I know that the g goes up with radius and rotation speed, but I can't
find it in just that way. When I look it up, it is about angular
momemtun. Can you tell me the formula for the extra g as a product of
radius and revolutoins per second?
Also, What's the TOTAL gravity at the rim of a disk that is rotating
flat at ground level? In other words, the spin pulls outward at ?? g's
and the Earth pulls downward at 1 g, how many g's does a bug on the
rim feel?
Did this take algebra or trig or calculus? Or did you just look it
up?
