A torsion spring is a type of spring that works by twisting. It stores energy when it is twisted and releases that energy when it returns to its original position. These springs are commonly used in various applications, such as in clothes pins, garage doors, and toys, where rotational movement is needed. The design of a torsion spring typically consists of a coil of wire that is wound around a central axis. The amount of torque it can provide depends on its material, size, and the degree of twist. Torsion springs are essential components in many mechanical systems, providing reliable and efficient motion.
