Question
Twelve conditioning rods from the sides of a uniform cube of side l. If in steady state, B and H ends of the cube are 100oC and 0oC respectively. Find the temperature of the junction ′A′ : -


Options
A.80oC
B.60oC
C.40oC
D.70oC
Solution
For the cube, net resistance = 
(Where R = Thermal resistance of each side)
H =
For side A
⇒ θA = 60oC
(Where R = Thermal resistance of each side)
H =
For side A
