Beam Bending Stress & Deflection
Calculate the maximum bending moment, stress and deflection of a simply supported beam with a central point load or a uniform load, free online.
À propos de cette calculatrice
Simply supported beam: central load P gives M = PL/4 and δ = PL³ ÷ 48EI; a uniform load w (N/m over the span) gives M = wL²/8 and δ = 5wL⁴ ÷ 384EI. Bending stress σ = M·c ÷ I. A rectangular section has I = bh³/12; a solid round section I = πd⁴/64.
