Moment of inertia about the center of a disk:
Moment of inertia about a parallel axis:
Where d is the distance from the center of mass.
Icm = (1/2)mr2 = (1/2)(21 × 10-3)(0.062)
Calculating Moment of inertia: A 12-cm-diameter CD has a mass of 21 g.
What is the CD'S moment of inertia for rotation about a perpendicular axis
a) through its center and
b) through the edge of the disk.
