spring
The spring is the most important part of this mechanical dimension, it stores and releases the mechanical energy. These components mainly offer resistance, damping as well as dynamic force limiting and energy transfer function between contact bodies (or lines). Depending on the application, this multipurpose component comes in various types (i.e., compression springs, extension springs or even a torsion spring), shapes and materials (steel (or titanium) and plastic). Actuator are described as indispensable parts in fields varying from automobile suspension systems to watches and fasteners for basic machines.
