The spring is designed to operate with a tension load, so the spring stretches as the load is applied to it. The common hook types are:a. English Hook b. German Hook c. Lateral Round Hook d. Universal Hook e.The others (Pointed Hook, U type Hook, Semicircle Hook)
It is designed to operate with a compression load, so the spring gets shorter as the load is applied to it.
Wire forms have infinite uses and a wide variety of shapes and sizes. These forms can be a load bearing link with minimal deflection.
In other cases they can be used as a holder applying a spring tension where a static load is required.
Uunlike the above types in which the load is an axial force, the load applied to a torsion spring is a torque or twisting force, and the end of the spring rotates through an angle as the load is applied.
