Four people are attempting to move a stage platform across the floor. If they exert the horizontal forces shown, determine (a) the equivalent force-couple system at O and (b) the points on the x- and y-axes through which the line of action of the single resultant force R passes. Assume F₁ = 87 lb, F₂ = 85 lb, F3 = 46 lb, F4 = 55 lb, a = 82 in., b = 64 in., and 0 = 44°. y F.
