**Problem # 2 (8 points):**

A weight \( W = 300 \, \text{lb} \) is suspended by a cable system as shown in the figure.

a. Calculate the moment of force \( W \) with respect to point D (that means with respect to an axis normal to the paper that goes through D).

b. Determine all cable forces and the force in post BE.

**Hint:** Draw two different Free Body Diagrams (FBD’s) for points B and C, and solve separately.

**Bonus (1 point):** What is the magnitude of the resultant of tensions in cables BC and CD? Can you figure this out without any calculation?

---

**Diagram Explanation:**

The figure illustrates a cable system where a weight \( W = 300 \, \text{lb} \) is suspended. The system is anchored at points A, B, C, D, and E with the following setup:

- The horizontal distance from A to D is divided into three segments, each 8 feet long.
- A vertical post BE is 9 feet high.
- The vertical distance from B to C is 6 feet.
- The points form a triangular shape with AB and BE outlined.

The objective is to analyze this structure to find the moment, cable forces, and resultant tensions.
