Which term describes the top or bottom component of a trussed beam

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false
