Draw the shear diagram for the beam. Click on "add vertical line off" to add discontinuity lines. Then click on "add segment" button to add functions between the lines. Note 1 - Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place two vertical lines at the same place, it will appear correct visually because the lines overlap, but the system will mark it wrong. Note 2 - Indicate the segments for all values of x shown in the diagram. Even if a segment is a constant value 0, it should be drawn in the diagram. + 0 No elements selected V, lb 600 500 400 300 200 100 0 -100 -200- -300- -400 -500 -600 50 lb/ft 20 ft m B 200 lb-ft 10 ft x, ft Press TAB to navigate between elements on the canvas.

### Instructions for Creating a Shear Diagram

To construct the shear diagram for a beam, follow these steps:

1. **Add Discontinuity Lines**: Use the "add vertical line off" option to introduce lines where there are discontinuities.
2. **Add Segments**: Click on "add segment" to define functions between these lines.

#### Important Notes:
- **Single Vertical Line**: Ensure that only one vertical line is placed at required points. Placing two lines at the same position may seem correct visually but will be marked as incorrect by the system.
- **Segment Value Indication**: Draw segments for all values of \(x\) shown in the diagram. This includes segments where the value is constantly zero.

### Diagrams Description

#### Beam and Load Diagram:
- **Beam Configuration**: 
  - A simply supported beam with:
    - A \(50 \, \text{lb/ft}\) uniformly distributed load over a 20 ft span from support A.
    - A point moment \(200 \, \text{lb-ft}\) acting at a 30 ft span from support B.
- **Support Reactions**: The beam is supported at points A and C.

#### Shear Force Diagram:
- **Vertical Axis (V, lb)**: Represents the shear force in pounds.
- **Horizontal Axis (x, ft)**: Represents the distance along the beam in feet.
- The graph illustrates the variation of shear force along the length of the beam, showing critical points and transitions.

### Navigation Instructions:
- **Tab Navigation**: Use the `TAB` key to move between elements on the canvas.
- **Menu Access**: Press `ALT+M` for the main menu.
- **Attributes Modification**: Press `ALT+A` to change attributes.
- **Quit Application**: Press `ALT+Q` to exit.

This setup helps in analyzing and determining the shear forces experienced within the beam structure under the given loading conditions.
