Transcribed Image Text:**Problem 4-116**
*Objective*: Replace the three forces acting on the shaft by a single resultant force. Specify where the force acts, measured from end \( B \).
---
**Diagram Explanation**:
The diagram presents a straight horizontal shaft supported at both ends, labeled \( A \) and \( B \). Three forces are acting on the shaft:
1. **500 lb Force**: This force is applied at an angle to the left of \( A \). The vector components indicate a horizontal force of magnitude 5 and a vertical force of magnitude 3.
2. **200 lb Force**: This force is applied vertically downward at a point located 3 feet from the first force and 5 feet from point \( A \).
3. **260 lb Force**: This force is applied vertically downward at a point located 2 feet from the 200 lb force and 4 feet from point \( B \). The direction of components is shown with a horizontal distance of 5 and a vertical distance of 12.
**Distance Measurements**:
- Distance between \( A \) and the first force: 5 ft
- Distance from the first to the second force: 3 ft
- Distance from the second to the third force: 2 ft
- Distance from the third force to \( B \): 4 ft
The objective is to determine a single resultant force that has the same effect as these three forces, and specify its point of application with respect to end \( B \).
