Extension springs are mechanical devices that store energy and offer resistance when subjected to external forces. Extension springs work by resisting a load which stretches the spring and makes the spring longer. They are attached at both ends to other components and as the components move apart, the spring pulls them back together. Learn more about extension springs.
