Please help with question attached. 

The girder shown is supported by columns A and B. Two smaller beams push downward on the girder with a force of 40 kN at C, and two other beams push downward with a force of 50 kN at D. Find the reactions at A and B.

### Explanation of Diagram

- **Steel Girder**: The horizontal member supported by columns A and B.
- **Steel Columns A and B**: Vertical supports at each end of the girder.
- **Steel Beams at C and D**: Smaller beams exerting forces on the girder. 
- **Forces**:
  - 40 kN downward force applied at point C.
  - 50 kN downward force applied at point D.

The diagram shows the spatial arrangement of these elements with equal distances of 2.5 meters between points A, C, D, and B. The task is to calculate the support reactions at columns A and B due to the external forces applied at points C and D.
