Hello students, here first let us consider free body diagram of point oa that is just this part.
00:15
Here the force acting at the point will be ox and here that is oy and the distance given for 0 .4 meter at point a ax and here that is ay.
00:36
The moment about the point o is equated to 0.
00:42
Hence ay into distance 0 .4 is equal to ax into 0 .4.
00:50
From this ax is equal to ay and it is equated to a.
00:58
Now again consider another free body diagram excluding previous one this.
01:06
Here summation of force along y axis is taken 0.
01:12
Here by plus ay is equal to 0.
01:18
Now by is equal to minus ay and we have taken that ay as a.
01:25
Therefore by is equal to minus a.
01:27
Again summation of force along x axis is equal to 0...
