In the above question the ratio of the elongation produced in the copper wire and steel wire are

One end of a steel wire of radius .r. is fixed to a ceiling and a load of 3 kg is attached to the free end of the wire. Another wire made of copper of radius .2r. is attached to the bottom of 3 kg load and a 2 kg load is attached to the free end of the copper wire. The ratio of longitudinal strains produced in copper and steel wires is (Young modulus of steel =20xx10^(10)Nm^(-2) ) (Young modulus of copper =12xx10^(10)Nm^(-2) )

Two wires have diameters in the ratio 1:2 , length in the ratio 3:4 and young's moduli in the ratio 2:3. What is the ratio of elongations produced in the wires if they are subjected to the same streching force ?

Two wires have diameters in the ratio 2:1 , lengths in the ratio 4:3 and Young's modulus in the ratio 5:3 . The ratio of elongations produced in the wires when subjected to the same stretching force is

One end of a horizontal thick copper wire of length 2 L and radius 2R is welded to an end of another horizontal thin copper wire of length L and radius R. When the arrangement is stretched by applying forces at two ends, find the ratio of the elongation in the thin wire to that in the thick wire.

One end of a horizontal thick copper wire of length 2L and radius 2R is welded to an end fo another horizontal thin copper wire of lenth L and radius R. When the arrangement is stretched by applying forces at two ends, the ratio of the elongation in the thin wire to that in the thick wire is
