the pitch point im pritty sure what is is
The point of contact of two pitch circles of mating gears is called the pitch point.
What is the pitch point?
A pitch point is where two pitch circles frequently come into touch. A common point of contact between two pitch circles of mating gears is called a pitch point. The pitch circle and is centered on the top of the teeth. Dedendum circle, also known as the root circle, is the circle traced through the base of the tooth.
The pressure angle, often known as the “tooth shape,” is the angle at which pressure from one gear's tooth is transferred to another gear's tooth. Pure rolling motion will occur at pitch point.
Therefore, it is pressure point.

Describe how self-healing polymers could be useful in the construction of
plastic frames for glasses and sunglasses.
Answer:
This can be achieved through the use of a built-in fiber-optic network of cables that deliver light and heat energy to the point of breakage.
Explanation:
Self-healing polymers are materials designed to aid the internal healing of materials like plastics, and metals. Shape-memory materials used in the making of plastic frames for glasses and sunglasses allow these materials to snap back into shape when they crack.
This is possible because heat is needed to help a deformed material regain its shape. Built-in fiber-optic network of cables serve the purpose of delivering heat to the deformed or cracked area, thus helping them to regain their shape.

Assume that 50,000 yd3 of the soil from a local borrow pit in Rhode Island, with a water content of 13% and dry unit weight of 87 pcf, is to be delivered to a construction site for some repairs of highway in I-95. By the time it reaches the site, the water content is 9%. It will be compacted to a minimum of 90% of the modified Proctor maximum dry density. Determine the total amount of water (in pounds), that must be added to the soil to increase the moisture content to the optimum level. Assume a Gs
Answer:3000 yd3
Explanation:
so i got the 50000 divided it by 100 times that by 13 and got 4500 yd3
so now the soil is at 9 so i need to get the 4 percent back up so i yet again got 50000 yd3 and divided by 100 and times it by 9 to get 1500 yd3 to then minus my 1500 and 4500 yd3 and got 3000 yd3 i hope it is right.

Explanation:
The bottom of a pan is made of a 4-mm-thick aluminum layer. In order to increase the rate of heat transfer through the bottom of the pan, a design was proposed for the bottom that consists of a 3-mm-thick copper layer sandwiched between two 2-mm-thick aluminum layers. Assume a perfect contact between the layers. Will the new design conduct heat better
Answer:
Yes, the new product will not conduct heat better
Explanation:
The bottom of the former product is made up of a 4mm thick aluminum layer
The new design is made up of two 2mm thick aluminum layer with a 3mm thick copper layer sandwiched in between.
These two materials are great conductors of heat.
As for copper, if one end is heated , the other ends rapidly reaches the same temperature, Copper is known as the best conductor of heat, that is, allows quick heat transfer. This ability of copper makes it highly used in applications where quick heat transfer is important, like the saucepans where rapid heat transfer is required.
As for aluminum, it is also a great heat conductor and twice as good as copper.
But the heat conductivity of copper is greater than aluminum and this will allow a faster heat transfer between the layers.

Rigid bar ACB is supported by an elastic cir-cular strut DC having an outer diameter of 15 in. and inner diameter of 14.4 in. The strut is made of steel with a modulus elasticity of load P 5kips5 E 5 29,000 ksi. Point is applied at B. Calculate the change in length of the circular strut DC. What is the vertical displacement of the rigid bar at point B
Answer:
The change in length of the circular strut DC = 0.0028 in.
The vertical displacement of the rigid bar at point B = 0.00378 in.
Explanation:
We have the following parameters or information in the question given above:
=> The outer diameter = 15 in., the inner diameter = 14.4 in., the modulus elasticity of E = 29,000 ksi, and the Point load P = 5kips.
The diagram showing the rigid bar ACB is supported by an elastic cir-cular strut DC is given in the attached picture below.
According to Newton's law of motion, it can be seen that the force on CD, that is FCD is equal and opposite to ACD. Hence, FCD = ACD.
Where FCD = p × [4 + 5] ÷ [sin Ф × 4].
kindly note that from the diagram sin Ф = 3/5, cos Ф = 4/5 and tan Ф = 3/4. Also p =5.
Hence, FCD =[ 5 × 9] ÷ [3/5 × 4] = 18.75 kip. So FCD = ACD.
The next thing here is to determine the area and length of CD, say the area of CD is G, thus, G = π/4 × [ 15² - 14.4²] = 13.854 in².
The lenght of CD is = √[4² + 3²] = √[16 + 9] = 5ft. Thus, 5 × 12 = 60in.
Hence, the change in length of the circular strut DC = [18.75 × 60] ÷ 13.854 × 29000 = 0.0028 in.
The vertical deflection of CD = 0.0028 × 3/5 = 0.00168 in.
We have that; 4 /CV = 9BV. Hence, BV = 9/4× CV.
(CV = vertical deflection of CD).
The vertical displacement of the rigid bar at point B = 9/ 4 × 0.00168 in = 0.00378 in.
Rigid bar ABC is supported by three symmetrically-positioned vertical rods, which are initially unstrained. After load P is applied, the normal strain in rods (2) is 0.0010 mm/mm. Determine the normal strain in rod (1) if there is a gap of 1.0 mm in the connection between rod (1) and the rigid bar at B. Report the strain in mm/mm
Answer:
The answer is below
Explanation:
The lengths of the rods are not given.
Let us assume the length of rod 1 = 1500 mm and the length of rod 2 = 800 mm
Solution:
The normal strain is defined as the change in member length δ divided by the initial member length L. The normal strain (ε) is:
ε = δ / L
δ = εL
For rod 1:
[tex]\delta_2=\epsilon_2 L_2\\\\\delta_2=0.0010\ mm/mm*1500\ mm=1.5\ mm[/tex]
The axial elongation of rod 2 is 1.5 mm. Since rigid bar ABC is attached to rod 2, the rigid bar move down by same amount.
The rigid bar moves down 1.8 mm but rods 1 will not be stretched by this amount. Because there is a gap between rod (1) and the rigid bar at B, the first deflection of 1 mm would not cause an elongation in rod 1. Therefore, the elongation in rods (1) is:
[tex]\delta_1=1.5\ mm-1\ mm=0.5\ mm[/tex]
The normal strain in rod 1 is:
[tex]\epsilon_1=\frac{\delta_1}{L_1} =\frac{0.5\ mm}{800\ mm} \\\\\epsilon_1=0.000625\ mm/mm[/tex]

Consider one-dimensional heat conduction through a large plane wall with no heat generation that is perfectly insulated on one side and is subjected to convection and radiation on the other side. It is claimed that under steady conditions, the temperature in a plane wall must be uniform (the same everywhere). Is this claim reasonable
Answer:
YES, this claim reasonable
Explanation:
the temperature in a plane wall is uniform since no heat is penetrating into the large plane wall and therefore, there is no heat transfer from the wall under steady conditions,
This condition will be met only when there are no temperature differences within the wall and the the outer surface temperature of the wall is equal to the temperature of its surrounding.
Therefore, Yes, this claim is reasonable

Calculate the percentage of recyclables in high socioeconomic localities.
Answer:
The percentage of recycling in high socioeconomic localities is 11.02%.
Explanation:
Since in high socioeconomic localities, 10% of paper is recycled, 12% of plastic, 1.7% of fabrics, 1.2% of rubbers, 0.9% of metals, 3.5% of glass, 33% of food wastes, 35% soil and 1.9% miscellaneous, to determine the average recycling percentage the following calculation must be performed:
(10 + 12 + 1.7 + 1.2 + 0.9 + 3.5 + 33 + 35 + 1.9) / 9 = X
99.2 / 9 = X
11.02 = X
Therefore, the percentage of recycling in high socioeconomic localities is 11.02%.

what is an unit resistance
Answer: Ohm Ω
Explanation:
The resistance can be defined as the hindrance offered to the flow of current. Lower the current the higher is the resistance. The SI unit of resistance is ohm Ω. When one ampere current flows from an object or wire the application of one volt of potential difference on it the resistance so produce is one ohm. Resistance can be achieved by the application of the certain gadgets in the circuit which can prevent the flow of excess current from devices and can prevent shock circuit.
Draw a FBD of the beam with reactions at A & B. A is a pin, B is a roller. Try to guess intuitively which way the vertical components of A & B are pointing. Do not show the 6 kN forces in your FBD. Only show the couple moment, or pure moment
Answer:
kindly check the drawing of the FBD of the beam with reactions at A & B. A is a pin, B is a roller in the attached picture.
Explanation:
Without further ado, let's dive straight into the solution to the question above. From the diagram of the FBD of the beam with reactions at A & B it can be shown that the reaction moment is anticlockwise while the moment is clockwise.
The system is at equilibrium and the it does not matter where you place the couple (pure) moment.
The distance from A to C can either be equal or not. If AY = 2.15 kN and M = 25.8. Then, the distance between A and B = 25.8/2.15 = 12m.

A three-phase transformer connection has a delta-connected secondary, and one of the transformers has been center-tapped to form a neutral conductor. The phase-to-neutral value of the center-tapped secondary winding is 120V. If the high leg is connected to a single-phase load, how much voltage will be applied to that load
Answer:
207.84 V will be applied to that load.
Explanation:
Given that;
The phase-to-neutral value of the center-tapped secondary winding is 120V
the high leg is connected to a single-phase load
voltage that will be applied to that load = ?
Now, the the high leg voltage will be 1.732 times the single phase center tapped voltage .
so
Load Voltage = 1.732 × 120V
Load Voltage = 207.84 V
Therefore, 207.84 V will be applied to that load.
