Question: Problem 2 (25 Points) The shaft shown in figure is machined from AISI 1040 CD steel. The shaft rotates at 1600 rpm and is supported

Problem 2 (25 Points) The shaft shown in 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 = 1000 1bf and F2 = 2500 1bf. Determine the minimum fatigue factor of safety based on achieving infinite life. Use q = 0.75. Draw the bending moment diagram to get full credit. F1 F2 1'4 in 8 in 8 in 8 in 1/s in 17/'s in 134 in 1'4 in 1/2 in - 10 in 10 in 3 in 12 in A B All fillets 1/16 in R
