An Extension Spring operates by extending when subjected to a load. It belongs to the broader category of helical springs, characterized by its helical coil shape. It consists of a tightly wound coil of wire with hooks at each end. The coil is formed by winding the wire around a mandrel or cylindrical rod, creating a helical shape. It provides a restoring force that brings parts back to their original position once the load is removed.Attributes:• A spring rate of 3.5 N/mm signifies the amount of force exerted by the spring of extension• The extension spring has a total of 20 coils responsible for deflection• The extension spring features a right-hand direction of coils to indicate the orientation of its helical windingsApplications:An Extension Spring stores potential energy when stretched. When a load or force is applied to the spring, it extends and resists the applied force, exerting an opposing force in the opposite direction.
