Physical Law
Hooke's Law applies to an ideal spring:
- $\mathbf F = -k \mathbf x$
where:
- $\mathbf F$ is the force caused by a displacement $\mathbf x$
- $k$ is the spring force constant.
The negative sign indicates that the force pulls in the opposite direction to that of the displacement imposed.
- The strain is proportional to the stress.
Also see
- Dimension of Spring Force Constant: the dimension of $k$ is $\mathsf {M T}^{-2}$.
