Tension Springs

Tension springs are tightly wound coils that are designed to operate with tension. The spring stretches to a specific length as the Load/force is applied to it. In an unloaded positon, the loops of the spring are touching, with either a loop or hook attached at one end, and it is when this attachment is directed with force that the spring stretches. When thes components are pulled apart, usually from either side, the spring tries to hold itself together, causing the springing action, until the force is stopped and it can return to its original form.
