A 40 Kg Disk Of Radius R 250 Mm Spins At The Constant Rate 0 80rad S With Respect To The Bent Axle Abc Which Has A Ne 1 (83.51 KiB) Viewed 13 times

A 40 kg disk of radius r=250 mm spins at the constant rate 0 = 80rad/s with respect to the bent axle ABC (which has a negligible mass) as shown in Figure 2. The system was at rest before the couple M, is applied. The couple M, is applied for 3 seconds, as shown, and then removed. If the angular velocity reached by the bent axle after 3 seconds from the time couple M, was applied, is 2.4 rad/s, determine a) The dynamic reaction at the support at point A after 3 seconds (just before the couple M, was removed). - b) The angular acceleration of the disk after 3 seconds (just before the couple M, was removed). - c) The kinetic energy of the system after 3 seconds (just before the couple M, was removed).
