### Diagram Explanation

The diagram shows a structural beam subjected to multiple forces and moments in a three-dimensional coordinate system with axes labeled as x, y, and z.

- **Forces:**
- A 40 N force acting vertically upward at a distance of 2 m along the beam.
- A 30 N force acting vertically downward, also 2 m along the beam.
- A 70 N force acting downward at an angle, 3 m along the beam in the x-direction.
- A 50 N force acting horizontally towards the negative x-direction over a span of 3 m from the origin.

- **Moment:**
- A couple of 300 N·m acting around the beam, directed along a slightly angled axis.
