Spring Calculator

A tool for estimating specifications for round-wire helical springs. By inputting parameters such as material, wire diameter, mean diameter, number of active coils, and working displacement, users can view the spring rate, load, stress, and stored energy. For extension springs, initial tension can be entered; for torsion springs, end-point force can be calculated based on the moment arm. A formula reference is readily available, and frequently used results are saved locally on the device.
