illustrates how the forces can vary in problems of this type. A hiker, who weighs 739 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3250 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 of the force that a concrete support exerts on the bridge (a) at the near end and (b) at the far end?
