Gere & Goodno — Stresses in Beams (Advanced Topics): Problem 6.10-12

6.10-12 Solve the preceding problem for a box beam with dimensions \(h = 0.5 \text{ m}\), \(b = 0.18 \text{ m}\), and \(t = 22 \text{ mm}\). The yield stress of the steel is \(210 \text{ MPa}\). (Preceding problem 6.10-11: Determine the yield moment \(M_Y\), plastic moment \(M_p\), and shape factor \(f\).)
