Abar of steel has the minimum properties se =40 kpsi. 5y = 60 kpsi, and sat, = 80 kpsi. the bar is subjected to a steadytorsional stress of 15 kpsi and an alternating bending stress of 25 kpsi. find the factor of safety guarding against a staticfailure, and either the factor of safety guarding against a fatigue failure or the expected life of the part. for the fatigueanalysis use: (a) modified goodman criterion.(bl gerber criterion.(6) asme-elliptic criterion.
