Beam Deflection Calculator

Simply Supported Center Load

This calculator estimates maximum deflection of a simply supported beam with a point load at the center.

Method: It applies the elastic beam formula delta = P x L^3 / (48 x E x I). Use consistent SI units.

Understanding Beam Deflection

1. What This Calculator Measures

Beam deflection estimates how much a simply supported beam bends under a center point load.

2. How the Calculation Works

The calculator applies the standard elastic deflection equation using load, span, modulus, and moment of inertia.

3. Formula or Rule Used

delta = P x L^3 / (48 x E x I).
