How might you determine experimentally the moment of inertia of an irregularly shaped body about a given axis?
Alex73 [517]

Answer:

Using the parallel axis theorem

Explanation:

We note the angular speed and also the systems energy. Using these information we calculate the moment of inertia of irregular shaped body.

Io = 2E/w²

When we have moment of inertia of irregular shaped body, we can then use parallel axis theorem to solve for the moment of inertia of the body about the given axis.

I = Io + md²
