Beam deflection is a equilibrium between bending moment, material properties, and geometry.The formula is given by:
Where:
- δ is the deflection at the center of the beam
- P is the applied load
- L is the length of the beam
- E is the modulus of elasticity of the beam material
- I is the second moment of area (also known as the moment of inertia) of the beam’s cross-sectional shape.
