A composite rod is made from stainless steel and iron and has a length of 0.469 m. The cross section of this composite rod is shown in the drawing below and consists of a square within a circle. Iron Stainless steel The square cross section of the steel is 1.05 cm on a side. The temperature at one end of the rod is 76.3 °C, while it is 16.9 °C at the other end. Assuming that no heat exits through the cylindrical outer surface, find the total amount of heat conducted through the rod in five minutes.
