About Deflection of Beam Calculator

The Deflection of Beam Calculator is a free tool for mechanical and civil engineering students to calculate maximum deflection in a simply supported beam under a central point load. It uses the standard formula:

δ = (W × L³) / (48 × E × I)

Where:

• W = Applied Load (N)
• L = Length of Beam (mm)
• E = Young’s Modulus (N/mm²)
• I = Moment of Inertia (mm⁴)
• δ = Maximum Deflection (mm)

Why Use This Tool?

• ✅ Quick deflection calculation
• ✅ Useful in strength of materials and design of beams
• ✅ Helps students verify numerical problems
• ✅ Free online beam deflection calculator

FAQs on Beam Deflection

1. What is beam deflection?

Beam deflection is the displacement of a structural element under applied load. It shows how much a beam bends.

2. Which formula is used here?

This calculator uses δ = (W × L³) / (48 × E × I), valid for a simply supported beam with central point load.

3. Can this be used for other loading conditions?

No ❌, this tool is specifically for central point load. For other load cases, different formulas are used.

4. Why is deflection important?

Deflection is critical in structural safety. Excessive deflection can cause cracks, misalignment, or failure in beams.
