Determine the coordinate direction angles α, β, γ of the moment created by this force about point O, assuming that the force is 22 N.
I tried breaking the force into x and y components, then multiplying it by the cross product of the rAO distance vector, but whenever I try to find the scalar of that moment vector, the answer is a few hundred N*mm off. I don't know what I'm doing wrong. Please help
You have to also decompose the distance vector. It should be rAO=.2sin15i+.2cos15j. Did you do that?
