c) Using Goodman's rule for shear stress, sm Ssa+ S Se Su se = 1, allow S determine the maximum allowable midrange shear stress as where Ssm is the midrange shear strength component, Ssa is the shear strength amplitude, and n is the safety factor. Use n = 1.2. n Hint: Observe that Ssa/Ssm = Fa/Fm, where Fa= Fmax-Fmin and Fm = (Fmax + Fmin)/2 are the amplitude and midrange of the cyclic loading. c) Using Goodman's rule for shear stress, sm Ssa+ S Se Su se = 1, allow S determine the maximum allowable midrange shear stress as where Ssm is the midrange shear strength component, Ssa is the shear strength amplitude, and n is the safety factor.
