- Two blocks are connected by an ideal string, which passes over a pulley without slipping (see figure). The magnitudes of the wire voltages applied to blocks 1 and 2 are represented, respectively, by T1 and T2. Consider T2>T1. In this case, the pulley rotates counterclockwise. The pulley has radius R=0.10 m and rotates around an axis perpendicular to its surface passing through its CM. The CM of the pulley coincides with its center. The pulley's moment of inertia about the axis of rotation is denoted by I and its angular acceleration is α=0.50 rad/s2. If T2=87 N and T1=50 N, determine I (in kg⋅m2).
