### Drawing the Free Body Diagram for a Uniform Beam

When analyzing structures, it's essential to break down complex forces and moments into simpler, manageable components. This process often involves creating a Free Body Diagram (FBD). Below, we will illustrate and describe the necessary steps to draw the Free Body Diagram for the given beam structure.

#### Diagram Description:

The structure illustrated is a simply supported beam with two supports labeled \( A \) and \( B \). The beam is uniformly loaded with three point loads. Here are the dimensions and forces described in detail:

**Beam and Support Layout:**

- The total length of the beam (\( L \)) is 20 feet (\( L = 20' \, 0" \)).
- Support \( A \) is a pin support located at the left end of the beam.
- Support \( B \) is a roller support placed at the right end of the beam.

**Applied Loads:**
 
1. **First Load:**
   - Magnitude: \( 5 \, \text{kips} \)
   - Position: 3 feet from support \( A \) (\( 3' \, 0" \)).

2. **Second Load:**
    - Magnitude: \( 14 \, \text{kips} \)
    - Position: 10 feet from support \( A \) (\( 3' \, 0" + 7' \, 0" = 10' \, 0" \)).

3. **Third Load:**
    - Magnitude: \( 6 \, \text{kips} \)
    - Position: 16 feet from support \( A \) (\( 3' \, 0" + 7' \, 0" + 6' \, 0" = 16' \, 0" \)).

Let's break down the distances for clarity:
   
- The first load is placed 3 feet from the left end at \( A \).
- From the first load, there is a 7-foot gap before the second load.
- The second load is placed 6 feet from the initial 3 + 7 = 10 feet mark.
- Finally, the third load is positioned 4 feet from the second load, indicating it is 20 feet from the left support \( A \).

### Points to Consider:

- **Supports:** 
  - **Pin Support (\
