Springs

A piece of metal who’s properties are in a smaller space due to its twists that allows it to have more defined elastic properties.

Spring Constant

Taken from Young’s Modulus $k=E\frac{A}{L}$

Parallel & Series Springs

Series Springs

Double length, same area covered. $k=E\frac{A}{L}$ $A=A$ $L=2L$ $\therefore$ $k_{effective}=\frac{1}{2}k$

Parallel Springs

Same length but double the area covered. $k=E\frac{A}{L}$ $A=2A$ $L=L$ $\therefore$ $k_{effective}=2k$
