A hiker, who weighs 990 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3550 N, and rests on two concrete supports, one at each end. He stops onefifth of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge at the near end?
