Member ABC is controlled using a rack and pinion, which is connected at B. (The rack is the long, horizontal gear.) The rack can only move horizontally and the pinion does not translate. A block in a sleeve is connected at A and allows movement only in the vertical direction. Member ABC has a total length of 2.30 m and the distance between A and B is 1.15 m . When member ABC forms an angle of =33.0 with the rack, the acceleration of B is aB=1.95 m/s2 and the velocity of the block attached at A is vA=3.15 m/s in the direction shown. Positive angular velocity and acceleration are in the counterclockwise direction
