The 60-mm-diameter shft rotates at 400 rev/min. This motion is caused by the unequal belt tensions on the pulley of 850 N and 350 N. Determine the power transmitted and the maximum shear stress developed in the shaft.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

An air compression refrigeration system is to have an air pressure of 100 psia in the brine tank and an allowable air temperature increase of 60°f for standard vapor compression cycle temperatures of 77 f entering the expansion cylinder and 14 f entering the compression cylinder, calculate the coefficient of performance a. 2.5 b 3.3 c. 4.0 d. 5.0

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
