quote [ Simply put, it is a novel arrangement that has a linear action of a mass escaping a rotating wheel while the centrifugal force acts upon the remaining liquid mass to maintain balance, thereby converting the expected linear reaction of imbalance into an angular (rotational) reaction of decreased wheel speed. ]
Finally built and tested. It works.
I admit it's odd to me.
Centrifugal balancers(LeBlanc Balance) have been around for almost a hundred years using the "outside acceleration" of the centrifugal force. We've known since Newton that the first two laws of motion and Conservation of Momentum don't behave as expected/apply in non-inertial systems(where there is an outside source of acceleration). And we've known just as long that an inertial release from a spinning object has a reaction caused by the sudden change in mass distribution relative to the axis of rotation. And yet ... combining these facts in one demonstration unit causes cognitive dissonance. It's a truly odd situation

Centripetal force is NOT the force that "pulls you towards the outside", it's the force that causes the thing to move in a circular pattern. For example, swinging a rock on a string, the centripetal force is the tension in the string that keeps the rock from flinging away. To use something more individual, you're riding a carousel. You're stupid human body thinks that you're being pushed outward from the center, but that's not the case. If you were to be released from the carousel, you'd move in a straight line tangent to the circular arc you were previously on. The centripetal force that you're feeling is the friction keeping you in your seat, which is actually acting towards the center of the carousel, not away. Friggin' psychics quacks.
Missed you, by the way! Glad you're back!
