Two couples act on the frame. If d = 4 ft, determine the resultant couple moment. Compute the result by resolving each force into x and y components and (a) finding the moment of each couple (Eq. 413) and (b) summing the moments of all the force components about point B. 2 ft B A y 1 ft 3 ft 50 lb 80 lb 50 lb 30 30 5 4 3 80 lb 3 ft d x 5 4 3 Probs. 479/80/81
