Employ the maximum shearstress thory of failure together with modified Goodman criterion. Take σ₁ = 2400 MPa and thefatigue-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]
