Four signs are mounted on a frame spanning a highway, and the magnitudes of horizontal wind forces acting on the signs are given as: A = 205 lb, B = 240 lb, C= 280 lb, D = 350 lb. Determine the magnitude and the point of application of the resultant of the four wind forces when a = 1 ft and b = 12 ft. EB D C 8ft 5 ft A 9 ft 5.5 ft 3.ft 2.5 ft The resultant of the four forces is 1075 lb. The point of application of the resultant force is 14.830 ft to the right of member AB and 3.116 ft above member BC Four signs are mounted on a frame spanning a highway, and the magnitudes of horizontal wind forces acting on the signs are given as: A = 205 lb, B = 240 lb, C= 280 lb, D = 350 lb.
