Question
The image shows a 550-kg uniform beam subjected to three external loads. The task is to compute the reactions at the support point O. The x-y plane is vertical, with positive values oriented to the right, upwards, and counterclockwise.

**Diagram Explanation:**

- **Beam:** The beam is horizontal, supported at point O, and extends to point C.
- **Support Point (O):** Located at the left end of the beam.
- **Loads:**
  - At point A (1.2 meters from O), there is an upward force of 2.9 kN.
  - At point B (2.9 meters from O), a counterclockwise moment of 27 kN·m is applied.
  - At point C (4.6 meters from O), a downward force of 3.6 kN is applied at a 30° angle to the vertical.
- **Distances:**
  - Distance OA = 1.2 meters
  - Distance AB = 1.7 meters
  - Distance BC = 1.7 meters

The goal is to determine the support reactions at point O, taking into account the given forces, moments, and distances.
