Transcribed Image Text:**Problem 6**
**4-5.** The beam \( AB \) will fail if the maximum internal moment at \( D \) reaches \( 800 \, \text{N} \cdot \text{m} \) or the normal force in member \( BC \) becomes \( 1500 \, \text{N} \). Determine the largest load \( w \) it can support.
**Diagram Explanation:**
The diagram shows a structural system consisting of a beam \( AB \), which is horizontal and 8 meters long from point \( A \) to point \( B \). At point \( B \), there is a joint connecting to a slanted member \( BC \) that extends diagonally downward and to the right over a horizontal distance of 4 meters and a vertical distance of 3 meters, ending at point \( C \). The beam \( AB \) is supported at point \( A \) and subjected to distributed loads represented by downward arrows labeled \( w \).
The distance from point \( A \) to point \( D \) is 4 meters. The points \( A \), \( B \), and \( C \) indicate support or connection locations, with \( A \) and \( C \) being grounded supports.
Your task is to determine the maximum uniformly distributed load \( w \) that the system can sustain without exceeding the given failure conditions:
- Internal moment at point \( D \): \( 800 \, \text{N} \cdot \text{m} \)
- Normal force in member \( BC \): \( 1500 \, \text{N} \)
