Current Attempt in Progress
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 = 61 lb, F2 = 74 lb, F3 = 43 lb, F4 = 57 Ib, a = 73 in., b = 61 in., and 0 = 44°.
