Beam Point Load at Any Position Calculator
Reactions, moment under the load and deflection for a point load anywhere on a simple span.
Moment peaks under the load; max deflection sits slightly toward midspan. At a = L/2 every formula collapses to the familiar centre-load case.
Formula
Beam Point Load at Any Position Calculator is a free point load any position for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Beam Point Load at Any Position Calculator
Reactions, moment under the load and deflection for a point load anywhere on a simple span. The calculation implements R_A = Pb/L; M = Pab/L; δ_load = Pa²b²/3EIL (Roark's Formulas; any strength-of-materials text). Moment peaks under the load; max deflection sits slightly toward midspan. At a = L/2 every formula collapses to the familiar centre-load case.
