They are also essential for toys and tools, for example in retractable key rings and tightening hand tools through which tension occurs. Extension springs are mandatory in trampolines because they stretch and contract when trampoline users jump.
Torsion Springs: Functionality, Types and Industrial Uses
Torsion springs are spiral and have a curved nature, either clockwise or counterclockwise, for the purpose of storing and recovering mechanical energy. This type of springs, unlike compression and discuss data extension springs, are not subjected to a linear force of compression or extension, but rather to rotational or angular forces.
The terminals of the spring are usually in contact with other parts. By rotating the central part of the spring, the spring coils and can thus store energy. When the force is released, the potential energy causes the spring to return to its position and provides the torque necessary to rotate the other parts.

How Torsion Springs Store and Release Energy
Torsion springs operate under the effect of a force in the form of torque, which causes the spring to rotate. Torque is directly related to the angle of twist and the spring constant, as well as the wire diameter and the geometry of the coil. When a torsion spring is twisted, it stores energy in the form of elastic potential energy in the spring material. When the load is released, the energy is transformed into kinetic energy, which allows the spring to apply a force to the rest of the components that help return the body to its original position.
This mechanism is widely applicable to different applications, such as providing limited rotation, simultaneously ensuring specific orientation of components or creating tension in automatic systems.
Common Industrial Applications of Torsion Springs
Torsion springs are essential components in various industries and trades that require control of rotational force. In automotive applications, they are essential in trunk lids, hood hinges, and tailgates to control opening and closing movements. Additionally, torsion springs are useful in steering, where they help return the steering wheel to its center position, as we will see later.
In aerospace, they are essential in aircraft control volume parts, such as ailerons and flaps, to facilitate restoring force and true alignment. Torsion springs also help support the deployment and retraction of landing gear mechanisms so they can operate smoothly and without a hitch.
