Three identical rods are joined at a point. The free ends of two are kept at $7 0^{\circ}$ C and the free end of the third at $1 0^{\circ}$ C. Find the temperature of the junction in $^{\circ}$ C.

Answer:

Solution:

No net heat enters the junction: $(T - 10) = (70 - T) + (70 - T)$ , so $3 T = 150$ and $T = 5 0^{\circ}$ C.
