고체역학 (Gere) — Axially Loaded Members: Problem 2.3-27

2.3-27 A vertical steel bar \(ABC\) is pin-supported at its upper end and loaded by a force \(P_1\) at its lower end. A horizontal beam \(BDE\) is pinned to the vertical bar at joint \(B\) and supported at point \(D\). Load \(P_2\) and moment \(M\) are applied at end \(E\). Calculate the vertical displacement \(\delta_C\) at point \(C\) if the loads are \(P_1 = 11\text{ kN}\), \(P_2 = 4.5\text{ kN}\), and \(M = 2.8\text{ kN}\cdot\text{m}\). The modulus of elasticity is \(E = 200\text{ GPa}\) and cross-sectional areas are \(A_1 = 160\text{ mm}^2\) and \(A_2 = 100\text{ mm}^2\). Ignore the weight of the bar.
