A copper bus bar measuring 5cm by 10cm by 2.5m long is in a room in which the air is maintained at 300K. The bus bar is supported by two plastic pedestals to which it is attached by an adhesive. The pedestals are square in cross section, measuring 8 cm on a side. The pedestals are mounted on a wall whose temperature is 300K. If 1kW of energy is dissipated in the copper bar. What will be its equilibrium temperature? The convective heat transfer coefficient for all surfaces may be taken as 23W/m^2•K. The thermal conductivity of the plastic is 2.6W/m•K. Neglect thermal radiation.
