Angular Frequency for Small Oscillations

In summary, the conversation discusses a homework problem involving a uniform disk suspended from a pivot and the need to find the angular frequency for small oscillations. The solution is found by using the formula w=square root of mgd/I, where m is the mass of the disk, g is the acceleration of gravity, d is the distance from the pivot to the center of mass, and I is the moment of inertia. The individual asking for help initially does not understand the concept, but later realizes the solution on their own.

[SOLVED] help with homework problem

Homework Statement


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.

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.

never mind. i figured it out. my professor didn't cover it yet but I looked it up. w=square root of mgd/I
