Hello, I am trying to make something that spins out of balance. currently my current weighs are half circle in shape. I know that if I change the profile of the weights to a pie shape (less than 180deg semi circle) the center of mass moves away from the axis of rotation, but at the same time my mass is decreased (given same radius and thickness). Does anyone have the formulas that would help me optimize this? I am trying to reduce the overall radius of the spinning object for sizing and thought this might be the correct approach. Thanks hopefully.
