**Problem 6–33**

**Objective:** Determine the force in members \( BC \), \( HC \), and \( HG \) of the bridge truss and state if the members are in tension or compression.

**Diagram Explanation:**

The image depicts a truss bridge structure with the following details:

- **Support Points:** 
  - Point \( A \) is a pin support.
  - Point \( E \) is a roller support.

- **Span and Height:**
  - The horizontal span between points \( A \) and \( E \) is divided into three segments of 3 meters each.
  - The vertical height from the ground to the top of the truss at points \( H \) and \( F \) is 3 meters.

- **Forces Applied:**
  - A downward force of 12 kN is applied at point \( B \).
  - A downward force of 14 kN is applied at point \( C \).
  - A downward force of 18 kN is applied at point \( D \).

- **Truss Members:**
  - The truss consists of members forming triangles and rectangles within the structure, with joints labeled \( A, B, C, D, E, F, G, H \).

The goal is to calculate the forces in specific members and identify whether they are in tension (pulling apart) or compression (pushing together).
