A drum of 80-mm radius is attached to a disk of 160-mm radius. The disk and drum
Question:
A drum of 80-mm radius is attached to a disk of 160-mm radius. The disk and drum have a combined mass of 5 kg and combined radius of gyration of 120 mm. A cord is attached as shown and pulled with a force P of magnitude 20 N. Knowing that the coefficients of static and kinetic friction on are μs = 0.25 and μk = 0.20, respectively, determine
(a) Whether or not the disk slides,
(b) The angular acceleration of the disk and the acceleration of G.

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.
