WebThe equation for change in length is traditionally rearranged and written in the following form: F A = Y Δ L L 0. 5.34. The ratio of force to area, F A, is defined as stress (measured in N/m 2 ), and the ratio of the change in length to length, Δ L L 0, is defined as strain (a unitless quantity). 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.
