What Is Young''s Modulus? Definition and Equation

Young''s modulus (E or Y) is a measure of a solid''s stiffness or resistance to elastic deformation under load. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed.
