4. (30 points) 2D Equilibrium. Dr. Flowers was finishing his workout with slow arm curls using a 30 lb weight as indicated in the figure. The brachialis muscle group (biceps muscle and brachialis muscle) is the major force generator in this exercise. The muscle group can be approximated as a single tensile force oriented from a point on the ulna to a point on the humerus. Those attachment points are 2" to the right of the elbow joint (E) and 8" above the elbow joint (E), respectively. The forearm (from E to the finger tips) has a weight of 3.2 lb that acts at point G a. The elbow joint at E is most appropriately approximated as what type of support reaction? b. Draw the compete FBD needed to solve this problem. c. Solve for the support reactions at E and the magnitude of the force, F. generated by the brachialis muscle group.
