Say we have a motor attached to the Earth with gear A, that drives identically sized gear B. Gear B spins on its own axis and but is also attached to ground. Torque between gears is equal.
Technically each gear has equal but opposite AM right, but If I take Earth into account, how is Ang. Momentum conserved?
Which axis do I use? Axis of A or B?
I understand AM for simple problems, but this got me thinking. Maybe this is a bad example and requires clarity so please let me know.
Thank you
