A cold-drawn AISI 1020 CD steel link is subjected to axial loading (which fluctuates from 0 to F) by pins that go through holes (Figure P7.12). What is the maximum value of F with a factor of safety of n, according to the Goodman criterion? Given: R = 10 mm, r = 4 mm, t = 2.5 mm, n = 1.4. Assumption: A reliability of 99.99% is used.
