The 12-lb disk A has a radius us rA = 6 in. and an initial angular velocity
Question:
The 12-lb disk A has a radius us rA = 6 in. and an initial angular velocity ω0 = 750 rpm clockwise. The 30-lb disk B has a radius rB = 10 in. and is at rest. A force P of magnitude 5 lb is then applied to bring the disks into contact. Knowing that μk = 0.25 between the disks and neglecting bearing friction, determine
(a) The angular acceleration of each disk,
(b) The final angular velocity of each disk.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
