The masses and coordinates of four particles are as follows: 27 g, x = 2.0 cm, y = 2.0 cm; 16 g, x = 0, y = 4.0 cm; 43 g, x = -3.0 cm, y = -3.0 cm; 61 g, x = -2.0 cm, y = 4.0 cm. What are the rotational inertias of this collection about the (a) x, (b) y, and (c) z axes?
I'm not sure.. would I use parallel axis theorem?
