Cylinder copper rod of length `1m` and a cylinder steel rod of length `1.5m` are joined together end to end. The cross sectional area of eac rod is `3.14cm`. The free ends of steel rod and copper rods are maintained at `0^(@)C` and `100^(@)C` respectively. The surfaces of rods are thermally insulated. Find the temperature of copper steel junction. (Given thermal conductivity of steel `=46J//m-s.^(@)C` and the thermal conductivity of copper `=386J//m-s.^(@)C`)
