### Structural Analysis: Truss Load Evaluation

#### Problem Statement

**6.42** A floor truss is loaded as shown. Determine the force in members \( CF \), \( EF \), and \( EG \).

#### Diagram and Description

The diagram depicts a truss structure subjected to several vertical loads at multiple points. The truss layout is as follows:

- **Supports:**
  - Support at point \( A \) is depicted as a pin support.
  - Support at point \( K \) is depicted as a roller support.

- **Load Distribution:**
  - Point \( B \) has a downward load of 250 lb.
  - Point \( D \) has a downward load of 500 lb.
  - Point \( E \) has a downward load of 500 lb.
  - Point \( G \) has a downward load of 375 lb.
  - Point \( H \) has a downward load of 250 lb.
  - Point \( L \) has a downward load of 125 lb.

- **Spacing:**
  - Between each load application point (B, D, E, G, H, J) and their adjacent nodes, the horizontal distance is consistently 4 feet.
  - The distance from point \( I \) to point \( K \) is 2 feet.

The truss's nodes and the arrangement are denoted by alphabetic labels from \( A \) to \( L \). This framework must be analyzed to find the force within specific members noted as \( CF \), \( EF \), and \( EG \).

#### Figure Reference

- **Fig. P6.42 and P6.43**

The task is to analyze the structure and resolve the forces in the specific truss members mentioned above using static equilibrium equations.
