The breaking stress of the metal is ( 40 / 3 pie ) x 10^6 N/mm^2 . What should be the minmum radius of the wire used if it is not to break? Take g = 10 m/s^2

A wire is stretched 1 mm by a force of 1 kN. How far would a wire of the same material and length but of four times that diameter be stretched by the same force?
