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 2.40 m and the distance between A and B is 1.25 m. When member ABC forms an angle of 0 = 37.0° with the rack, the acceleration of B is ag = 1.55 m/s² and the velocity of the block attached at A is A = 2.95 m/s in the direction shown. Positive angular velocity and acceleration are in the counterclockwise direction. (Figure 1)

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 2.40 m and the distance between A and B is 1.25 m.
