A student performs an experiment to determine the Young's modulus of a wire ,
by Searle's method. In a particular reading ,
exactly 2 m long ,
the student measures the extension in the length of the wire to be 0.8 mm with an uncertainity of 0.05 mm at a load of exactly 1.0 kg. The student also measures the diameter of the wire ,
In the determination of Young’s modulus (Y = 4MLg/pie l d^2) by using Searle’s method, a wire of length L = 2 m and diameter d = 0.5 mm is used. For a load M = 2.5 kg, an extension l = 0.25 mm in the length of the wire is observed.
