Effective Energy Storage and Release in Spring Design
Designers create springs to store and release energy. When designers compress a spring, it stores the energy in the form of potential energy. The spring can release this potential energy when it returns to its original shape. In technical spring design, springs release energy in three main ways: compression, extension, and torsion.
