고체역학 (Gere) — Stresses in Beams (Basic Topics): Problem 5.5-14

5.5-14 A small dam of height \(h = 2.0 \text{ m}\) is constructed of vertical wood beams AB of thickness \(t = 120 \text{ mm}\), as shown in the figure. Consider the beams to be simply supported at the top and bottom. Determine the maximum bending stress \(\sigma_{\text{max}}\) in the beams, assuming that the weight density of water is \(\gamma = 9.81 \text{ kN/m}^3\).
