Young’s modulus, also referred to as the Young modulus, is a mechanical property of substances that offers insight into the stiffness of that material in its solid form. Young’s modulus provides a relationship between the strain on an object (the proportional deformation of an object) and the stress applied on it (which can be thought of as the force applied to the object per unit area of object). The Young modulus is named after the British polymath and physician Thomas Young. It is important to note that a solid material undergoes some elastic deformation whenever a small load of weight is applied to it. It can also be noted that the elastic deformation of solid materials is reversible.
