Beam Deflection Calculator
Calculate beam deflection for different support conditions and loading types. Essential tool for structural engineering and design.
Understanding Beam Deflection
Beam deflection is the displacement of a beam from its original position when subjected to loads. This calculator helps engineers determine maximum deflection for different beam configurations.
Beam Support Types
Different support conditions significantly affect beam deflection behavior:
- Simply Supported: Beam is supported at both ends but free to rotate. Most common in bridges and floor beams.
- Cantilever: Beam is fixed at one end and free at the other. Common in balconies and overhangs.
- Fixed Both Ends: Beam is rigidly fixed at both ends, preventing rotation. Provides maximum stiffness.
Key Parameters
Beam deflection depends on four critical parameters:
- E: Elastic Modulus - Material stiffness property
- I: Moment of Inertia - Cross-sectional shape property
- L: Beam Length - Distance between supports
- P/w: Applied Load - Force causing deflection
Engineering Applications
Structural Engineering
Design buildings, bridges, and other structures to meet deflection limits and ensure occupant comfort and structural integrity.
Mechanical Design
Design machine components, shafts, and mechanical systems where deflection affects performance and precision.
