A thin copper plate is compressed between two identical thick polymer plates. Heat is to be conducted 2 pts through one edge of the plate as shown.

a.) Determine the effective thermal conductivity in the direction shown. Assume that no heat is transferred from the top or bottom of the composite plate nor out the sides of length L and that the ends are at a constant temperature.

b.) What fraction of heat will be conducted through the copper plate?
