The Load L Is Lowered By The Two Pulleys Which Are Fastened Together And Rotate As A Single Unit. For The Instant Represented, Drum A Has A Counterclockwise Angular Velocity Of 5.9 Rad/Sec, Which Is Decreasing By 3.2 Rad/Sec Each Second. Simultaneously, Drum B Has A Clockwise

The load L is lowered by the two pulleys which are fastened together and rotate as a single unit. For the instant represented, drum A has a counterclockwise angular velocity of 5.9 rad/sec, which is decreasing by 3.2 rad/sec each second. Simultaneously, drum B has a clockwise angular velocity of 3.6 rad/sec, which is increasing by 5.3 rad/sec each second. Calculate the accelerations of points C and D and the load L.
