Compute the fatigue life of the rotating hub and shaft assembly subjected to bending moment, axial thrust, bidirectional torque, and a uniform shrink fit pressure if at a critical point in the shaft, the state of stress is described by Ox,max = 1000 MPa, Ox, min = -800 MPa, Txy, max = 300 MPa, Txy,min = -100 MPa, and oy = 0z = Txz = Tyz = 0. Employ the maximum shear stress theory of failure together with the four criteria (Goodman, Soderberg, Gerber, SAE). Take Oyp = 1600 MPa, Ou = 2400 MPa, and K = 1. [Answer: Goodman Ncr = 2.89E6 cycles, Soderberg Ncr = 1.56E6 cycles, Gerber Ncr = 8.30E6 cycles, SAE Nor= 0.59E6 cycles] Compute the fatigue life of the rotating hub and shaft assembly subjected to bending moment, axial thrust, bidirectional torque, and a uniform shrink fit pressure if at a critical point in the shaft, the state of stress is described by Ox,max = 1000 MPa, Ox, min = -800 MPa, Txy, max = 300 MPa, Txy,min = -100 MPa, and oy = 0z = Txz = Tyz = 0.
