PLEASEE HELP
A solid circular disk has a mass of 4.59 kg and a radius of 0.389m. Each of three identical thin rods has a mass of 0.757 kg. Therods are attached perpendicularly to the plane of the disk at itsouter edge to form a three-legged stool (see the figure). Find themoment of inertia of the stool with respect to an axis that isperpendicular to the plane of the disk at itscenter. (Hint: When considering the moment of inertia ofeach rod, note that all of the mass of each rod is located at thesame perpendicular distance from the axis.) PLEASEE HELP

Explanation / Answer

   the moment of inertia of the stool will be the sum ofmoment of inertia of circuilar disk and the    moment of inertia of the three cylindricallegs    the moment of inertia of the circuilar disk willbe    Idisk = (1/2) m r2    the moment of inertia of the cylindrical leg willbe    Ileg = m r2    so the the moment of inertia of the stool willbe    Istool = Idisk + 3(Ileg)            = ........... kg.m2    hope you got it    hope you got it
