Question
The structure shown in the figure is formed by a uniform ring of
mass M = 1.4 kg and radius R = 20.0 cm that has particles of
mass m = 90 g attached to its periphery. The hoop is welded to
a uniform metal rod m of mass M and length L = 4R. The
arrangement can rotate with respect to an axis perpendicular
to the plane of the sheet that passes through point O located in
the middle of the rod. Calculate the moment of inertia of the
ring-particle-rod system.
