Homework Help: Help with homework problem

  1. Oct 26, 2007 #1
    [SOLVED] help with homework problem

    1. The problem statement, all variables and given/known data
    A uniform disk of radius 4.4 m and mass 9 kg is suspended from a pivot 1.364 m above its center of mass. The acceleration of gravity is 9.8 m/s^2. Find the angular frequency w for small oscillations.

    3. The attempt at a solution
    I'm just wondering what does this question mean by finding the angular frequency for "small oscillations." Any help will be appreciated. Thanks!

    physical pendulum

    If pushed slightly to one side, the disk would oscillate like a pendulum.
