Springs - TorsionTorsion springs are a type of spring that experiences torsional or twisting deflection when a load is applied. These springs are typically made of round wire and have different left- and right-hand coils, which give them the ability to exert a torque or rotary force. Torsion springs are commonly used in a variety of applications, including hinges, latches, and pulleys, where they store mechanical energy and help to provide resistance to rotational motion. Torsion springs are available in a range of sizes and materials, and can be designed to meet specific load and deflection requirements.
