I'd like to figure out the moment at pt A using the scalar approach, not vector
M = r x f
M = fd
The Attempt at a Solution
I think I might be missing some concept that would make my life easier...
I figured out how to do this by vector. But I am confused as how to do this by scalar.
for the couple at the top,
My = (2)(2) = 4 j
and then theres a moment at d which causes a rotation in the x axis
Mx= 5 i
The 10kN force can be solved if i put a matching 10kN going up and down at pt A, and then the 10kN pointing down at A and the 10kN pointing up at E would be a couple. However, if I do that the moment calculated is not strictly in one axis.
Kind of confused, I have a feeling im approaching this wrong.
