A drum of 80-mm radius is attached to a disk of 160-mm radius. The disk and drum have a combined mass of 8 kg and a combined radius of gyration of 120 mm. A cord is attached as shown and pulled with a force P of magnitude 20 N. Know that the coefficients of static and kinetic friction are us= 0.25 and uk = 0.2, respectively. P Determine the angular acceleration of the disk. (You must provide an answer before moving on to the next part.) rad/s2.
