Question

3.(10 points) Design a four-bar linkage for two rocker positions. The finish angle for the input link is 30° from the horizontal, and the finish angle for the output link

is 30° from the ground link as shown.When the input link O2A turns counter-clockwise 80°, the output link O2A turns counter-clockwise through 70°. Suppose we know that the base link is 2.2 in and the coupler link is 3.5-in long. a) Please use the GCP approach to determine the lengths of the input link and output link.Write your answer in the table below. b) Submit a screenshot of the final drawing with dimensions of the unknown link lengths.
