Question
three rods of identical cross-sectional area and made from the same material from the sides of an isoscales traangles ABC, right angled at B. The point A and B are maintained at temperatures T and (√2)T respectively. In the steady state, the temperature of the point C is Tc. Assuming that only head conduction take place, Tc / T is
Options
A.
B.
C.
D.
Solution
The diagramatic representation of the given problem is shown in figure. Since, TA / TB the heat will flow B to A. Similarly, heat will also flow from B to C and C to A. Applying the conduction formula
To the sides CA and BC, we get
⇒
3T = TC(√2 + 1)
⇒
∴ Correct option is (b).
