What is analogous to the convection coefficient in structural analysis? (1)-prescribed displacement (2)-prescribed stress (3)-damping coeffcient (4)-elastic support (5)-coefficient of thermal expansion

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.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

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