Supported beam, point load in middle


Use this calculator to determine deflection of a profile with second moment of inertia I, length l and Young's Modulus E under influence of load F.

Optionally x can be used to determine the deflection at a specific point along the axis of the profile.

θmax νx νmax F l 2 l 2

\( v_{max}=\dfrac {\ Fl^{3}} {48EI} \)

\(θ=\dfrac {\ Fl^{2}} {16EI} \)

\(v_{x}=\dfrac {\ Fx} {48EIl} 3l^{2}-x^{2} \)
