A solid circular disk has a mass of 1.2 kg and a radius of0.13 m. Each of three identical thinrods has a mass of 0.18 kg. The rodsare attached perpendicularly to the plane of the disk at its outeredge to form a three-legged stool (see the drawing). Find themoment of inertia of the stool with respect to an axis that isperpendicular to the plane of the disk at its center. (Hint: Whenconsidering the moment of inertia of each rod, note that all of themass of each rod is located at the same perpendicular distance fromthe axis.)
