i need to find the moment of inertia of this figure(adsbygoogle = window.adsbygoogle || []).push({});

http://s93755476.onlinehome.us/stuff/knight.Figure.13.54.jpg [Broken]

and express my answer in terms of M, L, m_1, and m_2.

i tried using the parallel axis theorem using (1/12)ML^2 since it is a thin rod with the axis of rotation about the center but im not sure what to use for Md^2. in I = I_cm + Md^2.

i was thinking maybe I = (1/12)ML^2 + (m_1)(1/2L)^2 + (m_2)(1/4L)^2. but it didn't work.

any help is appreciated.
