고체역학 (Gere) — Axially Loaded Members: Problem 2.4-24

2.4-24 Find expressions for all support reaction forces in the plane frame with load 3P applied at C as shown in the figure. Joints A and D are pin supported, and there is a roller support at joint F. The lengths and the properties of the members are shown in the figure. Neglect the weights of all members. Select \( R_F \) as the redundant.
