young's modulus is a physical quantity that describes the ability of a solid material to resist deformation. a wire of length l and cross-sectional area s stretches δl under the action of force f. f/s is called stress, and its physical meaning is the force exerted by the 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 amount of change.

young's modulus: y＝s/st

y = young's modulus

s = normal stress

st = normal strain
