Three rods of material X and three rods ...

Three rods of material X and three rods of material Y are connected as shown in the figure. All the rods are of identical length and cross-sectional area. If the end A is maintained at `60^@C` and the junction E at `10^@C`. Calculate the temperature of the junction B, C and D. The thermal conductivity of X is `0.92cal//sec-cm^@C` and that of Y is `0.46cal//sec-cm-^@C`.
