About springs

Adjustable Long Flexible Steel Wire Pulling Coil Garage Door Tension Extension Spring is listed under Springs — compression, extension, torsion, die and constant-force springs. Springs are mechanical devices designed to store and release elastic energy, typically in response to a compressive, tensile, or torsional force. The primary types include compression springs, which resist compressive loads along their axis; extension springs, which resist tensile loads and often feature hooks or loops at their ends; torsion springs, which apply torque or store rotational energy;
