So I have found the unit vector [itex]u_{ab}[/itex] now I am stuck as to what to do.
I need to find the projected component of the 80 N force along the line axis AB of the pipe.
I have the coordinates of B and A as well. But I am a little lost now.
Any hints are appreciated.
Thanks,
Casey
Also I am having trouble reading the diagram...I have A at [itex]r_A=6i+7j-2k[/itex] meters...does that look right to you?
