to the nearest integer if necessary when calculating prices). If the customer does not have sufficient funds to use the arcade game then their balance should be left unaltered and an InsufficientBalanceException should be thrown. Similarly, if the customer is not old enough to use the arcade game, their balance should be left unal- tered an a AgeLimitException should be thrown (you will need to create both of these sub-classes of Exception). Finally, ensure that your class also includes a suitable toString, helpful comments and evi- dence of testing. (Note: in practice, a customer's age would not be stored as an int and would likely be rep- resented by their date of birth. To keep it simple in this assignment though we are fixing it to be an int however and you can assume a customer's age will not change during the execution of your program). 748A66#Lucille Swan#800#31#STAFF 106498#Barry Guy#O#17 305459#Lewie King#3200#47 203685#Lois Romero#360#41#STAFF SGRQO1#Thea Worthington#800#17 889027 #Mikel Flinn#200#18#STUDENT 117DA4#Roshni Stephens#1000#15 6048D1#Macauly Rutledge#1400#37#STUDEN 512X13#Charles James-Warne#10#12 A64248#Amanda Pham#100#45 144374#Edwin Shea#100#24 546R82#Aman Crosby#380#62#STAFF 174450#Jonathan Wordle#200#19#STUDENT 2612CX#Kiri Kramer#3400#38 518370#Charis Jaramillo#3200#19#STUDEN 264474#Rowena Kaiser#1600#19#STUDENT 54A0N3#Moses Rivers#1000#20#STUDENT 506VX5#Catherine Chives-Keller#400#15 343172#Nour Buxton#1200#5 356965#Amy Mckinney#4000#17 522136#Khloe Stokes#1000#6 985F83#Jorge Pimento#200#23#STUDENT 901420#Paige Barclay#140#29 738164#Aoife Crouch#1000#29 9F0610#Aurora Mcleod#260#39#STAFF 387036#Irene Freeman#240#10 58R526#John-Paul clay#400#47#STAFF 973SA2#Jimmy Baker#1000#4 555765#Maaria Crossley#400#39#STAFF

discount = 10
elif self.discount == "Student":
discount = 5
price = game.get_price(peak_time) * (100 - discount) / 100
self.balance -= price
return price
def __repr__(self):
return "Customer(id=%s, name=%s, age=%d, discount=%s, balance=%d)" % (
self.id, self.name, self.age, self.discount, self.balance)
How does the above work?The above code implements the Customer class as described in the assignment.
The class has constructors for initializing a customer with a default balance and a specified balance. It also has methods for adding funds to the balance, charging the account for using an arcade game, and getting a string representation of the customer.
The class also raises exceptions if the ID is incorrect, the balance is negative, the customer does not have enough funds to pay for the game, or the customer is not old enough to play the game.

A circular footing with diameter 2.2m is 2.7m below the ground surface. Ground water table is located 1.5 m below the ground surface. Using terzaghi's equation, determine the gross allowable bearing capacity assuming local shear failure using the following parameters: - 27 degrees c=26 kPa Y = 20.3 KN/m³ ysat 22.3 KN/m³ FS = 3
According to Terzaghi’s formula, the gross allowable bearing capacity is given as:
Qa = cNc Sc + YNq Sq + 0.5 Y BNγIn the above formula, Qa is the gross allowable bearing capacity, c is the soil cohesion, Y is the unit weight of soil, Nc, Nq, and Nγ is the bearing capacity factors for cohesion, surcharge, and unit weight of soil, respectively. Sc and Sq are the bearing capacity factors for cohesion and surcharge, respectively. BNγ is the bearing capacity factor for unit weight, which is usually equal to 0.5 for strip and circular footings.γsat is the saturated unit weight of soil. FS is the factor of safety that is usually greater than 2.5.'
The given data is:
Diameter of the circular footing = 2.2 m
Depth of circular footing below the ground surface = 2.7 m
Location of the ground water table below the ground surface = 1.5 m
The unit weight of soil Y = 20.3 kN/m³
The saturated unit weight of soil γsat = 22.3 kN/m³The angle of internal friction of soil ϕ = 27°
The soil cohesion c = 26 kPa
The factor of safety FS = 3
The depth of circular footing below the ground surface is greater than its diameter; therefore, we can assume local shear failure, and use the following equation:
For circular footings, the bearing capacity factors Nc, Nq, and Nγ are given by:
Nc = (2Nq − 1) tan²(45° + 0.5ϕ)Nq = 1 + (sinϕ)γ BNγ = 0.5
The angle of internal friction of soil ϕ = 27°. Therefore, the value of Nq is:Nq = 1 + (sinϕ)γ BNq = 1 + (sin 27°) 22.3 × 0.5= 1.63
The value of Nc is:Nc = (2Nq − 1) tan²(45° + 0.5ϕ)= (2 × 1.63 − 1) tan²(45° + 0.5 × 27°)= 7.87
The bearing capacity factor for unit weight Nγ is 0.5.
For circular footings, the bearing capacity factors for cohesion Sc and surcharge Sq are given by:
Sc = 1 + 0.2 DNq Sq = 1 + 0.1 DNq
where D is the depth of the foundation.
The diameter of the circular footing is 2.2 m, and the depth of the footing is 2.7 m. Therefore,
D = 2.2Sc = 1 + 0.2 DNq= 1 + 0.2 × 2.2 × 1.63= 1.71Sq = 1 + 0.1 DNq= 1 + 0.1 × 2.2 × 1.63= 1.53
The gross allowable bearing capacity is given by:
Qa = cNc Sc + YNq Sq + 0.5 Y BNγ= 26 × 7.87 × 1.71 + 20.3 × 1.63 × 1.53 + 0.5 × 20.3 × 0.5× 2.2×(2.7−1.5)= 370.33 kN/m²
The gross allowable bearing capacity is 370.33 kN/m². Thus, the correct option is (D).
