Question details

The shaft shown in the figure is machined from AISI 1035 CD steel. The shaft rotates at 1,600 rpm and is supported in rolling bearings at and B. The applied forces are F1 2,300 lbf and F2-1,200 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. 8 in 8 in F2 1 1/4 in 17/8 in 1 1/4 in 1 5/8 in 13/4 in ר 10 in 10 in 1/2 in 1/2 in All fillets 1/16 in R.
