Simply Supported Beam with Point Load Calculator to find forces, moments, stresses, deflections and slopes of a simply supported beam for a concentrated loading at any point. Simply supported beam with point load formulas are given below the calculator.
Simply Supported Beam with Point Load Calculator:
Note : Use dot "." as decimal separator.
Note * : P is positive in downward direction as shown in the figure and negative
in upward direction.
Note ** : For second moment of area calculations of structural beams, visit "

Note * : R_{1} and R_{2} are vertical end reactions at the left and right, respectively, and are positive upward. Shear forces and deflections are positive in upward direction and negative
in downward direction. All moments are positive when producing compression on the upper portion of the beam cross
section. All slopes are positive when up and to the right.
Note: Stresses are positive numbers, and these are stress magnitudes in the
beam. It does not distinguish between tension or compression of the structural
beam. This distinction depends on which side of the beam's neutral plane c input
corresponds.
