**Problem #3 (7 points):**

The bent pipe resists forces as shown. Determine the moment of each force about each of the coordinate axes (9 results required).

**Diagram Explanation:**

A 3D coordinate system is shown with axes labeled X, Y, and Z. A bent pipe extends vertically along the Y-axis, named points A, B, C, and D.

- **Pipe Dimensions:**
  - AB = 40 inches (vertical segment along the Y-axis)
  - BC = 25 inches (horizontal segment along the X-axis)
  - CD = 12 inches (horizontal segment parallel to the X-Z plane)

- **Forces Applied:**
  - **F1** = 200 lbs, acting at point B, directed upwards and diagonally aligned with the positive Y-axis.
  - **F2** = 500 lbs, acting horizontally at point C, directed towards the right in the positive direction parallel to the X-axis.
  - **F3** = 400 lbs, acting vertically downwards at point A, aligned with the negative Y-axis. 

The goal is to calculate the moments created by each force about each coordinate axis (X, Y, Z), requiring a total of 9 calculations.
