Let us take the vertical reactions at a and b as r a and r b.
00:05
So, these are the vertical reactions at a comma.
00:15
Now, by resolving the moment and force, we can write r a plus r b is equal to, let us consider this as our equation number 1.
00:25
And summation of the moments at point a will be equal to 0.
00:30
0 or we can write as p into p into k by 2 is equal to rb into k or we can write rb is equal to p by so from equation we can write r is equal to rb equal to p so we can write r is also equal to p by from equation number 1.
01:00
So, we know that theta b equal to 0 which because we are taking this as the reference.
01:08
So, by using the moment area method we can write theta p minus theta b is equal to 1 by p i into area of p p dash b of b m that is half into l by l into p l by which we can write as theta p minus theta b is equal to p l square divided by 16 into ei.
01:40
So, we have theta b equal to 0.
01:42
So, therefore, we can write theta p is equal to p l square divided by 16 into ei...
