Hello friends, we are here to solve a problem and the problem says three rods of material x and three rods of material y are corrected as shown in the diagram.
00:09
All the three rods of identical length and cross -sectional area if the end a is maintained at 60 degrees celsius and the direction e is maintained at 10 degrees celsius.
00:19
Calculate the temperature of junction c, the thermal conductivity of x is given and that of y is also good.
00:26
Now let us see how this problem can be solved.
00:28
First of all, we have to treat the given network of rod in terms of thermal resistance rx and ry.
00:35
I hope you don't have any problem.
00:37
Now, i can write that rx will have the value l over a multiplied .92.
00:44
And here we will have the value ry, which is equals to l over a multiplied .46.
00:51
Now, i can say that here you need to know that how i can write this very thing.
00:57
I have written this very thing as r equals l over ak and we are going to solve this problem using what we are going to use in this problem, we are going to treat the given network of rod in terms of thermal resistance.
01:11
So i hope there is no such problem till now.
01:14
Now i can say that if, okay, so if rx equals r and ry equals 2 rx, okay, so it will become 2rx and it will become 2r.
01:29
Then what you can infer from these data that note as in bridge p over q as in bridge, the bridge is balanced, that is temperature at junction c and d is equal and the rod cd becomes inactive, ineffective as no heat will flow through it...
