Extension Spring

An extension spring is a wire spring that reacts to forces pulling the ends apart and physically extending in shape, trying to offer resistance and return to its close coiled shape.

Extension springs 

can be manufactured to accommodate different loads, applications, or specific conditions by varying the size of the coil, the size of the wire or even by the length of the spring,  both ends are attached to other components. When these components move apart, the spring tries to bring them together again. Extension springs absorb and store energy as well as create a resistance to a pulling force. Extension Springs are wound to oppose extension. They are often tightly wound in the no-load position and have hooks, eyes, or other interface geometry at the ends to attach to the components they connect. They are frequently used to provide return force to components that extend in the actuated position.

Applications: Applications for extension springs include automotive interiors and exteriors, garage door assemblies, vise-grip pliers, carburetors, trampolines, washing devices, farm machinery, toys as well as thousands of other uses. Extension springs come in a wide array of sizes, from small medical devices to off-road machinery brake springs.

This type of resistance is why extension springs are used for everything from hardware to close screen doors or balance scales or even garage doors.
