    After drawing it out and thinking about it, it seems that things cancel out.

    |dw:1433730534260:dw| I was wondering is something like this would result in some sort of upward force.

    For the arrows mixed up.

    So is this the right picture then? |dw:1433730753297:dw|

    Hmmm, I keep confusing myself with orientation

    They're spinning in opposite directions.

    I'm wondering, since they both balance on the beam, is there still procession from gravity?

    Well precession is a change in the angular momentum vector which is torque, so maybe we can work it out with some math, I'm not really sure what to do yet but I'll spit out what equations I know. \[\large \bar \tau = \frac{d \bar L}{d t} \] \[\large \bar L = \bar r \times \bar \omega\] \[\large \frac{d \bar L}{dt} = \frac{d \bar r}{d t} \times \bar \omega + \bar r \times \frac{d \bar \omega}{dt}=\bar r \times \bar \alpha = \bar \tau\]

    Hmmm that doesn't seem quite right I think I've left somthing out

    So procession is a torque that is done in reaction to a torque on the axis of rotation?

    Are you confusing angular velocity with angular momentum?
