**Problem Statement:**

6. The pipe assembly is subjected to an 80-N force. Determine the moment of this force about segment AB of the pipe. Determine the moment about point A, and the orientation of the axis of rotation.

**Diagram Explanation:**

The diagram illustrates a pipe assembly with several segments in space. The axes are labeled \(x\), \(y\), and \(z\). The pipe segments proceed through several directional changes:

- Segment \(AB\): Runs horizontally 400 mm in the positive \(y\)-direction.
- Segment \(BC\): Runs vertically downward 300 mm from point B, then turns 90 degrees.
- Segment from a point down: Extends downwards and to the left.

Key Measurements:
- Horizontal Segment (AB): 400 mm
- Vertical Segment (BC): 300 mm
- Downward Segment: Extends at an angle with 250 mm horizontal and 200 mm vertical measurements.
  
There are two angles shown:
- 40° from the horizontal plane.
- 30° below the unknown angled line.

The 80-N force \(F\) is applied downward at the angle indicated by the two angles presented. An arrow is used to show the direction of the force applied at point C.

**Objective:**

1. Calculate the moment of the 80-N force about segment AB of the pipe.
2. Calculate the moment about point A.
3. Determine the orientation of the axis of rotation.
