## How to get mag. & angles of resultant couple moment

I have another thread for another problem, but no one seems to be responding about this second problem, so i'll post it here.

Need to find the magnitude and direction/space angles of the resultant couple moment of two valve handles being turned, as pictured:

Would the resultant mean at the origin of the axes? So far, I've done this, using the left as A and the right as B:

M=(d)(F)
MA=(0.175m)(35N)=6.125Nm
MB=(0.175m)(25N)=4.375Nm

Should the forces have unit vectors k on them? If what I did is somewhat right, then how do I get the resultant magnitude and direction if the only other piece of data given is that the wheel on the right is angled 60deg. from the y-axis--no other distances, etc?
 Mentor Blog Entries: 1 Your magnitudes are correct, but these moments are vectors. What direction do they point? ($\vec{M} = \vec{r} \times \vec{F}$) Add those vectors. (And please don't post the same question in mutliple threads! It's generally best to post one problem per thread.)
