# Hooke's Law

Written by Jerry Ratzlaff on . Posted in Fastener

Hooke's law states that the amount of spring force, compressed or stretched, is proportional applied to the spring deformation.

## formula

$$F_s = -k_s d_s$$

Where:

$$F_s$$ = spring force (applied force)

$$k_s$$ = spring constant

$$d_s$$ = spring displacement
