Question:

Four small spheres each of which you can regard as a point of mass 0.200 kg, are arranged in a square 0.400 m on a side and connected by extremely light rods (Fig. 9.29). Find the moment of 0 inertia of the system about an axis
(a) Through the center of the square, perpendicular to its plane (an axis through point 0 in the figure);
(b) Bisecting two opposite sides of the square (an axis along the line AB in the figure);
(c) That passes through the centers of the upper left and lower right spheres and through point O.
