WebAnswer (1 of 2): Hook's law enunciates that the strain happening in a metal due to an induced stress by a force, is proporotional to the stress induced. This means in graph it is presented as a straight line. But this proportionality is only upto a point called yield point. As long as the induced... Consider a simple helical spring that has one end attached to some fixed object, while the free end is being pulled by a force whose magnitude is Fs. Suppose that the spring has reached a state of equilibrium, where its length is not changing anymore. Let x be the amount by which the free end of the spring was displaced from its "relaxed" position (when it is not being stretched). Hooke's law states that how to host django project on cloudflare
