Question: Repeat Prob. 662 using the Goodman criterion. Repeat Prob. 662, The material properties of a machine part are Sut = 85 kpsi, f = 0.86,

Repeat Prob. 6–62 using the Goodman criterion.
Repeat Prob. 6–62, The material properties of a machine part are Sut = 85 kpsi, f = 0.86, and a fully corrected endurance limit of Se = 45 kpsi. The part is to be cycled at σa = 35 kpsi and σm = 30 kpsi for 12 (103) cycles. Using the Gerber criterion, estimate the new endurance limit after cycling.
(a) Use Miner’s method.
(b) Use Manson’s method.
