Answer: True
Explanation:Typical metals have a property of ductility and malleability that is metals can be drawn into wires or any other shape by beating or stretching the metal by putting the tensile strength or shear strength that pulls them apart . But while compression the metals are squeezed together which affects the hardness of a metal and they are not able to bear the compression force well and thus cannot show elastic-plastic behavior while compression .Therefore the statement given is true typical metals show elastic-plastic behavior in tension and shear but not in compression.

Explanation:
Given
Diametrical Pitch
where T= no of teeths
D=diameter
module(m) of gears must be same
Let be the gears on two gears
Therefore Center distance is given by
thus
and Velocity ratio is given by
From 1 & 2 we get
The answer would be for a .7 and b is 1.3 and c is .8
Answer:
The increase in pressure of the gas is found to be 15.92 KPa
Explanation:
The additional pressure is equivalent to the pressure exerted by the weight of the mass increased over the area of piston:
Increase in Pressure = ΔP = Weight/Area
ΔP = mg/πr²
m = mass = 25 kg
g = 9.8 m/s²
r = radius of cylinder = 7 cm = 0.07 m
ΔP = (25 kg)(9.8 m/s²)/π(0.07 m)²
ΔP = 245 N/0.01539 m²
<u>ΔP = 15.92 KPa</u>
Therefore, the increase in pressure of gas is 15.92 KPa.
