An unevenly heated metal plate has temperature T(x, y) in degrees Celsius at a point (x, y). If T(2,1) = 115, T_x \, (2,1) = 17, and T_y \, (2,1) = -12, estimate the temperature at the point (2.02,0.95).

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.

On a average work day more than work place firs are reorted

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented
