Question

Two bars of equal length and the same cross - sectional area but of different thermal conductivities, K1 and K2, are joined end to end as shown in Fig. One end of the composite bar is maintained at temperature Th whereas the opposite end is held at Tc. If there are no heat losses from the sides of the bars, the temperature Tj of the junction in steady state is given by
