Maximum deflection for a beam supported at its ends can be expressed as:

    `delta = (F*L^3) / (E I 48)`

    where

  • δ = maximum deflection (m, mm, in)
  • E = modulus of elasticity (Pa (N/`m^2`), N/`mm^2`, psi)
  • F = load (N, lb)
  • L = length of beam (m, mm, in)
  • I = moment of Inertia (`m^4`,`"mm"^4`, `"in"^4`)

This equation computes the maximum deflection at the center when the load is concentrated at the center of the beam.
