Beam Deflection & Moment Equations
delta_{max} = frac{P L^3}{3 E I} quad (text{Cantilever Point Load}); quad M_{max} = P L; quad delta_{allow} = frac{L}{250}
Engineering Specifications & Method of Calculation
Structural mechanics analysis tool for cantilever and simply supported beams with point loads and uniformly distributed loads (UDL).
Serviceability Deflection Limits
Under standard building codes (AISC / Eurocode / IS 800), total beam deflection under service loads must not exceed span length divided by 250 (L/250) to prevent plaster cracking and architectural damage.
