The length of a wire is increased by 1 mm due to applied load. The wire of the same material have lengths and radius half that of the first wire, by the application of the same force, then extension produced will be

The length of a wire is increased by 1 mm on the application, of a given load. In a wire of the same material, but of length and radius twice that of the first, on application of the same load, extension is

Two parallel wires A and B of same meterial are fixed to rigid support at the upper ends and subjected to same load at the lower ends. The subjeted to same load at the lower ends. The lengths of the wire are in the ration 4 : 5 and their radii are in the ratio 4 : 3 the increase in the length of wire A is 1 mm. Calculate the increase in the length of wire A is 1mm. Calculate the increase in the length of the wire B.
