There are no stress concentrations. The load line is propositional. The material has a yield strength
of Sy = 130 ksi, an ultimate strength of Su = 200 ksi, and a fully corrected endurance limit of Sn :
75 ksi. Calculate the:
(a) Static factor of safety using the MSSTF,
(b) Static factor of safety using the DETF,
(c) Fatigue factor of safety using the Soderberg criterion,
(d) Fatigue factor of safety using the Goodman criterion,
(e) Fatigue factor of safety using the ASME elliptic criterion.
