Algodoo

The author is Villard de Honnecourt, the principle is based on the imbalance of forces - at the beginning of the movement the left part of a circle is loaded more than the right one, the left side torque forces will be greater than the torque on the right side and the wheel will begin to rotate. The fixed hammers will be tipped in the top position in the gravitational field and according to the author’s presumption they will turn around by their strikes. We will be convinced by the Phun that even we remove friction and air resistance, the wheel always stops in position with four hammers down and three ones up.
