true, my mistake. Mass is different than weight. And rotational inertia is
determined by mass, speed, and distance from the axis, however, gravity
DOES play a roll in rotating objects, as long as the axis is not
perpendicular to the pull of gravity. So unless the crank is straight up
and down, gravity will effect the motion of a rotating mass, to a lesser
extent as rpm increases. Just think of a huge imbalanced weight on a swing
arm. If it's not going 5000rpm, it will rotate slower on the up stroke than
the down stroke.
