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 ife of the part. For the fatigue
analysis, use
1. Modified Goodman criterion
2. Gerber criterion
3. Morrow criterion
Take Ta 0 kpsi and am= 0 kpsl.
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
