In physics, Hooke's law is an empirical law which 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, Fs = 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 Robert … WebStiffness is the resistance of an elastic body to deflection or deformation by an applied force - and can be expressed as. k = F / δ (1) where . k = stiffness (N/m, lb/in) F = applied force …
