What is the temperature of the aluminium...

What is the temperature of the aluminium junction in the steady state of the system shown in Fig. Length of the load `=15.0` cm, length of the aluminium rod `=10.0` cm temperature of the furnace = `400" "^(@)C`, temperature of the other end `=0" "^(@)C`. The area of cross section of the lead rod is twice that of the aluminium rod.
(Thermal conductivity of steel `=34.9" J s"^(-1)m^(-1)K^(-1),` and copper `=205" J s"^(-1)m-1" "K^(-1)`)
