This document discusses bending moment (BM), shear force (SF), and deflection in beams under different loading conditions. It provides examples of calculating the maximum BM for simply supported and cantilever beams with uniform and point loads. For a simply supported beam with a uniform load, the maximum BM is Wl/8. The maximum BM of a cantilever beam with a uniform load is Wl/2. The document also demonstrates how to draw the BM and SF diagrams for beams with overhanging sections, uniform loads partially covering the span, and multiple point loads. Conventionally, positive BM indicates concave upward deflection and negative BM indicates convex upward deflection.
