A composite rod consists of aluminum and steel rods of identical area of cross section placed in thermal contact end-to-end. The free end of the steel and aluminum rods kept at 100C and 0C respectively. Calculate the ratio of lengths: Length of steel/ Length of aluminum so that the temperature of the junction is at 50C.
i have been trying this problem for forever and i can't seem to get it! help me please!
thank you so much! ure a genius!
