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.

When a force is applied along the length of the wire

The length and cross-section of the wire of meter bridge are

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)

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))

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)

If the resistance of wire A is three times the resistance of wire B and the two wires have the same length, compare their cross sectional areas. The two wires are made of the same material.

A wire of length L extends by l on application of force F. Suppose the wire is cut into 3 equal parts and the same force is applied to one of them. Now the extension will be

In a stretched wire under tension and fixed at both ends, the area of cross section of the wire is halved and the tension is doubled. The frequency of the wire will be

Two wires A and B are stretched by the same load. If the area of cross-section of wire 'A' is double that of 'B,' then the stress on 'B' is
