Definition and EquationNov 13,2019 Determination of Young s Modulus by Specific Vibration of#0183;Young's modulus (E or Y) is a measure of a solid's stiffness or resistance to elastic deformation under load.It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended,returning to its original shape when the load is removed.
