Hello, I am somewhat new to this forum but have a basic question that I have had for a long time.
please excuse it if it is a dumb question.
I understand how centrifugal force works - you spin something around and it wants to fly away from the center.
And I understand that there are mathematics equations that explain this fairly well.
My question has to do with multiple centrifugal forces at once, and the only way I know how to describe what i am talking about is to describe an experiment - but I don't know what the outcome would be. Here goes.
If you took a motor with a long arm on it - say 4-5 feet, and spun it around at 30-40 RPM. the end of the rod would have centrifugal force pulling it away from the motor- let's call this the primary rod. What if you then put a smaller motor at the end of that primary rod with another rod on it also spinning (of course weighted properly so it wasn't unbalanced) it would also have its own centrifugal force acting on it call this the secondary rod. The problem is that now the 2 "fields" (for lack of a better term) of centrifugal force would be adding to each other and subtracting from each other with each revolution. And this is because the secondary rod would be swinging away from the primary motor half the time. (lets call this the first problem)
Now what if you added a third motor and rod and at the end of the third rod you had a sealed box with a ping pong ball inside. the question is, could you properly balance out the revolutions of the second rod so that the first problem was negated? could you ever have the centrifugal force from the first and third rod cancel each other out? Could you ever get the ping pong ball to not be squished up against the wall of the box, but rather sitting somewhere in the middle simply due to centrifugal force?
If you are still having trouble seeing what i am talking about, imagine a 6 foot pole with a motor in the middle. the pole had a motor at one end as well attached to it, and the other end has a weight. the motor on the end of the pole has a smaller pole on it with another small motor at the end of the smaller pole (and a weight at the other end.)
