## Homework Statement

I'd like to figure out the moment at pt A using the scalar approach, not vector

## Homework Equations

Vector

M = r x f

Scalar

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,

M

_{y}= (2)(2) = 4

**j**and then there's a moment at d which causes a rotation in the x axis

M

_{x}= 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 I am approaching this wrong.
