An object of mass m is suspended at the end of a massless wire of length L and area of cross -section A. Young modulus of the material of the wire is Y. If the mass is pulled down slightly its frequency of oscillation along the vertical direction is :

A point of mass m is suspended at the end of a massless wire of length l and cross-section A. If Y is the Young's modulus for the wire, obtain the frequency of oscillation for the simple harmonic motion along the vertical line. [Hint: If x is the displacement of mass m from the equilibrium position then Y = (stress)/(strain)= (F/A)/(x/l) or F = (YAx)/(l) and this force acts opposite to x. Now proceed as in example 3.
