고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.5-8

4.5-8 A simply supported beam \( ABC \) is loaded by a vertical load \( P \) acting at the end of a bracket \( BDE \) (see figure). (a) Draw the shear-force and bending-moment diagrams for beam \( ABC \). (b) Now assume that load \( P \) at \( E \) is directed to the right. The vertical dimension \( BD \) is \( L/5 \). Draw axial-force, shear-force, and bending-moment diagrams for \( ABC \).
