The reaction at the roller-supported end of a beam is always vertical.
Solución
To determine the nature of the reaction at the roller-supported end of a beam, we need to understand the characteristics of roller supports in structural engineering.
1. **Roller Support Characteristics**:
- A roller support allows rotation of the beam but does not allow translation in the vertical direction.
- It can provide a vertical reaction force to support the beam but does not provide any horizontal reaction force.
2. **Conclusion**:
- Since roller supports can only resist vertical forces and allow horizontal movement, the reaction at the roller-supported end of a beam is always vertical.
Therefore, the correct answer is:
**A). Vertical**

The reaction at the roller supported end of a beam is typically vertical. This is due to the fact that the roller allows for horizontal movement while restraining vertical movement, meaning it can support loads mainly in the upward direction. However, in certain configurations or external loading scenarios, there may be a component of horizontal reaction, but generally, the primary reaction force is vertical. This characteristic of roller supports is essential in structural engineering for maintaining equilibrium in beams.
