Given: A painter weighing Wman = 180 lb stands on a ladder. The uniform ladder has weight Wladder = 40 lb. The center of gravity (C.G.) of the painter is located at a = 2.5 ft and b = 6.0 ft. Let L = 6 ft and H = 12 ft.

Req'd: Determine the magnitude of the reaction force at B. Assume that Point A acts as a roller and Point B acts as a pinned support.

RB =  lb  (1%)
