Hi, I have a question about rigid body rotation. If I have a rod out in space in free float and I attach a battery powered fan to center of mass and then the fan is turned on to spin in a clockwise direction, then the rod should spin in a counterclockwise direction. This much I understand. But, what if, instead, the fan was attached to the end of the rod rather than to the center of mass? What would happen then? Any help would be greatly appreciated!
