• Two balls with masses M and m

  For an axis of rotation perpendicular to the rod, show that the system has the minimum moment of inertia when the axis passes through the center of mass.

• Center of Mass and Moment of Inertia

  These axes are parallel to each other and perpendicular to the rod. The moment of inertia of the two-mass system about axis a is I_a, and the moment of inertia of the system about axis b is I_b.
