4) Compute the fatigue life of a rotating hub and shaft assembly, if at a critical point in the shaft, the state of stress is described by σxx,max = 1000 MPa, σxx,min=-800 MPa, Txy,max = 300 MPa, Txy,min = -100 MPa, and σyy = σzz = Txz = σyz = 0. Employ the maximum shear stress thory of failure together with modified Goodman criterion. Take σ₁ = 2400 MPa and the fatigue-strength reduction factor K=1. [Use fracture stress as 0.9 times the ultimate stress, endurance stress as (1/3) times K times the ultimate stress, N = 103 cycles and Ne=108 cycles]
