고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.3-14

4.3-14 Find shear ($V$) and moment ($M$) at $x = 3L/4$ for the beam shown in Fig. a. Let $M_A = 24 \text{ kN}\cdot\text{m}$, $P = 48 \text{ kN}$, $L = 6 \text{ m}$, and $q_0 = 8 \text{ kN/m}$. Repeat for the beam in Fig. b (first solve for the reaction moment at fixed support $A$).
