Transcribed Image Text:**Problem 4:**
A beam is supported at two points, A and B. The total length of the beam is divided into three segments. From point A to the first segment, the length is 2.75 meters. The next segment is 6.5 meters, and the final segment is also 6.5 meters leading to point B.
**Loads on the Beam:**
1. **Point Load:** 115 kN acting downward at the junction between the first and second segments.
2. **Distributed Load:** A rectangle with a uniform distributed load of 50 kN/m over the 6.5-meter second segment.
3. **Triangular Distributed Load:** Over the last 6.5-meter segment, increasing linearly from zero at the junction with the second segment to 150 kN/m at point B.
**Supports:**
- Support A is a pin support.
- Support B is a roller support.
**Objective:**
- Calculate the reactions at supports A (RA) and B (RB).
This setup demonstrates a typical analysis problem in structural engineering courses, where understanding the distribution of forces and how they are counteracted by supports is crucial for ensuring stability.
