A 0.1 kg mass is suspended from a wire of negligible mass. The length of the wire is 1 m and its cross sectional area is `4.9 times 10^-7 m^2`. IF the mass is pulled a little in the vertically downward direction and released, it performs simple harmonic motion of angular frequency `140 rad.s^-1`. IF the young's modulus of the material of the wire is `n times 10^9 N.m^-2`. Find the value of n.

A copper wire of negligible mass of length 1 m and cross sectional area 10^-6 m^2 is kept on a smooth horizontal table with one end fixed. A ball of mass 1 kg is attached to the other end. The wire and the ball are revolving with an angular velocity of 20 rad.s^-1 . IF the elongation in the length of the wire is 10^-3m , obtain the Young's modulus. IF on increasing the angular velocity to 100 rad .s^-1 the wire breaks down, obtain the breaking stress.
