Homework Statement
Determine the magnitude of the projected component of F along AC. Express this component as a Cartesian vector.
Homework Equations
Information I'm working with.
The Attempt at a Solution
Most of my attempts have proven fruitless.
I understand that in order to find a component of F along AC we'd need to have the Uac but I'm just having difficulty finding the cartesian coordiantes for segment AC.
Cosine law comes to mind but how would you apply cosine law in cartesian for a 3D image?
Also, do the signs for the cartesian coordinates of AC become times by a (-1) as the force is protruding outwards from point C?
Any help is much appreciated. I've been stuck on this question for a good 5-6 hours now.
Thanks!
