Problem #11 (20 points): A uniform, rectangular plate is held in equilibrium by hinges at A and B and by cable EF. Both hinges are properly aligned along the y-axis and exert only force reactions on the plate (i.e. no reaction moments). Additionally, the hinge at B allows motion along the y-axis. The plate has a weight of 75 lb, which acts at point H. Also, the tension in the cable is 49.5 lb. Coordinates for the points are: A = (0, 4, 0); B = (0, 34, 0); E = (20, 30, 0); F = (0, 38, 25); and H = (10, 19, 0) in. x Z 4 in. F A B 4 in. 25 in. H E 30 in. 20 in. y 8 in. Find the reactions at points A and B. You must include a correct FBD to receive full credit.
