**Title: Analyzing a Pratt Roof Truss**

**Introduction**

This exercise focuses on analyzing the forces in a Pratt roof truss. The goal is to determine the force in each member of the truss and identify whether each member is in tension (T) or compression (C).

**Problem Statement**

- A Pratt roof truss is illustrated with the following given forces:
  - Load at point A: 5.7 kN
  - Load at point D: 10.5 kN
  - Load at point F: 10.5 kN
  - Load at point H: 5.7 kN

- A centralized load, P = 9.6 kN, is applied at point D.
  
**Truss Configuration**

- The truss is symmetrically arranged with:
  - Horizontal spans: AC = 3.8 m, CE = 3.2 m, EG = 3.2 m, GH = 3.8 m
  - Vertical height at point F: 2.4 m

**Objective**

Determine the force in each member of the Pratt roof truss and state whether each member is under tension (T) or compression (C).

**Instructions**

1. **Solve for the Reaction Forces:** Start with equilibrium equations to solve for reaction forces at supports (points A and H).
  
2. **Determine Member Forces:** Using static equilibrium for joints or sections, calculate force in each member.
   
3. **Identify Tension or Compression:** After computing the forces, deduce if each member is in tension (pulling, elongating the member) or compression (pushing, shortening the member).

**Note**

This step-by-step analysis is crucial for engineering design and ensures structural integrity and safety in real-life applications. Ensure all calculations are double-checked for accuracy.
