고체역학 (Gere) — Axially Loaded Members: Problem 2.5-10

2.5-10 Repeat Problem 2.5-9 for the flat bar shown in the figure but assume that \(\Delta T = 30^\circ\text{C}\), and that \(\alpha = 19 \times 10^{-6}/^\circ\text{C}\), \(L = 2\text{ m}\), \(t = 20\text{ mm}\), \(b_1 = 100\text{ mm}\), \(b_2 = 115\text{ mm}\), and \(E = 96\text{ GPa}\). (From Problem 2.5-9: A flat aluminum alloy bar is fixed at both ends. ... If the temperature of the bar is raised uniformly ... find reactions at \(A\) and \(C\). What is the displacement at \(B\)?)
