Atransparent film is to be bonded onto the top surface of a solid plate inside a heated chamber. for the bond to cure properly, a temperature of 70°c is to be maintained at the bond, between the film and the solid plate. the transparent film has a thickness of 0.00105 m and thermal conductivity of 0.05 w/m¡k, while the solid plate is 0.014 m thick and has a thermal conductivity of 1.2 w/m¡k. inside the heated chamber, the convection heat transfer coefficient is 70 w/m^2k. if the bottom surface of the plate is maintained at 52c, determine the temperature inside the heated chamber and the surface temperature of the transparent film. assume thermal contact resistance is negligible.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
