Use the general shaft layout given and determine the critical diameters of the shaft
based on infinite fatigue life with a design factor of 1.5. Check for yielding. Check
the slopes at the bearings for satisfaction of the recommended limits in Table 7-2.
Assume that the deflections for the pulleys are not likely to be critical. The
material selected is 1050 Q and T. Given: Sut = 163 kpsi and Sy = 117 kpsi.
Use the following shaft layout assuming a gear transmits torque through a key and
keyseat at location A to another gear at location B.

A) Determine the location of the critical section on the shaft.
B) If the shaft's loading is fully reversed and the torque between
points A and B is constant, what are the values of the mean and alternating
torques and the mean and alternating moments in lbf-in?
