Question
**Concept Simulation 9.1**

This simulation illustrates how forces can vary in problems of this type. A hiker, who weighs 935 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 4500 N, and rests on two concrete supports, one on each end. He stops 1/4 of the way along the bridge. 

**Problem Statement:**
What is the magnitude of the force that a concrete support exerts on the bridge at:
- (a) the near end
- (b) the far end

**Answers:**

(a) Force at the near end:  
- Number: 2483.75 N  
- Units: N (Newtons)

(b) Force at the far end:  
- Number: 2951.25 N  
- Units: N (Newtons) 

This simulation helps to understand the distribution of forces in static equilibrium conditions when additional weight is added to a structure.
