How does the Beam Deflection Calculator work?

Input beam type (cantilever, simply supported, etc.), load type, material properties, and geometry Then: The calculator applies beam deflection formulas: δ = PL³/(3EI) for cantilever Then: Results show maximum deflection and compliance with limits.

Can you give an example of how to use the Beam Deflection Calculator?

Example: Input Cantilever, P=10 kN, L=3 m, EI=200 kN·m² gives a result of δ ≈ 45 mm (At L/4 deflection check).

Is the Beam Deflection Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Beam Deflection Calculator?

Our Beam Deflection Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
