Question
The diagram depicts a 3D setup involving a member AB, which is supported by a cable BC. The system is subjected to external forces: a 400 N force acting vertically downward and a 200 N force acting horizontally along the negative x-axis. 

Key elements of the diagram:

- **Member AB**: Positioned vertically along the z-axis.
- **Point A**: The upper end of the member, fixed at 3 meters from point B, with a horizontal distance of 1.5 meters to point C.
- **Cable BC**: Extends from point B to point C, providing support and stability.
- **Forces**: 
  - A 400 N force is applied downward on member AB.
  - A 200 N force is applied horizontally towards the member.
- **Coordinates**:
  - Member AB spans from point B at (x = 0, y = 0, z = 0) to point A (z = 3 meters).
  - Point C is located at 1.5 meters along the y-axis from point A.

Summary of the Problem Statement:
"Member AB is supported by a cable BC and at A by a square rod, which fits loosely through the square hole in the collar fixed to the member as shown. Which of the following is closest to the force in cable BC?"

**Problem Statement:**

Member AB is supported by a cable BC and at A by a square rod which fits loosely through the square hole in the collar fixed to the member as shown.

**Objective:**

Which of the following is closest to the force in cable BC?

**Given Information:**

- A force of 200 N is applied horizontally at point B.
- Distance from the point where the rod meets the edge of the collar to the rod is 1 m.
- The unit vector along cable BC is \( \mathbf{u_{BC}} = \{-0.857i + 0.429j + 0.286k\} \).

**Diagram Explanation:**

- The diagram illustrates member AB with a horizontal force applied at point B.
- A cable (BC) supports the member, extending diagonally upwards and right from point B to point C.
- The horizontal force is labeled as 200 N, acting towards the left.
- The diagram includes vector directions and positional information relevant to calculating forces.
