Now here we are asked to find the magnitude of the talk about a point p here of a force, right? so to find the talk, what we need to do is basically to find the distance over this point p to this force line, right? so basically we are asked to, we first need to find this distance here, right? that's what we need to find.
00:28
So when you find that distance.
00:30
And so basically this is 30 degrees, as we know, right? and the distance of this, can be obtained, i think there are, of course, there are several ways to obtain this distance.
00:40
We have, we see that it basically has two, we can separate this distance in two parts, right? one is this part and the other is this last part, right? so let's look at for this part first.
00:53
And the first part, and of course that's given by, you know, because this is 30 degrees and you can see this is also 30 degrees, right? is 30 degrees.

And then of course, this side, you know, that is four feet, right? and this side is four feet...
