Question
The diagram shows a structural system involving a beam supported at various points. The details are as follows:

1. **Beam ACDE**:
   - Member AC is inclined from point A to C.
   - A pin at point C fits into a smooth slot cut into member AC with no friction.

2. **Forces and Moments**:
   - A downward force of 300 lb is applied at point B.
   - There is a moment of 650 lb-ft applied at point A.

3. **Dimensions**:
   - Distance from A to C is 3 ft.
   - Distance from B to C is 4 ft.
   - Distance from C to D is 2 ft.
   - Distance from D to E is 2 ft.

4. **Supports**:
   - Point A and E have supports.

5. **Notation**:
   - X-axis is considered positive to the right.
   - Y-axis is considered positive upwards.

**Note**: The diagram is not to scale.

**Explanation**: The understanding of this system is crucial for analyzing the forces and stability of the structural element under the given loads and support conditions.
