In this problem, a bent strain pole supports a cable force f inclined at a 5 is to 12 slope.
00:11
Determine the moment at points b and a due to the applied force.
00:16
All right.
00:17
So this is a cable force, right? this is given to us.
00:24
Okay.
00:25
So now we want to calculate this angle.
00:28
Why? because we know 5 and 12, this is the ratio for the.
00:32
We have the, you can say the inclined, the slope is given to us.
00:38
Right.
00:39
So that means if this line, you can see this line and this line is parallel.
00:44
So we can say that this is same angle as this, right? so suppose this angle is alpha, right? are you getting my point? so when we calculate a moment, so force should be perpendicular to the distance, right? remember this.
00:59
So here force will be force...
