고체역학 (Gere) — Axially Loaded Members: Problem 2.3-30

2.3-30 Repeat Problem 2.3-29 if vertical load \( P \) at \( D \) is replaced by a horizontal load \( P \) at \( D \) (see figure). From Problem 2.3-29: A T-frame structure is composed of prismatic beam \( ABC \) and nonprismatic column \( DBF \) that are joined at \( B \) by a frictionless pin connection. The beam has a sliding support at \( A \) and the column is pin supported at \( F \) (see figure). Beam \( ABC \) and column segment \( DB \) have cross-sectional area \( A \); column segment \( BF \) have area \( 2A \). The modulus of elasticity \( E \) is the same for both members. Load \( 2P \) is applied downward at \( C \)... Find expressions for the downward displacements of column \( DBF \) at \( D \) (\( \delta_D \)) and also at \( B \) (\( \delta_B \)). Plot axial force (AFD) and axial displacement (ADD) diagrams for column \( DBF \).
