WebWhat is the moment of inertia of the disc about an axis passing through its edge? A) 0.08 kg m2 B) 0.16 kg m2 C) 0.24 kg m2 D) A solid flat disk of mass M = 4.0 kg and radius R = 0.20 m is rotating about an axis passing through its center as shown in the right figure. WebRecall that the moment of a dusk rotated around the axis through the center of mass normal to the disk is I_N= 1/2 MR^2, and the moment of the disk rotated around an axis through the center of mass in the plane of the disk is I_p = 1/4 M R^2.
