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 and kinetic diagrams for bar AB, which is supported by a frictionless pin at A and a frictionless roller at B and determine the magnitude and directions of the horizontal and vertical pin reactions at A and the normal force exerted by the surface on the roller at B. ignore the mass and size of the roller at B.
