Required information A bar of steel has the minimum properties Se= 40 kpsi, Sy= 60 kpsi, and Sut= 80 kpsi. The bar is subjected to a steady torsional stress of 8 kpsi and an alternating bending stress of 5 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 life 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 is the factor of safety against yielding? The factor of safety against yielding is
