There are three objects rotating as depicted below. The first is a cone rotating about an axis through its middle. The second is a rod rotating along one edge, the third is a wide board, also rotating about an edge. All objects have the same mass and extend the same distance from their respective axises. #1 #2 #3 Which of the following is a correct ranking of the rotational inertia for the three objects?
