Problem 1. Determine the reactions present at the pin A and roller B required for equilibrium of the beam.

(Final Answers should be  FBD: Ay = 2230 N, Ax = 0, B = 2170 N

 

**Problem 1**: Determine the reactions present at pin A and roller B required for the equilibrium of the beam. 

(Final Answers – signs depend on FBD: Ay = 2230 N, Ax = 0, B = 2170 N)

---

### Diagram Explanation:

This is a simply supported beam with a length of 8 meters in total. It is supported by a pin at point A and a roller at point B. 

- **Pin at A**: Restrains movement in both horizontal and vertical directions.
- **Roller at B**: Restrains movement only in the vertical direction.

#### Load Distribution:

- There is a uniformly distributed load (UDL) that starts at 800 N/m at point A and linearly decreases to 400 N/m near the right end. This load is applied over a span of 6 meters.
- At the end, near point B, there is a horizontal segment of 2 meters without any load variation.

#### Reaction Forces:

- **Ay**: The vertical reaction at pin A, calculated to be 2230 N.
- **Ax**: The horizontal reaction at pin A, which is 0 N since no horizontal loads are applied.
- **B**: The vertical reaction at roller B, calculated to be 2170 N.

This setup ensures that the beam is in equilibrium under the given load conditions.
