Problem 3.18 A small ball A of mass mis con- nected to a vertical shaft at O by a string of length I. The system is initially at rest, with the pendulum in contact with the shaft. The shaft is then slowly set in rotation to reach a constant angular velocity w. Neglect the size of the balls and the diameter of the shaft, that is, O is on the axis of the shaft. a. Show that the line OA...

The crank OA rotates in the vertical plane with a constant clockwise angular velocity
The crank OA rotates in the vertical plane with a constant clockwise angular velocity ωo=4.5 rad/s. For the position when OA is horizontal, (a) determine the angular acceleration of the uniform 10 kg slender bar AB and the horizontal and vertical components of the acceleration of its center of mass. Use the methods of kinematics (Ch 16) to establish both the magnitude and direction → or ← for aG and; CW or CCW for αAB) of each variable. (b) Draw complete free body...
