. Conservation along the horizontal using a bicycle wheel: Stand on the platform holding a bicycle wheel with its axis horizontal with your arms fully extended. While holding the platform stationary, let a colleague spin the wheel. Release the platform then turn the wheelâs spin axis "up." Observe the platform turn with a âdownâ spin vector, Ď. Return the wheel to the starting position and the platform should stop. Turn the wheelâs spin axis "down." Return the wheel to the starting position. Describe the platformâs reaction in terms of conservation of vertical angular momentum: Use L1 as the angular momentum of the person and the platform, and L2 as the wheelâs angular momentum. Use vector diagrams to show how the vertical angular momentum of the system, Ltotal = L1 + L2, starts at zero and remains zero throughout the exercise. That is, show that L1i + L2i = L1f + L2f.
