Question

Learning Goal: To be able to use the equation for relative acceleration between two points to find unknown linear accelerations and angular accelerations of connected bodies. 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 1.25 m. When member ABC forms an angle of ? -39.00 with the rack, the acceleration of Bis ap 1.95 m/s2 and the velocity of the block attached at A is vA- 2.55 m/s in the direction shown Positive angular velocity and acceleration are in the counterclockwise direction.
