# 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.

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

$$θ=\dfrac {\ Fl^{2}} {16EI}$$

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