Data from the given portion.
00:11
So, there is the truss in the diagram is supported by a pin at a and a roller at b.
00:41
So, there is the truss.
00:46
This is the truss.
00:56
So, this is our truss.
01:07
So, there is the upward position is rvb.
01:13
There is the v point and there is the d point.
01:18
There is the c point.
01:22
There is the f point.
01:25
The angle between them is 45 degree and there is k, e, c.
01:44
So, there is downward is 10 km and the f is equal to 4 m and p2 a is 2 m.
02:08
Again the length is 2 m and the 5 km there is the height is 4 m.
02:21
This is the structure.
02:23
So, the first step is sum of all forces in 3 direction.
02:42
3 direction is equal to 0.
02:46
So, there is sigma f h is equal to 0.
02:50
So, there is 10 cos 45 degree minus rah is equal to 0.
03:03
So, rah is equal to 10 cos 45 degree rah is equal to 10 multiplying by 1 upon root 2.
03:18
So, rah is equal to 5 root 2 kn and the second step is sum of all the forces in y direction is equal to 0...
