Angular velocity and angular acceleration of bar AB ngular shown in the figure are and , respectively. Dimensions of the rectangular plate are 12 in x 24 in. What is the angular velocity of the rectangular plate? 2. The cylindrical disk shown rolls on the fixed cylindrical surface with a constant clockwise angular velocity of 1 rad/s. Find the accelerations of points A and B in Cartesian–vector form. 3. Angular velocity and angular acceleration of bar AB shown in the figure are figure are and , respectively. Find the acceleration of point D in Cartesian-vector form. vector 4. Each of the two blocks has a mass m. The coefficient of kinetic friction at all surfaces of contact is µ. If a horizontal force P moves the bottom block, determine the acceleration of the bottom block in both cases shown. 5. Determine the acceleration of the 8-kg collar A along the bar if the coefficient of kinetic friction between the the collar and the bar is µk = 0.1. 6. The two 100-lb blocks are released from rest. The coefficient of kinetic lb friction of all contacting surfaces is µk = 0.1. How long does it take block A to fall 1 ft? ...
