WebYoung's modulus Y for a material is defined as the ratio of tensile stress to tensile strain. The tensile stress is the force per unit area F/A, and the strain is the proportional increase in length parallel to the applied force δx/x. If we divide the area elements of A = y 2, we have one intermolecular bond and its force F to consider.
