Draw the shear and moment diagrams for
the beam.

### Educational Explanation: Beam Diagram Analysis

This image presents a diagram of a beam subjected to various forces and moments, often used in structural engineering and mechanics.

#### Description of the Diagram

- **Beam Setup:**
  - The beam is horizontally oriented and anchored to a wall at point \(A\).
  - The length of the beam is divided into two equal segments:
    - **\(AB\)** is 5 feet.
    - **\(BC\)** is 5 feet.
  - The total length of the beam is 10 feet.

- **Forces and Moments:**
  - At point \(C\), at the end of the beam, there is a downward force of **100 pounds (lb)** applied vertically.
  - At point \(B\), there is a moment applied to the beam, depicted by a curved arrow, indicating a clockwise direction with a magnitude of **800 pound-feet (lb-ft)**.

#### Explanation

- **Support at Point \(A\):**
  - Point \(A\) is likely a fixed support or a wall, as depicted by the illustration indicating a rigid connection.
  
- **Point \(C\):**
  - The force at \(C\) represents a load applied at the end of the beam.
  - This load can cause bending and shear stress along the beam, influencing how the beam deforms under the applied weight.

- **Point \(B\):**
  - The moment at \(B\) indicates a rotational force applied to the beam.
  - Moments are typically caused by forces acting at a distance; in this case, it attempts to rotate the beam in a clockwise direction.
  - The magnitude of 800 lb-ft signifies the intensity of the moment.

The diagram provides essential information for calculating reactions at the supports and for analyzing the internal forces within the beam, such as shear forces and bending moments. Understanding these components is crucial for ensuring the structural integrity and safety of engineering designs.
