In previous question, if the student standing on a table (at rest) free to rotate about its central axis holding a rotating disc with smooth handles attached to its central axis of rotation. Initially he keep the axis of disc vertical such as the disc is rotating in a horizontal plane. What happens if he tilt the axis of rotating disc by \( 90^{\circ} \) to make the disc to rotate in vertical plane. Explain the concept in the problems.
