Two same length rods of brass and steel of equal cross-sectional area are joined end to end as shown in figure and supported between two rigid vertical walls. Initially the rods are unstrained. If the temperature of system is raised by Deltat . Find the displacement of the junction of two rods. Given that the coefficient of linear expansion and young's modulus of brass and steel are apha_(b).alpha_(s)(alpha_(b)gtalpha_(s)),Y_(b) and Y_(s) respectively.

Two rods of similar area of cross section and length are joined as shown in the figure. The ratio of their thermal conductivity is 2:3. The free ends are maintained at 100^(@)C and 0^(@)C respectivley. THE temperature at junction in steady state is
