Helical tension springs are similar to helical compression springs, but they try not to press but to pull. The hooks on the tip ensure that the pulling force can be applied.
& Nbsp; p> These springs, which resist dragging, are adjacent to windings except for exceptions. They are usually produced with right-handed winding and with a pre-tension. When the force applied to the pedestal exceeds this prestressing force, the bow begins to change shape.
