Beam Deflection Calculator

Calculate the deflection of a simply supported beam under a central load.

Beam Deflection

Enter the parameters to calculate beam deflection.

Formula Used:

δ = (F × L³) / (48 × E × I)

Where:

  • δ = Maximum deflection
  • F = Applied load (N)
  • L = Beam length (m)
  • E = Elastic modulus (Pa)
  • I = Moment of inertia (m⁴)
