### Shear and Bending Moment Diagrams

#### Objective:
Derive the shear force and bending moment diagram for the provided beam loading.

#### Beam Loading Description:
- The beam has a hinge support at point A and a roller support at point D.
- Point loads of 500 N are applied downward at points B and C.
- A uniformly distributed load of 2400 N/m is applied between points D and E.

#### Beam Specifications:
- Length between supports A and B: 0.4 m
- Length between supports B and C: 0.4 m
- Length between supports C and D: 0.4 m
- Length between supports D and E: 0.3 m

#### Steps:

##### a) Using the method of cutting the beam at several points at distance \( x \) from A:

1. **Calculate Reactions at Supports**:
    - Sum of vertical forces and moments to determine the reaction forces at supports A and D.

2. **Shear Force and Bending Moment Calculations**:
    - Divide the beam into segments (AB, BC, CD, DE).
    - Write equilibrium equations for each segment to determine the shear force (V) and bending moment (M) for the beam.

##### b) Using the relationship between V, w, and M:
   
Given the relationships:
\[ \frac{dV}{dx} = -w \]
\[ V = \frac{dM}{dx} \]

1. **Shear and Moment Distribution**:
    - Use the differential relationships to derive the expressions for shear force (V) and bending moment (M) along the beam.

#### Explanation of Graphs and Diagrams:

- The **Shear Force Diagram (V)** typically plots the shear force values along the length of the beam.
- The **Bending Moment Diagram (M)** plots the bending moment values along the length of the beam.
- Transitions and discontinuities in these diagrams occur at points of applied loads and supports.

**Note on Diagrams**:
- The diagrams should illustrate the changes in shear force and bending moment at each segment of the beam.
- The vertical loads will create downward spikes in the shear force diagram.
- Support reactions will cause upward spikes in the shear force diagram.
- In the bending moment diagram, moments are highest where shear changes sign (zero-crossings).

The objective is to comprehend the distribution of internal forces resulting from external loads and to use
