[" A steel wire of "1m" long and "1mm^(2)" cross section area is hang from rigid end.When weigh "],[" hung from it then change in length will be (given "Y=2times10^(11)N/m^(2)" ) "]

A stell wire of 1m long 1mm^(2) cross section area is hang from rigid end. The length of 1kg is hung from it then change in length will be (given Y = 2 xx 10^(11) N//m^(2) )

A uniform steel rod of length 1m and area of cross section 20 cm^2 is hanging from a fixed support. Find the increase in the length of the rod.

An aluminium wire and a steel wire of the same length and cross section are joined end to end. The composite wire is hung from a rigid support and the load is suspended at the free end. If Y_(AL) = 7xx10^(10) N//m^(2) and Y_("steel") = 7xx10^(11) N//m^(2) , the ratio of elongation of aluminium and steel wires is

A unifrom steel rod of length 1m and area of cross-section 20 cm^(2) is hanging from a fixed support. Find the increases in the length of the rod.

A unifrom steel wire of length 6 m and area of cross section 2 mm^(2) is elastically strectched through 3 mm. Calculate the energy stored in the wire. [Y_("steel") = 2xx 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))
