It’s not "Hookie's Law of Elasticity". Did you mean "Hooke's Law of Elasticity"?
Hooke's Law of Elasticity states that the amount of deformation (stretching or compressing) of a material is directly proportional to the force applied to it, as long as the material remains within its elastic limit. This means that when a force is applied to an elastic material, such as a spring, it will deform in proportion to the amount of force applied. The law is named after Robert Hooke, an English physicist and mathematician who first stated it in the 17th century.
The mathematical expression of Hooke's Law is:
F = -kx
where F is the force applied to the material, x is the amount of deformation (stretching or compressing), and k is a constant known as the spring constant, which measures the stiffness of the material. The negative sign indicates that the force and the deformation are in opposite directions.
Hooke's Law is used in many fields, such as physics, engineering, and materials science, to describe the behavior of elastic materials under stress and to design structures that can withstand certain loads.
