+Young's Modulus, or the elastic modulus, quantifies a material's stiffness under linear [Stress](/wiki/stress) and [Strain](/wiki/strain). It reveals how much a material resists deformation when stretched or compressed, a fundamental property for understanding [Elasticity](/wiki/elasticity) in engineering and design.
