Question

2. A steel bar 20.00 cm long is welded end to end with a brass bar 15.00 cm long. Both bars are insulated perfectly on their sides and each has a cross section area of 5.0o cm2. The free end of the steel bar is kept at 100°C and the free end of the brass bar is kept at 0°C. Consider Ksteel 50.2 w/m-Co, kbrass 0.800 w/m-Co. Find: A. the temperature at the junction of the bars B. the rate of heat flow in the composite bar.

    A long rod, insulated to prevent heat loss along its sides, is in perfect thermal contact with boiling water (at atmospheric pressure) at one end and with an ice-water mixture at the other. The rod consists of a 1.00 m section of copper (with one end in the boiling water) joined end-to-end to a length  L2 of steel (with one end in the ice water). Both sections of the rod have cross-sectional areas of 4.00 cm2. The temperature of the copper-steel junction...
