고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.3-19

4.3-19 Find expressions for shear force \( V \) and moment \( M \) at \( x = x_0 \) of beam \( AB \) in terms of peak load intensity \( q_0 \) and beam length variable \( L \). Let \( x_0 = 2L/3 \). The beam is a cantilever fixed at \( A \) with a distributed load defined by \( q(x) = q_0 \left( \frac{x}{L} \right)^2 \).
