Gere & Goodno — Tension, Compression, and Shear: Problem 1.3-21

1.3-21 Find support reactions at A and D and then calculate the axial force N, shear force V, and bending moment M at mid-span of AB. Let \( L = 4.25 \text{ m} \), \( q_0 = 175 \text{ N/m} \), \( P = 225 \text{ N} \), and \( M_0 = 400 \text{ N}\cdot\text{m} \).
