Question
The shaft shown in the figure is machined from AISI 1040 CD steel. The shaft rotates at 1600
rpm and is supported in rolling bearings at A and B. The applied forces are F1 = 2500 lbf and
F2 = 2500 lbf. The location of critical bending moment from 10.5" from point A, where
bending moment is 14 750 lbf·in.
Determine the minimum fatigue factor of safety based on achieving infinite life. Yield
strength is 71 kpsi. If infinite life is not predicted, estimate the number of cycles to failure.
Also check for yielding.
Note: for the given ratio of r/d = 0.0625/1.625 = 0.04, D/d = 1.875/1.625 = 1.15 the stress
concentration is given by K, =1.95. Also, use the correction of the endurance limit based on
the surface factor, ka, size factor, kb, and loading factor, ke
