Okay, i want to draw the free body diagram for the beam.
00:04
So, you know, at the left end, we have the tension in the rope.
00:20
We're told this is 30.
00:24
All right.
00:24
Then at this point, we have our applied force.
00:37
That angle is also 30.
00:41
And then at b, we have actually two components like that.
00:58
And then, so this is point a over here.
01:02
All right, so what we want to do is find out what t, the tension in the rope, and what bx and by are.
01:19
All right, so let's write out our force equations, the x and y directions.
02:05
All right...
