Document Summary
Freely rotating bodies i: when a body is airborne, it is not possible to apply reaction forces. Axes of rotation: axis of rotation for each component of the rotation must pass through the center of mass. So long as segment motions are symmetrical, angular momentum in each plane will be constant: otherwise, angular momentum can be transferred between planes. Radius of gyration: completely under our control, a bigger radius of gyration leads to a smaller angular velocity, a smaller radius of gyration leads to a bigger angular velocity. Generating angular momentum: any angular momentum generated in one segment is counteracted by the opposite angular momentum in the remaining segments, the angular momentum while airborne is generated at take off.
