: Reactions, Shear Force, and Bending Moment

1. Calculate the upward forces at A and B ($R_A$ and $R_B$)

First, let's identify all loads and their positions. We'll set the origin ($x=0$) at the left end of the beam.

• Point Load 1: $5 \text{ kN}$ at $x=0 \text{ m}$.
• Support A: Pin support at $x=3 \text{ m}$.
• Point Load 2: $4 \text{ kN}$ at $x
