How to start moment couple problems

[Doc Al]

Not sure what you are doing with the angles. Both moments act in the x-y plane, so there shouldn't be any $\hat{k}$ involved. The first moment acts in the -x direction ($- \hat{i}$); the second moment is at a 60 degree angle to the x-axis (find the components of that vector: it will have both an x and a y component).

...yeah, I realized that after I stared at it for a while.

Thanks again for ALL the help. My internet died around 2:30pm yesterday so I couldn't get back on at all until this morning, so I basically had to stare at it for a while, ask a few people--and am pretty sure I got it.
