Question

The pipe assembly is subjected to three forces of F1 = {3.00, 4.00, -2.00} kip, F2 = {0, 0,-4.00} kip, and F3 = {-3.00, 0, 0} kip. Determine the sum of the moment of the forces

1) about x-axis (the unit vector of x is i) and

2) about line AC. Express the result as a Cartesian vector.

This image depicts a three-dimensional diagram of a rectangular structure on a grid background. The diagram includes the following elements:

- **Axes:**
  - The x, y, and z axes are labeled for orientation in a 3D space.
  - Arrows indicate positive directions on each axis.

- **Structure:**
  - The structure consists of a rectangular frame labeled with points A, B, C, and D.
  - Point O is at the origin, where axes intersect.
  
- **Dimensions:**
  - The length along the x-axis from point B to point C is labeled as 6 units.
  - The length along the y-axis from point C to point D is labeled as 1 unit.
  - The length along the z-axis from point B to point A is labeled as 4 units.
  - The height from point C to the base of the structure is noted as 2 units.

- **Forces:**
  - Force \( F_2 \) is shown directed downwards along the y-z plane from point B.
  - Force \( F_3 \) is depicted to the right along the positive y-axis from point D.
- **Notation:**
  - Points are labeled A, B, C, D, to mark significant parts of the structure.
  
This diagram may represent a mechanical or structural engineering concept, illustrating forces and dimensions within a 3D coordinate system.
