... from a long wire. Its period Ta of angular SHM is measured to be 2.53 s. An irregularly shaped object, which we call object X, is then hung from the same wire, as in Fig. b, and its period Tb is found to be 4.76 s. What is the rotational inertia of object X about its suspension axis? Answer: The rot ...
