Period of Pendulum: Spinning Disk Forces & Inertia Moment\

[QUOTE="LCSphysicist, post: 6336486, member: 675151"] [B]Homework Statement:[/B] Find the period of a pendulum consisting of a disk of mass M and radius R fixed to the end of a rod of length l and mass m.How does the period change if the disk is mounted to the rod by a frictionless bearing so that it is perfectly free to spin? [B]Relevant Equations:[/B] t = r*f = I*theta If the bottom disk is free to spin, will it necessarily spin? all the forces in this disk don't produce a torque. I don't know why we disregard it's inertia moment when it is free to spin (It's intuitively set, but I can't see it mathematically) :\ [/QUOTE]
