To determine the Young's modulus of a wire, the formula is Y=(F)/(A)xx(L)/(DeltaL) , where L = length, A = area of cross-section of the wire, DeltaL = change in length of the wire when stretched with a force F. The conversion factor to change it from CGS to MKS system is

A wire of length L,area of cross section A is hanging from a fixed support. The length of the wire changes to L_1 when mass M is suspended from its free end. The expression for Young's modulus is:

A load w is suspended from a wire of length l and area of cross-section A. Change in length of the wire is say Deltal . Change in length Deltal can be increased to two times by increasing
