We haven't gone over cross products. But if it's pertinent I would like to learn more about it even if just for the sake of being prepared for future labs or higher level classes. I have class tomorrow night and I'll ask my professor about the right hand rule and cross products. Links would...

We haven't gone over cross products yet. We've done resolving force vectors with trig.

I fixed it

That's what I got after doing a bit of research. Sorry the first one spazzed out.

Ok I'm going to have to do some research. The right hand rule and position vectors is new for me. I'll post what I come up with later tonight.

The idea was to achieve rotational equilibrium. Really I'm just not sure if I've included everything, or if I'm representing the experiment properly.

Not specifically but if I'm understanding you correctly, do you mean the force multiplied by the moment arm? If so, it was 73.5g(33cm). Which I converted into Newton meters and I got .2379Nm.
