# Fixed Both Ends Beam - Point Load at Any PointMore Beams

Beam Calculator Input Units:
 Length of Beam, L: Distance to Load, a: Load on Beam, P: Point of interest, x: Youngs Modulus, E: Moment of Inertia, I:
 Resultant Force, R1=V1: Resultant Force, R2=V2: Moment, M1: Moment, M2: Moment at x, Mx: Max Deflection, ∆max: Deflection at Load, ∆a: Deflection at x, ∆x:
 Remember: 1m = 1000mm ; 1N/mm = 1000N/m ; 1Nm = 1000Nmm 1ft = 12in ; 1lbf.ft = 12lbf.in ; 12lbf/ft = 1lbf/in

The above beam force calculator is based on the provided equations and does not account for all mathematical and beam theory limitations. The calculator has been provided with educational purposes in mind and should be used accordingly. Unit conversion

# Notation and Units

## Metric and Imperial Units

The above beam design formulas may be used with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout with examples of units which should be adopted listed below:
