Question

Find all moments in every joint from each member (in lb-ft).

The image features two diagrams on a grid paper, illustrating a beam structure with applied loads and dimensions. Below is a detailed explanation suitable for an educational website:

---

### Diagram Explanation

#### Diagram 1: Front View of the Beam Structure 

- **Points and Labels:**
  - The structure includes labeled points: A, B, C, D, and E.
  - Arrows indicate forces and moments along specific points.

- **Dimensions:**
  - The horizontal dimensions are labeled with an interval of 5 feet between A to B and B to E.
  - Vertical distances are indicated as 1 foot and 2 feet from A to B and B to C, respectively.

- **Load Applications:**
  - A constant distributed load of 200 pounds per foot (lb/ft) acts vertically downward from point B to point C.
  - A concentrated load of 800 pounds acts downward at point E.

#### Diagram 2: Sign Convention and Loading Directions

- **Sign Convention:**
  - Illustrations show the positive sign convention for moments and forces, with curved arrows.

- **Loading Directions:**
  - The loading directions on this smaller scale diagram use curved arrows at each joint (A, B, C, D, E) to depict the direction of forces and moments in the structure.

#### Additional Notes:
- The diagrams are drawn over a grid to maintain scale and precision, with each square likely representing one square foot.
- The notation `Positive Sign Convention` indicates the standard method for defining directions of forces and moments within beam calculations.

### Applications

These diagrams could be used for explaining basic concepts in structural analysis, including how to interpret loading conditions, analyze beam reactions, and calculate internal forces and moments.
