The following shaft is made of steel (Sut = 520 MPa, Se = 260 MPa) and is subjected to 3 loads at C; an axial load P, a bending force F, and a torque T. The shaft is fixed at its left end A. A fillet of 2 mm radius exists at B. The loads fluctuate such that Fmin = 0 and Fmax = 100 N, Pmin = 0 N and Pmax= 1000 N, and Tmin = 0 and Tmax = 100 N.m. For the shaft, find the factor of safety for infinite life (using Case 3 safety factor calculation) at B. Assume all fatigue stress concentration factors are equal to 1.
