**1. Homework Statement**

Using masses, springs a stop watch and ruler, determine the location of the center of mass and mass moment of inertia about an axis passing through the center of mass of a bicycle crank.

**3. The Attempt at a Solution**

I've been staring at this problem for a while now and I have no idea where to start. Any help would be much appreciated. I have included a link with what the bike crank looks like.
