A solid rod of length 21 and coefficient of thermal conductivity k, is joined end to end with another rod, of length I and coefficient of thermal conductivity 4k. The rods have the same cross-sectional area. The steady temperature of the free end of the rod of length 21 is T₁ and the steady temperature of the free end of the rod of length / is T2 with T₁ > T2 Assume that no heat escapes from the sides of the rods. The temperature, T, of the interface between the two rods will be: (ST1+T₂) 9 (7 + 87₂) 9 (T₁+2T₂) 3 O (T1+T₂) 2 (27+7₂) 3
