Question
**Problem 6:** Replace the force of \( F = 80 \, N \) acting on the pipe assembly by an equivalent resultant force and couple moment at point \( A \).

**Diagram Explanation:**

The diagram shows a 3D pipe assembly with a force \( F = 80 \, N \) applied at the lower end of the pipe. The structure forms an angled path, with the following key dimensions and angles:

- A fixed point \( A \) is positioned 400 mm along the z-axis.
- The pipe bends and extends to point \( B \), 300 mm along the y-axis.
- A further segment extends 200 mm parallel to the x-axis.
- Another section of 250 mm length forms a 40° angle with another direction.
- The force \( F = 80 \, N \) is applied at an angle of 30° to the horizontal in one segment.

The challenge is to determine the equivalent force and couple moment at point \( A \) that would have the same mechanical effect on the assembly as the original force applied.
