3. The shaft shown in the figure is machined from AISI 1040 CD steel (Sut = 85 kpsi, Sy=
71 kpsi). The shaft rotates at 1600 rpm and is supported in rolling bearing at A and B.
The applied forces are F₁ = 2500 lbf and F₂ = 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.
