Three bars of equal lenghts and equal area of cross-section are connected in series. Their thermal conductivities are in the ratio of `2:4:3`. If the open ends of the first and the last bars are at temperature `200^(@)C` and `180^(@)C` respectivity in the steady state, calculate the temperature of both the junctions.

If at the steady state the open ends of the first and the last bars are at temperature 200^(@)C and 20^(@)C respectively, find the temperature of both the junctions. .

Three cylindrical rods A, B and C of equal lengths and equal diameters are joined in series as shown if Fig. Their thermal conductivities are 2K, K and 0.5K, respectively. In steady state, if the free ends of rods A and C are at 100^@C and 0^@C , respectively, calculate the temperature at the two junction points.

Two ends of a conducting rod of varying cross-section are maintained at 200^(@)C and 0^(@)C respectively. In steady state:

Three rods of equal length and equal area of cross section are connected end to end in series. The open end of the first rod (from left) is at a temperature of 300^@C and that of the last rod is at 20^@C in steady state. If the thermal conductivities of rods from left to right are in the ratio of 1: 3: 4, then find the temperatures of both the junctions.

Two bars of same length and same cross-sectional area but of different thermal conductivites K_(1) and K_(2) are joined end to end as shown in the figure. One end of the compound bar it is at temperature T_(1) and the opposite end at temperature T_(2) (where T_(1) gt T_(2) ). The temperature of the junction is
