  1. $$\left( {{\text{p}} - 2{\text{d}}} \right){\text{t}}{\sigma _{\text{c}}}$$
  2. $$\left( {{\text{p}} - {\text{d}}} \right){\text{t}}\tau $$
  3. $$\left( {{\text{p}} - {\text{d}}} \right){\text{t}}{\sigma _{\text{t}}}$$
  4. $$\left( {2{\text{p}} - {\text{d}}} \right){\text{t}}{\sigma _{\text{t}}}$$

A composite wall consists of two plates A and B placed in series normal to the flow of heat. The thermal conductivities are kA and kB and the specific heat capacities are CPA and CPB for plates A and B respectively. Plate B has twice the thickness of plate A. At steady state, the temperature difference across plate A is greater than that across plate B, when?
