Online calculator for simply supported beam carrying point and uniform load

Bending moment and shear force calculator for simply supported beam carrying two point load.


simply supported beam carrying point and uniform load used in calculation of bending moment, shear force and deflection

In this page three tabs are created to calculate reaction forces at support, bending moment and shear forces.These pages also draws bending moment and shear force diagram.

Abbreviations for simply supported beam carrying point load at center.

  • BMD = Bending moment diagram.
  • SFD = Shear force diagram.

Note: to calculate reaction forces at support, bending moment and shear forces we need to input correct values.First point load distance is less than UDL starting point. Secondly, the distance of point and udl should be within the span of beam.
