Question
Consider Figure Q6, which shows a top-down view of a beam of length L =
2.5m and mass mb = 2 kg. The beam is of unifom density and hinged at its
centre. The centre of a disc of mass ma = 2 kg and radius R = 0.8m is
attached firmly to one end. A point mass of mp = 15 kg is attached to the
beam on the other side of the hinge. Calculate the required distance from the
hinge, I, of the point mass such that the radius of gyration, kG, of the entire
system is equal to L/4 (= 0.625 m).
