고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.5-28

4.5-28 A beam with simple supports is subjected to a trapezoidally distributed load (see figure). The intensity of the load varies from 1.0 kN/m at support A to 2.5 kN/m at support B. (a) Draw the shear-force and bending-moment diagrams for this beam. Assume that \( M_0 \) at B is zero. (b) Find the required moment \( M_0 \) at B so that the maximum moment in the beam does not exceed 1.0 kN·m.
