Three blocks with masses m1 = 4.08kg, m2 = 2.07kg, and m3 = 17.3kg are shown in the diagram. What must the value of |F| be to keep m1 and m2 stationary with respect to m3?

I would say that the force of m2 is mg=(2.07)(9.8), assuming no friction. Force of m1 is also mg = (4.08)(9.8). I am not sure what the magnitude of F would have to be for these masses to remain stationary.
