Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. The law is named after 17th-century British physicist ...

This law describes the restoring force of a spring when it is stretched, stating that there is a linear relationship between this force (F spring) and the displacement (x) of the spring. At equilibrium, the restoring force of the spring should also be equivalent in magnitude to the force applied on the spring by the hanging mass.

Springs can be made out of a variety of materials but are frequently made out of spring steel which is a low alloy, medium carbon steel or sometimes high carbon steel with high yield strength. Small springs are frequently wound from pre-hardened stock, while larger springs are usually made from annealed steel and then hardened after fabrication.

The modified transom is less than 13% heavier but more than a 13% stronger lowering maximum bending stress to an acceptable level. You will notice that whilst the impact force (' F ') has increased due to reduced deflection (' y '), there is sufficient increased structural strength in the second moment of area of the new transom to lessen the resultant bending stress.
