(a) When strain is small, the ratio of the longitudinal stress to the corresponding longitudinal strain is called the Young’s modulus (Y) of the material of the body. Where F is force, A the area,
Given Since, Young’s modulus is a property of material, we have Hence, extension produced is same as that in the other wire. |
