Beam Load Calculator

Calculate support reactions and bending moments on a beam with concentrated loads and distributed loads. Engineering calculator for statics, structural analysis, and civil engineering students. Includes shear force and bending moment diagrams for simply supported and cantilever beams.

Support Reactions for Concentrated Load

RA = (P × b) / L, RB = (P × a) / L

Keterangan:

  • P
    Concentrated load (N)
  • a
    Distance from support A (m)
  • b
    Distance from support B (m)
  • L
    Total beam length (m)
  • RA
    Support reaction at A (N)
  • RB
    Support reaction at B (N)

How to Use the Beam Load Calculator

  1. 1

    Enter Load

    Enter the concentrated load P in newtons (N).

  2. 2

    Enter Dimensions

    Enter distances a, b, and total length L in meters.

  3. 3

    Calculate

    Get support reactions RA and RB.

Contoh Perhitungan

Simply Supported Beam

Soal:

P = 1000 N, a = 2 m, b = 3 m, L = 5 m. Find RA and RB?

Penyelesaian:
  1. 1.RA = (1000 × 3) / 5 = 600 N
  2. 2.RB = (1000 × 2) / 5 = 400 N
Hasil:RA = 600 N, RB = 400 N

Support reaction at A is 600 N and at B is 400 N.

Pertanyaan yang Sering Diajukan (FAQ)

What is a simply supported beam?
A beam with two simple supports—typically pinned at one end and roller at the other.
When is this formula valid?
Valid for a statically determinate beam with a single concentrated load.
