Imagine a spinning disk of uniform density, with mass M and radius R. Except where noted, it is rotating about an axis through its center and perpendicular to its plane. What is its moment of inertia if the axis of rotation is moved to a line 2R from the center of the disk? (There’s no rotation of the axis, it remains parallel to its original position). Could someone explain what this question is asking in a diagram?
