A copper wire and steel wire both have the same length and radius are joined end to end, when the composite wire is hung from a rigid support, and the load attached at the free end, the increase in the length is found to be 1cm. Find the increase in length of copper steel wire. (Y for copper = `1.2 xx 10^11 N//m^2`, Y for steel =`2.1 xx 10^11 N//m^2)`

An aluminium wire and a steel wire are of the same length and crosssection and are joined end to end. The composite wire is hung from a rigid support, a load is suspended from the free end. If the increase in the length of composite wire is 2.77 mm, find the increase in length of each wire. ( Y_A = 7 xx 10^10 N/m^2) (Y steel= 2 xx 10^11 N//m^2)

A copper wire and a steel wire of same length and same cross-section are joined end to end. The compositive wire is hung from a rigid support and a load is suspended form the free end. The increase in length of the compositive wire is 4 mm. The increase in copper wire will be (Y_(copper)=1.2xx10^(11)N//m^(2),Y_(steel)=2xx10^(11)N//m^(2))

A composite wire is prepared by joining a tungsten wire and steel wire Both the wires are of the same length and same area of cross section. If this composite wire is suspended to a rigid support and a force is applied to its free end, it gets extended by 3.25 mm. Calculate the increase in length of tungsten wire and steel wire separately.

Two wires A and B are of the same material. Their lengths are in the ratio 1 : 2 and the diameter are in the ratio 2 : 1. If they are pulled by the same force, then increase in length will be in the ratio

A Copper wire and steel of the same diameter and length are connected end to end and a force is applied, which stretches their combined length by 1 cm. The two wires will have

Find the energy stored per unit volume of a steel wire of length 1m when it is stretched by 0.2mm. Given Y for steel = 2.1 x 10^11 N/m^2

If one end of a wire is fixed with a rigid support and the other end is streched by a force of 10N , then the increae in length is 0.5mm . The ratio of the energy of the wire and the work done in displacing it through 0.5mm by the weight is

The length of a copper wire increases by 0.01 metre, when it is loaded with 10 kg weight. Another copper wire of the same length but double the radius is loaded with the same weight. The increase in length of the second wire, in metre, will be

The ratio of the lengths of two wires A and B of same material is 1 :2 and the ratio of their diameters is 2:1. They are stretched by the same force, then the ratio of increase in length will be
