Now, sadly, at least initially, i don't know that drawing this is going to help.
00:07
I see, i'm going to try to figure out the component form of f.
00:16
So first of all, i know that f is 600 newtons.
00:24
But i want the f vector.
00:28
So in the x direction, i see that that vector is going from point e up to point b.
00:46
So in the x direction, that is 2 plus 2 more.
00:58
So that's 4.
01:00
So negative 4i.
01:05
In the y direction, it's also going negative.
01:10
And it's just going back three.
01:17
And in the z direction, it's going upward for sure.
01:24
So it's going to be positive.
01:28
And upward is two.
01:31
And it looks like that's all it is.
01:39
So the f vector is f times the u vector over u.
01:48
So let's put that into a calculator.
01:55
600 newtons times negative 4 in the numerator over the square root, 4 squared, plus 3 squared, plus 2 squared.
02:13
That gives me negative 446...
