# Stiffness

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Stiffness, abbreviated as k, is the resistance of the elastic deformation of an object that applies to both compression and tension.

## Stiffness Formula

 $$\large{ k = \frac{F}{\delta} }$$

### Where:

$$\large{ k }$$ = stiffness

$$\large{ F }$$ = applied force

$$\large{ \delta }$$  (Greek symbol delta) = displacement
