Question

Can someone please provide neat, correct work. Experts only please.

I 2 in 11 in in Problem Statement The shaft shown is rotating under loads F1 : 1 8.F2= 1.9 klbf. Dimensions are c 8, e 8.g 8.h-10, 10 n = 3 in. All fillets have l 16 radius. The critical location is at x= 10.5 point Q where the moment is high, the diameter small, and the fillet causes a stress concentration. The material is cold drawn steel with SUT-65, Sy= 65 kpsi. Assume Nt-103, Ne-100 Calculate the endurance limit Se adjusted for modifying factors. Calculate the reduction factor f from equations, not from chart. Calculate the intercept a of the high-cycle fatigue line. Calculate the slope b of the high-cycle fatigue line Calculate the fatigue stress concentration Kf adjusted for notch sensitivity q calculated from equations, not from chart. Calculate the number of cycles N to failure. Answer tolerance-4%, Use figures in the Appendix to estimate the theoretical stress concentration factor Kt You may use Tables A 9 to calculate the bending moment M Be sure to include units and the correct sign with your answers. Please use only in, lbf, and psi. Your answers: Se (psi)20707.26 psi f (no units) = a (no units)- b (no units)11817 Kf (no units)- N (no units)

Thank you
