Welcome to the Beam Deflection Calculator guide — a free online engineering tool, with no sign-up required.

What is Beam Deflection?

It is how much a beam bends under a load. This tool computes max deflection and slope.

How to Use

Open the Beam Deflection Calculator
Enter the central load in newtons
Enter beam length, elastic modulus, and moment of inertia
See deflection in mm and slope in radians

Why It Matters

Engineers check deflection to keep structures safe and within building code limits.

Useful Tips

Use consistent SI units
Steel E is about 200 GPa
Deflection limit is often L/360

FAQ

What is the formula?

For a central load on a simply supported beam: δ = PL³/48EI.
