Young's Modulus (or modulus of elasticity) measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material's linear elastic region.
💡
Pro Tips
Ensure consistent units. If using Pascals (Pa), use Newtons for force and square meters for area.
Young's Modulus is a property of the material, not its shape.
Strain is unitless (change in length / original length).

Fun Facts
"Diamond has one of the highest Young's Moduli (approx. 1220 GPa), making it incredibly stiff."
"Rubber has a very low Young's Modulus (approx. 0.01 - 0.1 GPa), which is why it stretches so easily."
"The concept is named after Thomas Young, a 19th-century British scientist."
