Coiled springs are mechanical devices made from flexible materials, typically metal, that store and release energy. They are designed in a spiral shape, allowing them to compress or extend when force is applied. This design enables them to absorb shock, maintain tension, or provide resistance in various applications. These springs are commonly used in everyday items, such as pens, mattresses, and automobiles. They play a crucial role in machinery, helping to control movement and provide stability. Coiled springs come in various sizes and strengths, making them versatile components in both industrial and consumer products.
