.. 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 µs = 0.25 and µk = 0.2, respectively. Does the disk slide or just roll without sliding? What is acceleration of the disk?

Table 3 shows the process sequence in a production line and its related direct time study data. The production process must follow a specific route of processes A, B, C, and D respectively. Task A is in full automatic mode and requires one operator at the workstation. The worker at task B was rated with 90%, the worker at task C was rated with 115% and the worker at task D was rated with 80%. The standard allowances accepted by the company are 6% for fatigue, 5% for personal, and 4% for delay. The normal operating period is 8 hours per day and 24 days per month. Analyse the given information and determine the standard time for the product in minutes.
