# Stiffness

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

## Formulas that use Stiffness

\(\large{ k = \frac{F}{\delta} }\) |

### Where:

\(\large{ k }\) = stiffness

\(\large{ F }\) = applied force

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