"Specifying how stress and strain are to be measured, including directions, allows for many types of elastic moduli to be defined. The four primary ones are: 1. Young's modulus (E) describes tensile and compressive elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. It is often referred to simply as the elastic modulus. " - Elastic moment of resistance
