If the load put onto a spring increases the rate of the spring, the spring is said to have a progressive rate. Progressive rate It is not uncommon for even well designed and properly manufactured springs to settle up to 1% of their free height. It needs to be pointed out, however, that in cases where a poorly designed spring is subject toAug 29, 2012  Hooks break for many reasons but the main cause is stress created from bending the wire to make the hook. Flipping up a hook causes the wire in that area to weaken. If high stresses are then applied to the extension spring, the hook may snap even though the rest of the spring can handle the load.Most extension springs are wound with initial tension. This is an internal force that holds the coils tightly together. The measure of the initial tension is the load necessary to overcome the internal force and just start coil separation. Unlike a compression spring, which has zero load at zero deflection, an extension spring
