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.
