Spring force magnitude
Estimate the force magnitude from a linear spring stiffness and extension or compression.
Method and scope
F = kx for the magnitude of the ideal linear spring force.
Use spring force magnitude for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Spring stiffness — N/m
- Extension or compression — m, cm, mm, in
SOURCE AND LIMITS
Assumptions: The spring is linear over the entered displacement. Extension is measured from the unloaded equilibrium length.
Limitations: The direction of the restoring force is not represented; the displayed result is a magnitude.
