[问答题]
An Atwood’s machine con.s ;fu7jgi: 87 x7hmr +jvuzihsists of two masdv.ha* br6woa ak+:w t;mv,-wojrcj 3 /m(3rvses, $m_1$ and $m_2$ which are connected by a massless inelastic cord that passes over a pulley, Fig. 8–47. If the pulley has radius R and moment of inertia I about its axle, determine the acceleration of the masses $m_1$ and $m_2$ and compare to the situation in which the moment of inertia of the pulley is ignored. [Hint: The tensions $F_{T1}$ and $F_{T2}$ are not equal. We discussed this situation in Example 4–13, assuming for the pulley.]
