A thin rod of mass M and length a rotates horizontally about a fixed vertical axis through O with angular velocity Ω. A thin disc of mass M and radius a/4 is pivoted on the rod with its centre a/4 from the free end and rotates about its own vertical axis with angular velocity 4Ω. The total angular momentum about O is (nMΩa²)/48. Find n.
