C C Concept Simulation 9.1 illustrates how the forces can vary in problems of this type. A hiker, who weighs 871 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3510 N, and rests on two concrete supports, one on each end. He stops 1/3 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? C (a) Number i Units (b) Number i Units
