For one revolution of driving wheel W of the pusher and pick-and-place mechanism in Figure P4-6, find the horizontal stroke of the pushers for the portion of their motion where their tips are above the top belt. Express the stroke as a percentage of the crank length AB. What portion of a revolution of the driver crank AB does this stroke correspond to? Also find the total angular displacement of link DE over one revolution of wheel W. Scale the drawing for all necessary dimensions.
