366811 A steel rail of length \(5\;m\) and area of cross section \(40\;c{m^2}\) is prevented from expanding along its length while the temperature rises by \(10^\circ C\). If coefficient of linear expansion and young's modulus of steel are \(1.2 \times {10^{ - 5}}\;{K^{ - 1}}\) and \(2 \times {10^{11}}N{m^{ - 2}}\) respectively, the force developed in the rail is approxmately:

Two rods of different metals having the same area of cross-section \(A\) are placed between the two massive walls as shown in figure. The first rod has a length \(l_{1}\), coefficient of linear expansion \(\alpha_{1}\) and Young's modulus \(Y_{1}\). The corresponding quantities for second rod are \(l_{2}, \alpha_{2}\) and \(Y_{2}\). The temperature of both the rods is now raised by \(\Delta T\). The displacement of the junction is
