+Young's Modulus, often called the elastic modulus, quantifies a material's [Stiffness](/wiki/stiffness) – its resistance to elastic deformation under stress. This fundamental [Material Property](/wiki/material_property) is crucial in engineering, revealing the linear relationship between stress and strain before permanent change occurs.
