Also known as tension springs, extension springs are similar to compression springs but are loaded in tension. Hooks or loops are provided to allow a force to be applied, as extension springs are usually attached at both ends to other components. When these components move apart, the spring tries to bring them together again. Extension springs are wound to oppose extension and the tension of the wind can be manipulated to achieve the load requirements for a particular application. Tension springs are commonly used in machinery, levers, robotics, the automotive industry and they are a typical feature of a child’s back garden, due to their use in the mechanism of trampolines.
