# Cantilever beam

This online calculator is designed to calculate the stiffness of the cantilever beam from the Young’s Modulus.

Young modulus or the modulus of elasticity in tension is a mechanical property that measures the tensile stiffness of a solid material.

## Calculator

## Formula

Stiffness = (3 × E × I ) / l^{3}

- E – Young’s Modulus
- I – Area Moment of Inertia
- l – Length
