A motor drives a carrier mechanism with constant velocity w (see Figure 2.26). The path of point A should be such that at the lowest position the line AB is parallel to the horizontal conveyor, and at the highest position the line AC should be parallel to the inclined conveyor (so that the load can be transferred from one conveyor to another).
a. Find (by trial and error) such dimensions of the mechanism (for the assumed positions of the conveyor belts) that the needed trajectory of point A is achieved. (Hint: At extreme positions the motion of point A is reversed, which means that at these positions the links DC and CB are collinear.)
b. Animate the motion.
c. Plot the velocity and acceleration of point A over the cycle. What are the velocities and accelerations at the points of load transfer?
