qu.2.1.question=Masses <i>m</i><sub>1</sub> and <i>m</i><sub>2</sub> attached to a massless rod rotate about point <i>O</i> in a horizontal plane.  Calculate the angular acceleration of the system if the torque applied to it is equal $torque N-m, <i>r</i> = $r m, <i>m</i><sub>1</sub> = $m1 kg, and <i>m</i><sub>2</sub> = $m2 kg.  Give the answer in <i>rad/s<sup>2</sup></i>.
