The cold-drawn AISI 1040 steel bar shown in the figure is subjected to a completely reversed axial load fluctuating between 6300 lbf and 2700 lbf, both in tension. The diameter of the hole is 0.24 in. (a) Estimate the fatigue factor of safety based on the modified Goodman criteria and Gerber criteria (b) estimate the factor of safety based on the yield strength. Does this bar have infinite life for both criteria asked in part (a)? 1 in 0.4 in 0.24 in
