Cover ABCD for an opening in the roof is hinged at corners A and B. The roof makes a 30° angle with the horizontal, and the cover is held in a horizontal position by brace CE. The cover's center of mass is at the centroid of rectangle ABCD and the cover weighs 200 N. a) The force that the brace exerts on the cover acts along the line from E to C. Determine the magnitude of the force that the brace exerts on the cover. b) Determine the reactions at the hinges. Assume that the hinge at B does not exert any axial thrust. The solution to this problem must include a free-body diagram of the cover.
