About Beam Deflection Calculator

The Beam Deflection Calculator allows mechanical engineers and students to calculate deflection of beams under load for different support conditions such as cantilever and simply supported beams.

Formulas Used

• Cantilever Beam (end load): δ = WL³ / (3EI)
• Simply Supported Beam (center load): δ = WL³ / (48EI)

Applications

• ✅ Structural design
• ✅ Mechanical component analysis
• ✅ Bridge engineering
• ✅ Beam strength verification

FAQs

1. What is beam deflection?

Beam deflection is the displacement of a structural element under loading.

2. Why is Young’s modulus important?

Young’s modulus defines the stiffness of the material, directly affecting deflection.

3. Can I use this tool for distributed loads?

No, this tool currently supports point loads only.

4. Why is deflection important?

Excessive deflection can lead to failure, misalignment, or unsafe structures.
