Consult Multiple-Concept Example 10 to review an approach to problems such as this. A CD has a mass of 17 g and a radius of 6.0 cm. When inserted into a player, the CD starts from rest and accelerates to an angular velocity of 23 rad/s in 0.31 s. Assuming the CD is a uniform solid disk, determine the net torque acting on it.Asolid circular disk has a mass of 3.26 kg and a radius of 0.379 m. Each of three identical thin rods has a mass of 0.239 kg. The rods are attached perpendicularly to the plane of the disk at its outer edge to form a threelegged stool {see the gure). Find the moment of inertia of the stool with respect to an axis that is perpendicular to the plane of the disk at its center. (Hint: When considering the moment of inertia of each rod, note that ail of the mass of each rod is located at the same perpendicular distance from the axis. ,1
