So let us start with the solution.
00:03
So for the given question, we will do let u1, u2 come up to that as u of a, the value of a u at the interior match point, right? as per the given question.
00:28
So therefore, the boundary values of symmetrical about ab and hence u1 would become equals to u7, u2 would be equals to u8, u3 is equals to u9 are the values of u symmetrical about cd.
00:51
Now about a symmetrical to cd, u1 will be equals to u3, u4 is equals to u6 and u7 is equals to u9 and hence we just require the values of u1, u2, u4 and u5 to find it out, right? u4 and u5.
01:16
So let us find the initial value that is u5.
01:20
This will be equals to 1 by 4.
01:22
So from the given, it should be 2000 plus 2000 plus 1000 plus 1000 will comes out 1500.
01:35
I'm just taking the average and that is why i'm calculating the u of 5 and this is what the standard formula.
01:42
Now let us calculate u1.
01:44
So this can be goes to the 1 by 4, 0 plus 1500 plus 2000 plus 1000.
01:52
This i'm writing from the given diagram will comes out 1125.
01:58
This is 111500...
