Mechanical
Spring Force Calculator
Calculate the restoring force a spring exerts when compressed or stretched using Hooke's Law. Use it for spring selection, mechanism design, physics problems, and any application involving elastic force.

Mechanical
Spring Rate Calculator
Compute the spring rate (stiffness) of a helical compression spring from its wire and coil geometry. Use this during spring selection or custom spring design to match a required force-deflection characteristic.
