Vääntöjousen

A vääntöjousi, also known as a torsion spring in English, is a type of mechanical spring designed to store and release rotational energy. Unlike tension or compression springs that operate along a linear axis, a vääntöjousi functions by resisting an applied torque. When a torque is applied, the spring winds or unwinds, and its internal stresses store this energy. Releasing the torque allows the spring to return to its original position, releasing the stored energy.

These springs are typically made from a coiled wire, often a stiff metal like steel. The ends of the spring are designed to transmit the torque to or from the object it is attached to. Common applications for vääntöjouset include clothespins, garage doors, mousetraps, and automotive suspension systems. In these examples, the spring's ability to exert a rotational force and return to its set position is crucial for their function. The strength and behavior of a vääntöjousi are determined by factors such as the wire's material, diameter, the number of coils, and the coil's diameter. Understanding these parameters is essential for selecting the appropriate vääntöjousi for a specific application.
