The situation is similar to that of Prob. 6–14 wherein the imposed completely reversed axial load Fa = 3.8LN (1, 0.20) kip is to be carried by the link with a thickness to be specified by you, the designer. Use the 1020 cold-drawn steel of Prob. 6–14 with Sut = 68LN (1, 0.28) and Syt = 57LN (1, 0.058) kpsi. The reliability goal must exceed 0.99. Using the correlation method, specify the thickness t.
