Pendulums ~ period of oscillation

[brownie24]

Homework Statement

A pendulum is made of 2 disks, each of mass M and radius R separated by a massless rod. one of the disks is pivoted through its center by a small pin. The disks hang in the same plane and their centers are a distance L apart. Find the period for small oscillations.

Homework Equations

T = 2pi/omega

The Attempt at a Solution

I honestly haven't a clue how to start the problem. I am having trouble even visualizing it. Can anybody clarify what the question is?

Find the period of small oscillations...? Anything more is given?
I don't see any oscillations there..
