Question
**Beam Analysis Problem**

Objective: Sketch the internal shear and moment as a function of the beam length.

**Description:**
- The beam is supported at two points: A and B.
- Point A has a triangular symbol indicating a pin support, which allows rotation but no translational movement.
- Point B has a circular symbol indicating a roller support, which allows horizontal translation but no vertical movement.
- The beam is subjected to a central downward load \( P \).

**Key Parameters:**
- Total length of the beam is \( L \).
- Distances \( a \) and \( b \) from the supports to the load are equal: \( a = b = L/2 \).

**Support Reactions:**
- \( R_A \) and \( R_B \) represent the vertical reaction forces at supports A and B, respectively.

The task is to represent how the internal shear force and bending moment vary along the length of the beam due to the applied load \( P \).
