Disk B Weighs 52 Lb And Has A Centroidal Radius Of Gyration Of 8 9 In The Power Unit Consists Of A Motor Mand A Disk A 1 (22.89 KiB) Viewed 24 times
Disk B weighs 52 lb and has a centroidal radius of gyration of 8.9 in. The power unit consists of a motor Mand a disk A, which is driven at a constant angular speed of 1890 rev/min. The coefficients of static and kinetic friction between the two disks are y = 0.63 and k 0.49, respectively. Disk B is initially stationary when contact with disk Ais established by application of the constant force P = 3.4 Ib. Determine the angular acceleration a of B and the time t required for B to reach its steady-state speed. The angular acceleration is positive if counterclockwise, negative if clockwise. *9.7 in. = 11.4 in. Answers: a rad/s2 S
