In England in the Middle Ages an extensive system of canals was used for transportation. Some of these canals crossed over canyons by flowing over bridges (viaducts). Suppose that a heavily loaded barge crossed over such a waterway bridge. A) The force on the barge would become less because some water would be squeezed off of the bridge. B) The force downward on the bridge would increase because of the added weight of the barge. C) The force on the bridge would not change when the barge passed over. D) The force on the bridge would become less because of the buoyancy effect of the water on the barge. E) Whether or not the force on the bridge would increase or decrease would depend on whether the water was flowing or stationary.
