Torsion Springs
Torsion springs are wire coiled cylinders used to store rotational energy or apply torque. Torque is the ability of a mechanism to twist around an axis. Unlike compression or extension springs, torsion springs are subject to rotational force (twisting) rather than linear force (pulling or pushing).
Torsion springs are made from a variety of steel materials, including stainless steel, hard drawn steel, steel music wire, and spring steel. Spring steel is a special kind of steel with increased elasticity and return properties. The elasticity of a torsion spring enables it to return to its original position; however, this capability diminishes with use.
Torsion springs come in a wide variety of sizes and are used in an array of applications. Garage doors are an example of a mechanism that uses larger torsion springs. Smaller torsions springs are used in an assortment of products, including hinges, CD players, clothes pins, and digital cameras.
