Question: A solid disk of radius, R = 0 . 0 6 3 m , and mass, M = 0 . 5 0 0 kg ,

A solid disk of radius, R =0.063 m, and mass, M=0.500 kg, has a small hole drilled through it halfway between its center and outer edge. Determine the moment of inertia for the disk about its centre of mass? Determine the moment of inertia of the disk about the stated ?( kgm2).(Hint: use parallel axis theorem.) Using a free-body diagram, with the weight of the disk acting at its center of mass, determine the torque on the system about the axis and determine, using similar arguments as were used for a pendulum for the class notes, the constant k for the linear restoring torque in this case. The effective spring constant is: ?(kgm2/s2) The effective mass of the system will be the moment of inertia about the axis which you have already calculated above. Your work above should establish that the system executes SHM with the angle theta as the variable rather than the displacement, x, as was the case for the spring motion we studied in class. Use the similarity of this analogous system to follow the same steps as were used in class to get the angular frequency of a pendulum and determine the period that the system will oscillate through ?
