What is the maximum bending moment for a simply supported beam of span L carrying a concentrated load W at midspan?

Explanation

For a simply supported beam with a central point load W, reactions at both ends are W/2. Bending moment under the load is M_max = (W/2) * (L/2) = W * L / 4. For UDL w over full span, M_max = w * L^2 / 8.
