Beam Load with UDL and Point Load Calculator
Result
Beam Load with UDL and Point Load Calculator (Simple) Estimate the bending moment, shear force and deflection of a simply supported beam under a uniformly distributed load, a central point load, or both. Enter the span and loads to get the peak bending moment at midspan, the max — free online calcul
Formula
- Beam Load with UDL and Point Load Calculator calculates its result from Wl, Pl, Principal. It uses the formula M_udl = wL²/8; M_point = PL/4; Shear = wL/2 + P/2; Deflection assumes EI = 20,000 kN·m². Change any input to recalculate the result instantly.
- The main inputs are Wl, Pl, Principal. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Beam Load with UDL and Point Load
- Wl: 2
- Pl: 3
- Principal: 4
Using Wl = 2, Pl = 3, Principal = 4, the calculated result is 3.
