A1.5-in-diameter bar has been machined from an aisi 1050 cold-drawn bar. this part is withstand a fluctuating tensile stress varying from 0 to 18.0 kpsi. because of the ends, and the fill radius, a fatigue stress-concentration factor ky is 1.6 for 10 or larger life. the fully correcte endurance limit is s 34 kpsi, sat= 100 kpsi and s, 84 kpsi. find the factor of safety guardin against fatigue, using the modified goodman fatigue line and first-cycle yielding
