Four point masses of 3. each are arranged in a square on massless rods. The length of a side of the square is d=0.

Four point masses of 3.6 kg. each are arranged in a square on massless rods. The length of a side of the square is d=0.34. What is the rotational inertia for rotation about an axis passing through masses A and C? What is the rotational inertia for rotation about an axis passing through the center of the square and perpendicular to the plane of the square?
