Illustrates how the forces can vary in problemsof this type. A hiker, who weighs 857 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform,weighs 4420 N, and rests on two concrete supports, one on each end. He stops 1/5 of the way along the bridge. What is the magnitude ofthe force that a concrete support exerts on the bridge(a) at the near end and (b) atthe far end?
