A uniform thin rod of mass M = 3.47 kg pivots about an axis
through its center and perpendicular to its length. Two small
bodies, each of mass m = 0.223 kg, are attached to the ends
of the rod.
What must the length L of the rod be so that the moment of
inertia of the three-body system with respect to the described
axis is I = 0.841 kg.m²?
