Cantilever Beam Deflection

Maximum deflection of a cantilever with an end load.

Formula

δ=FL33EI\delta = \frac{F L^3}{3 E I}

Variables

FLoad
LLength
EModulus
IMoment of inertia

Example

Deflection grows with the cube of length

Did You Know?

Doubling the length increases deflection eightfold.
