Question #2: Suppose you needed to replace the 2000 lb force in the figure below with a horizontally- oriented force through point A, a vertically-oriented force through point C, and a couple. Give the vector expressions for the forces through A and C as well as the vector expression for the couple. Your vector expressions will depend on your choice of coordinate system (which direction relative to the figure you choose for x, y, and z) so please be sure to show your coordinate system on your schematic and free-body diagrams. 2000 lb 30° B 5 ft A 2 ft

Question
**Question #2:** Suppose you needed to replace the 2000 lb force in the figure below with a horizontally-oriented force through point A, a vertically-oriented force through point C, and a couple. Give the vector expressions for the forces through A and C as well as the vector expression for the couple. Your vector expressions will depend on your choice of coordinate system (which direction relative to the figure you choose for x, y, and z) so please be sure to show your coordinate system on your schematic and free-body diagrams.

*Diagram Description:*
The diagram features a rectangular block standing upright. Key points and measurements are:

- A 2000 lb force is applied diagonally from the top-left corner (point B), forming a 30-degree angle with the horizontal axis.
- The block has a height of 5 feet and a width of 2 feet.
- Point A is at the bottom-left corner and point C is at the bottom-right corner of the block.
- The force vector is represented with an arrow extending from point B angled downward to the right, indicating the direction of the force on the block.
