Required information steady A bar of steel has the minimum properties Se=40 kpsi, Sy= 60 kpsi, and Sut- 80 kpsi. The bar is subjected to a torsional stress of 1 kpsi and an alternating bending stress of 22 kpsi. Find the factor of safety guarding against a static failure and either the factor of safety guarding against a fatigue failure or the expected fe of the part. For the fatigue analysis, use 1. Modified Goodman criterion 2. Gerber criterion 3. Morrow criterion Take Ta 0 kpsi and Om = 0 kpsi. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What are the values of the alternating and mean von Mises stresses? The alternating von Mises stress is 0 kpsi. The mean von Mises stress is kpsi.
