A steel rotating-beam specimen has allowables Ftu=150 ksi, Fty=135 ksi. Determine (a) the fatigue strength Sf at 500 cycles, and (b) whether the specimen will fail if subjected to 130 ksi for 500 cycles.
Answer: (a) Sf_500=122.3 ksi; (b) Yes.
Please explain it step by step and provide formula. Thank you so much for your helping
