Young's modulus is a physical quantity that describes the ability of solid materials to resist deformation. A metal wire with a length of L and a cross-sectional area of ​​S is stretched by ΔL under the action of force F. F/S is called stress, and its physical meaning is the force per unit cross-sectional area of ​​the metal wire; ΔL/L is called strain, and its physical meaning is the elongation corresponding to the unit length of the metal wire. The ratio of stress to strain is called elastic modulus: that is. ΔL is a small change.

Young's modulus: Y = S / St

Y = Young's modulus

S = Normal stress

St = normal strain
