고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.5-24

4.5-24 The beam $ABCD$ shown in the figure has overhangs that extend in both directions for a distance of 4.2 m from the supports at $B$ and $C$, which are 1.2 m apart. Draw the shear-force and bending-moment diagrams for this overhanging beam.
