Torsion springs are mechanical devices that store and release energy when twisted. They are designed to exert a torque or rotational force, making them useful in various applications, such as clothes pins, garage doors, and toys. The spring's design allows it to return to its original shape after being twisted, providing consistent performance. These springs are typically made from high-carbon steel or stainless steel, which gives them strength and durability. The amount of torque a torsion spring can provide depends on its size, material, and the number of coils. Proper installation and maintenance are essential for optimal function and longevity.
