What is a Torsion spring?

A torsion spring is a type of spring that stores energy by applying rotational or twisting force. This spring generates a restoring force when twisted along its axis. Torsion springs are typically made by winding a metal wire into a spiral shape, and when torque is applied, the spring exerts a force that tries to return to its original position. Torsion springs are used in various applications such as bicycle pedals, door closing mechanisms, measuring instruments, and toys. Unlike compression or tension springs, torsion springs are specialized for applications involving twisting forces.

Application of Torsion spring

✅ Bicycle pedals
Used to assist the rotation of the pedals.
✅ Door closing mechanisms
Used to automatically close doors.
✅ Toy mechanisms
Used to trigger movement in toys.
