Calculate the rotational inertia for each of the three arrangements.

Four point masses of 3.0 kg each are arranged in a square on massless rods. 

The length of a side of the square is 0.50 m. Consider rotation of this square about three different axes: 

(a) An axis passing through masses B and C; 

(b) An axis passing through masses A and C; and 

(c) An axis passing through the center of the square and perpendicular to the plane of the square
