In physics, elasticity is a physical property of materials which return to their original shape after the stress that caused their deformation is no longer applied. For very small deformations, most elastic materials, such as springs, exhibit linear elasticity. This means that they are characterized by a linear relationship between stress and strain (the relative amount of deformation). To describe elastic properties of linear objects like wires, rods, or columns which are stretched or compressed, a convenient parameter is the ratio of the stress to the strain, a parameter called the “Young’s modulus” or “Modulus of Elasticity” of the material. Young’s modulus can be used to predict the elongation or compression of an object as long as the stress is less than the yield strength of the material. Among rubber, steel, wet clay and plastic; steel has the maximum elasticity ranging between 180-200 gpa.
