The situation is similar to that of Prob. 6–10 wherein the imposed completely reversed axial load Fa = 15 LN (1, 0.20) kN is to be carried by the link with a thickness to be specified by you, the designer. Use the 1018 cold-drawn steel of Prob. 6–10 with Sut = 440 LN (1, 0.30) MPa and Syt =370 LN (1, 0.061). The reliability goal must exceed 0.999. Using the correlation method, specify the thickness t.
