# Spring Energy

Written by Jerry Ratzlaff on . Posted in Fastener

Spring energy is the energy stored in elastic materials as the result of their stretching or compressing.

## formula

$$E_s = \frac {1}{2} k_s d_s ^2 \;$$

Where:

$$E_s$$ = spring energy

$$k_s$$ = spring constant

$$d_s$$ = spring displacement
