Use this calculator to determine the maximum deflection of a simply supported beam subjected to a point load at its center. Essential for structural analysis, engineering design, and educational purposes. Input beam length, load, material elasticity, and moment of inertia for quick, accurate results.
Formula:
δmax = (P × L3) / (48 × E × I)
Where:
P = Point Load (e.g., N, lbf)
L = Span Length (e.g., m, ft)
E = Modulus of Elasticity (e.g., Pa, psi)
I = Moment of Inertia (e.g., m4, in4)
δmax = Maximum Deflection
