Extension springs are typically made from round wire that is tightly coiled to form a helical shape. They feature hooks, eyes, or loops at both ends to facilitate attachment to other components. When an external force pulls on the ends of the spring, it extends, storing energy within its coils. Once the force is removed, the spring contracts back to its original length, releasing the stored energy.
