Beam Calculator_

Calculate deflection and stress for simply supported beams with uniformly distributed loads

Inputs

Max Deflection

0.00 mm

At center of beam

Max Bending Stress

0.0 MPa

At outer fiber

Beam Weight

0.00 kg

Density: 7850 kg/m³

Moment of Inertia

0 mm⁴

I = bh³/12

Formulas Used

• Deflection: δ = (5 × w × L⁴) / (384 × E × I)

• Bending Stress: σ = (M × c) / I, where M = wL²/8

• Moment of Inertia: I = b × h³ / 12

• Weight: mass = volume × density

Note: This calculator assumes a simply supported beam with uniformly distributed load. For critical applications, consult with a structural engineer.
