A heat-conducting rod, 1.60 m long and wrapped in insulation, is made of an aluminum section that is 0.90 m long and a copper section that is 0.70 m long. Both sections have a cross-sectional area of 0.00040 m2. The aluminum end and the copper end are maintained at temperatures of 30 degrees Celcius and 170 degrees Celcius, respectively. The thermal conductivities of aluminum and copper are 205 W/m * K (aluminum) and 385 W/m * K (copper). At what rate is heat conducted in the rod under steady-state conditions?
