`"Beam Maximum Deflection" = ( "F" * "L" ^3)/( "E" * "I" *48)`
Enter a value for all fields
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.
