Two identical rotors: movable masses at rod ends (left) and at half distance (right), each with hanging block.
Two identical rotors: movable masses at rod ends (left) and at half distance (right), each with hanging block.
The rotating systems, shown in the figure above, differ only in that the two identical movable masses are positioned a distance \(r\) from the axis of rotation (left), or a distance \(\dfrac{r}{2}\) from the axis of rotation (right). What happens if you release the hanging blocks simultaneously from rest?
