Two wires, one made of capper and other of steel are joined end to end. (as show in figure). The area of cross-section of copper wire is twice that of steel wire, They ae placed under compressive force of magnitude F. Find the ratio of their lenghts such that change in lenght of both wire are same `(Y_(S)= 2 xx 10 ^(11) N//m^(2) and Y_(C) = 1.1 xx 10 ^(11) N//m^(2))`

Two wires of equal cross-section but one made of steel and the other of copper are joined end to end. When the cobination is kept under tension, the elongations in the two wires are found to be equal elongations in the two wire are found to be equal. What is the ratio of the lengths of the two wires? (Given, Young's modulus of steel = 2 xx 10^(11) Nm^(-2) and young's modulus of copper = 1.1 xx 10^(11) Nm^(-2) )

A weight of 100N is suspended by two wires made by steel and copper as shown in figure length of steel wire is 1m and copper wire is sqrt(3)m . Find ratio of change in length of copper wire (Deltal_(c)) to change in length of steel wire (Deltal_(s)) . given Young's modulus Y_("Steel") =2xx10^(11) N//m^(2),Y_("Copper")=1xx10^(11) N//m^(2)

In the above question the ratio of the elongation produced in the copper wire and steel wire are

In figure the upper wire is made of steel and the lower of copper. The wires have equal cross section. Find the ratio of the longitudinal strains developed in the two wires.
