Young's

Young's modulus, also known as the elastic modulus, measures a material’s stiffness—the ability to resist deformation under stress. It quantifies how much a material stretches or compresses when a force is applied, relative to its original size. A higher Young's modulus means the material is stiff and resists deformation, while a lower value indicates it’s more flexible. It's fundamental in engineering and materials science to predict how structures or components will behave under load, ensuring safety and durability in designs like bridges, airplanes, and bridges.
