Question

Three rods of identical cross-sectional area are made from the same metal form the sides of an isosceles triangle abc, right angled at b. The points a and b are maintained at temperatures t and respectively. In the steady state, the temperature of the point c is tc. Assuming that only heat conduction takes place, is

Answer 1

The transfer of thermal energy from one single body to another and from one particular temperature to other - high to low temperature is possible only under steady or unsteady conditions. In this question, there is steady state which means temperature does not change with time, at point c the temperature would remain same which is Tc.  

Therefore, heat conduction takes place is equal to 3T/1+ √2.
