### Problem 3

#### Objective:
Draw the moment diagram for the beam using the **method of superposition**.

#### Beam Diagram:
The beam is simply supported at two points (A and B) and is subjected to the following loads:
- A uniformly distributed load of 10 kN/m over a span of 8 meters from point A to point B.
- A point moment of 80 kN·m applied at point B.
- A point load of 25 kN applied at point C, 4 meters from point B.

#### Diagram Explanation:
- **Support A**: Simply supported, located at one end of the beam.
- **Support B**: Simply supported, located 8 meters from support A.
- **Point C**: Located 4 meters from support B (or 12 meters from support A).

#### Detailed Components:
1. **Uniformly Distributed Load (UDL)**:
   - Magnitude: 10 kN/m.
   - Span: 8 m from support A to support B.

2. **Point Moment**:
   - Magnitude: 80 kN·m.
   - Applied at point B.

3. **Point Load**:
   - Magnitude: 25 kN.
   - Applied at point C (12 meters from support A and 4 meters from support B).

#### Dimensions:
- The total length of the beam is 12 meters.
- Segment AB: 8 meters.
- Segment BC: 4 meters.

### Visual Representation:
The beam diagram is illustrated with the following notation:
- **A horizontal beam** extends horizontally with supports and loads marked.
- **Downward arrows** indicate the uniformly distributed load (UDL).
- **Curved arrow** at point B shows the applied moment.
- **Vertical arrow** at point C denotes the point load.

Use this detailed information about the loads and supports to draw the moment diagram, applying the method of superposition to determine the moments along the beam.
