An aluminum wire and a steel wire of the same length and cross-section are joined end to end. The compoiste wire is hung from a rigid support and a load is suspended from the free end. If the length of the composite wire is `2.7mm` then the increases in the length of wire is (in `mm`)
`(Y_(Al) = 2xx10^(11)Nm^(2), Y_("Steel") = 7xx10^(11) Nm^(-2))`

An aluminium wire and a steel wire of the same length and cross-section are joined end to end. The composite wire is hund from a rigid support and a load is suspended from the free end. If the increase in the length of the composite wire is 2.7mm, find the increase in the length of each wire. (Y_(Al)=0.7xx10^(11)Nm^(-2), Y_("steel")=2xx10^(11)Nm^(-2))

An aluminium wire and a steel wire both of the same length and cross-section are joined end to end . The composite wire is hung from a rigid support and a load is suspended from the free end . If the increase in length of the composite wire is 2.7 mm, find the increase in length of each wire. Y_al = 7 xx 10^10 N/m^2 and Y_steel = 2 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)

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 a load is suspen-ded from the free end. If the increase in lengthe of the composite wire is 1.35 mm, find the ratio the (i) stress in the two wires amd (ii) strain in the two wires. (Y_(Al)=0.7xx10^(!1)Nm^(-2),Y_("steel")=2=10^(11)Nm^(-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))
