hi there. can anyone please explain to me the parallel axis theorem? the parallel axis theorem states that I = I_cm + M(d^2) where d = distance from the center of mass axis to the parallel axis and M is the total mass of the object. The rotational inertia of a thin rod about the center is = (1/12)M(L^2) and the rotational inertia of a thin rod about the end is = (1/3)M(L^2). Here is a picture I need you to use to explain to me the parallel axis theorem. i just don't see how inertia of the bar is (1.33m_bar)(l^2)/12
