An alumminium rod and steel wire of same length and cross-section are attached end to end. Then compound wire is hung fron a rigid support and load is suspended from the free end. Y for steel is `((20)/(7))` times of aluminium. The ratio of increase in length of steel wire to the aluminium wire is

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 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 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))

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)
