Hooke's law
Hooke's law (English: Hooke's law), is a basic law in the theory of mechanical elasticity, refers to the solid material force, stress and strain (unit deformation) into a linear relationship, to meet the material of this law is called linear elasticity or Hooke type material. That is, the force imparted by the spring to the object is linearly related to the amount of change in length X.
F=K*▲X
The law was proposed by the 17th century British physicist Robert Hooke. Steel can be regarded as a linear elastic material in most engineering applications, and Hooke's law applies in its elastic range (I. e. when the stress is lower than the yield strength).
