### Problem Statement

**Question:**  
What is the maximum absolute shear for the following beam and load group?  

**Given Values:**
- \( L = 20 \)
- \( a = 3 \)
- \( b = 3 \)
- \( P_1 = 3 \)
- \( P_2 = 3 \)
- \( P_3 = 1 \)

### Diagram Explanation

The diagram depicts a beam that is fixed at the right end. The beam has a total length \( L \). There are three point loads acting on the beam: \( P_1 \), \( P_2 \), and \( P_3 \). These loads are applied downwards.

- **Beam Layout:**
  - The beam's left side is unsupported, and the right side is fixed.
  - The total length (\( L \)) is divided into sections marked by distances \( a \) and \( b \), starting from the left end where the loads are applied.

- **Load Placement:**
  - \( P_1 \) is applied at a distance \( a \) from the left end.
  - \( P_2 \) is applied at a distance \( b \) from \( P_1 \).
  - \( P_3 \) is applied further along the beam.

- **Point Loads:**
  - \( P_1 = 3 \)
  - \( P_2 = 3 \)
  - \( P_3 = 1 \)

This setup is used to determine the maximum absolute shear experienced by the beam.
