Acircular shaft is subjected to a static bending moment m and a torque t. apply the distortion energy theorem to obtain the following expression for the required radius,
r=(4/π^2s^2_y[4m^2+3t^2])^1/6

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.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
