Okay, so the question here is asking us to determine the x and y components of each force vector shown in a diagram so we'll start just by drawing that diagram out give us a good idea should be vertically up, but i think you get the idea got three forces acting and they look roughly like this and the information we're given this is on some sort of horizontal surface and we've got a vector n which is s on c, we've got f, which is p on c, and f here, which is e on c.
00:49
Now, it doesn't really matter what these different things are.
00:53
We're just concerned about the values and the x and y components.
00:57
So this is 250 newtons, the vertical one.
01:01
This one here is 200 newtons, and this one, 150 newtons.
01:08
So for the x and y components, let's just write out what we've got here.
01:13
So we'll start with n s on c, and then we'll have f p on c, and then we'll have f e on c.
01:28
Again, not concerned about these labels.
01:31
Let's make that a c.
01:33
Right, and we've got an x component and a y component that we need to figure out.
01:39
We're starting with this vertical vector here as it's acting vertically upwards and we've got x in this direction and y in this direction...
