    Assume that ##T_C## is between ##T_A## and ##T_B## and that there are equal heat flow rates ##B \rightarrow C## and ##C \rightarrow A## (because we want to calculate steady-state temperatures, and without the equality of the rates the ##T_C## would be changing).

    H = heat flow. Heat H1 flows down B->C. The problem says to assume only conduction (eg through the rods) no radiated losses so where else can that heat flow go if not down C->A ? Therefore H1=H2.
