An atwood’s machine consists of two masses, Ma and Mb, which are connected by a massless inelastic cord that passes over a pulley. If the pulley has raiud R and moment of inertia I about it axle, determine the acceleration of the masses Ma and Mb, and compare to the situation in which the moment of inertia of the pulley is ignored. The tensions are not equal. I=0 for the pulley.
