A thin uniform rod of length 3L and mass M is bent into an L-shape, such that one leg has length L and the other has length 2L (the legs are perpendicular to each other). 1. Find its moment of inertia about an axis perpendicular to its plane and passing through the corner where it bends. 2. Find its moment of inertia about an axis perpendicular to its plane and passing through the midpoint of the line connecting the two ends. Hint: break the L-shaped piece into two pieces.
