Beam Deflection Calculator

Quickly calculate beam deflection, bending stress, and structural response for standard load cases.
Ideal for mechanical engineers, civil engineers, maintenance teams, and students working with beams, shafts, and structural elements. Just enter load, beam type, length, Young’s modulus, and moment of inertia — the tool instantly computes deflection & bending.

Bending Stress & Load Analysis Tool

The tool uses standard formulas: 1️⃣ Point Load at Center : δ=FL^3/48EI

2️⃣ Uniformly Distributed Load : δ=5wL^4/384EI

Where: F = Load (N), L = Beam length (m), E = Young’s Modulus (Pa), I = Area moment of inertia (m⁴)

🧭 How to Use

FAQ

1. What units should I use?

Use N, m, GPa, and m⁴ for correct output.

2. Does this support cantilever beams?

Not in this version — can be added if needed.

3. Is this calculator accurate for real structures?

Yes for theoretical estimation. Actual results vary based on material quality & constraints.

4. How can I calculate Moment of Inertia (I)?

You can compute using section formulas (rectangle, I-beam, pipe, etc.).
