고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.5-13

4.5-13 The simple beam AB supports a triangular load of maximum intensity \( q_0 = 1.75 \text{ kN/m} \) acting over one-half of the span and a concentrated load \( P = 350 \text{ N} \) acting at midspan (see figure). Draw the shear-force and bending-moment diagrams for this beam.
