🤓 Based on our data, we think this question is relevant for Professor Garcia's class at COLUMBIA.

Solution: A massless rod of length L has a mass m fastened at one end and a mass 2m fastened at the other end. What is the ratio of the moment of inertia about an axis through the mass m to the moment of inertia through the center of the rod? 1. 3/2 2. 4/3 3. 3/4 4. 2 5. 8/3 6. 3/8 7. 2/3 8. 1/2
