Question

.The shaft shown in the figure is machined from AISI 1040 CD steel. The shaft rotates at 1600rpm and is supported in rolling bearings at A and B. The applied

forces are F1 = 2500 Ibf andF2 = 1000 lbf. Determine the minimum fatigue factor of safety based on achieving infinite life.If infinite life is not predicted, estimate the number of cycles to failure. Also check for yielding.
