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.

Mechanical
Spring Force Calculator
Calculate the total force exerted by a spring given its spring constant, displacement, preload force, and safety factor. Useful for mechanical design, suspension systems, and actuator sizing.
