A 1.5-in-diameter bar has been machined from an AISI 1050 cold-drawn bar. This part is to withstand a fluctuating tensile load varying from 0 to 16 kip. Because of the ends, and the fillet radius, a fatigue stress-concentration factor Kf is 1.85 for 106 or larger life. Find and m and the factor of safety guarding against fatigue and first-cycle yielding, using (a) the Gerber fatigue line nd () the ASME elliptie fetigue line. Solution S,=84 ksi, S=100 ksi
