고체역학 (Gere) — Stresses in Beams (Basic Topics): Problem 5.8-4

5.8-4 A simply supported wood beam with overhang is subjected to uniformly distributed load \(q\). The beam has a rectangular cross section with width \(b = 200 \text{ mm}\) and height \(h = 250 \text{ mm}\). Determine the maximum permissible value \(q\) if the allowable bending stress is \(\sigma_{\text{all}} = 11 \text{ MPa}\), and the allowable shear stress is \(\tau_{\text{all}} = 1.2 \text{ MPa}\).
