https://en.wikipedia.org/wiki/Balancing_of_rotating_masses See the image in that page. I know intuitively why a direction of torque is counterclockwise-because of a centrifugal force. But an direction of angular momentum of that shaft with attached weights (ignore the shaft mass) is southeast direction. And a torque of that body is an inward of page, which means clockwise direction. Why I gets this conclusion???? somebody help me.
