Consider the belt and pulley system in Fig 2.13. Inertias other than that shown in the figure are negligible. The pulley radius r = 0.1 m, and the motor inertia JM = 0.01 kg.m. Calculate the torque Tem required to accelerate a load of 1.0 kg from rest to a speed of 1 m/s in a time of 5 s. Assume the motor torque to be constant during this interval. ww M O JM Motor inertia Mass of load M r = Pulley radius Motor JM T FIGURE 2.13 Combination of rotary and linear motion.
