Galvanized steel wire torsion spring

 

     A torsion spring is a type of spring that works by torsion or twisting; that is, a flexible elastic object that stores mechanical energy. The force of the spring is proportional to the amount of twist. The inverse relationship between the force required to produce a given amount of twist and the amount of twist produced by a given force is called springs rate or stiffness.

 

     A torsion spring is a type of spring that works by torsion or twisting; that is, it stores energy in the form of rotational potential energy. Springs of this type are usually made out of steel.
