According to the parallel axis theorem, what is the moment of inertia of a body about point B?

1. I = I₀ + Md²
2. I = I₀ - Md²
3. I = Md²
4. I = I₀

Correct answer: I = I₀ + Md²

Solution

The parallel axis theorem states that the moment of inertia about any axis parallel to the center of mass axis is given by I = I₀ + Md², where I₀ is the moment of inertia about the center of mass axis, M is the mass of the body, and d is the perpendicular distance between the two axes.
