A wire of length area of cross-section is hanging from a fixed support. The length of the wire changes to when mass is suspended from its free end. The expression for Young’s modulus is:
To solve this problem, we need to find the expression for Young's modulus of the wire.Young's modulus is defined as the ratio of tensile stress to tensile strain.Tensile stress is given by:
