1 od compression spring

Torsion Springs received their name due to their twisted or contorted shape. The shape allows for a potential torque to be created due to its flexible elasticity. So with a calculated twist the power of these torsion springs can be harnessed.

There are a few different types of torsion springs. One is a torsion bar that is a straight but can be twisted about at its axis. It’s generally made of rubber or metal and can be twisted to create torque. For smaller more delicate uses there is a torsion fiber that is made up of silk, glass or even quartz. Another type of spring is the helical torsion spring. This takes the shape of a helix and is likewise twisted about at its axis to generate torque.

A common use of a torsion spring is in a mousetrap. The helix shaped spring is pulled twisted around a solid torsion bar. The spring is pulled back to create torque and fastened at a 180 degree angle. Once the trap is triggered the spring snaps back to original form catching whatever is in the baited area. Although a mouse trap is a fine example, this innovation has allowed for the creation of many of our commonly used devices in society to date.
