Question
Rods of copper, brass, and steel—each with cross-sectional
area of 2.00 cm2—are welded together to form a Y-shaped figure. The
free end of the copper rod is maintained at 100.0°C, and the free ends of
the brass and steel rods at 0.0°C. Assume that there is no heat loss from
the surfaces of the rods. The lengths of the rods are: copper, 13.0 cm;
brass, 18.0 cm; steel, 24.0 cm. What is (a) the temperature of the junction
point; (b) the heat current in each of the three rods?
