A hiker, who weighs 919 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3630 N, and rests on two concrete supports, one at each end. He stops one-fifth 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?
