WebHooke’s Law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. Mathematically, Hooke’s law is commonly expressed as: F = –k.x. Where F is the force, x is the extension in length, and k is the constant of proportionality known as the spring constant in N/m.
