고체역학 (Beer) — Stress and Strain—Axial Loading: Problem 2.28

2.28 The length of the \(\frac{3}{32}\)-in.-diameter steel wire \(CD\) has been adjusted so that with no load applied, a gap of \(\frac{1}{16}\) in. exists between the end \(B\) of the rigid beam \(ACB\) and a contact point \(E\). Knowing that \(E = 29 \times 10^6\) psi, determine where a 50-lb block should be placed on the beam to cause contact between \(B\) and \(E\).
