Disk A has a mass of 8 kg and an initial angular velocity of 480 rpm clockwise;
Question:
Disk A has a mass of 8 kg and an initial angular velocity of 480 rpm clockwise; disk B has a mass of 4 kg and is initially at rest. The disks are brought together by applying a horizontal force of magnitude 30 N to the axle of disk A. Knowing that μk = 0.15 between the disks and neglecting bearing friction, determine
(a) The angular acceleration of each disk,
(b) The final angular velocity of each disk.

Angular movements are produced when the angle between the bones of joint changes. There are several different types of angular movements, including flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. The extension is the opposite of flexion in that the angle between the bones of a joint increase.
