고체역학 (Gere) — Stresses in Beams (Advanced Topics): Problem 6.4-16

6.4-16 Repeat Problem 6.4-14 but use the configuration of UPN 200 channel shapes and loading shown in the figure. Use \(P = 250 \text{ N}\). (Reference from Problem 6.4-14: A cantilever beam of length \(L = 4.5 \text{ m}\) supports an inclined load \(P\) at its free end. Data for the beam include \(L = 4.5 \text{ m}\) and an inclination angle \(\alpha = 30^\circ\). For Problem 6.4-16, the cross-section consists of two UPN 200 channels arranged back-to-back as shown in the accompanying figure.)
