Handle diameter 0.625 in

### Overview

This diagram illustrates the mechanics of using a lug wrench to remove or tighten lug nuts on a tire. It provides a clear depiction of the leverage involved and the forces applied.

### Diagram Explanation

1. **Upper Portion:**
   - **Axle:** The horizontal section at the top represents the axle on which the tire is mounted.
   - **Lug Wrench (AB):** A tool used to apply torque to lug nuts, shown in an "L" shape with points marked A and B.
   - The vertical arrow labeled "3 in" indicates the length or distance from point A to the axle, representing leverage.

2. **Forces and Mechanics:**
   - **Point A:** The pivot or fulcrum where the wrench is attached to the lug nut.
   - **Point B:** The end of the wrench where force is applied.
   - The downward arrow labeled "F" shows the force applied at the end of the wrench to create torque.

3. **Lower Portion:**
   - **Tire:** A frontal view of the wheel shows the lug nuts arranged in a circle.
   - **Arrow from Point A:** Another arrow originating from A indicates the direction of the force applied when using the wrench.
   - The red arrow labeled "F" also shows the rotational force applied to loosen or tighten the lug nut, further emphasizing the torque concept.

### Educational Focus

- **Leverage and Torque:** This diagram is an educational representation of how torque is used in practical applications. It shows how applying force at a certain distance from a pivot point increases the rotational effect, making it easier to turn the lug nut.
- **Practical Mechanics:** Understanding how to properly use a lug wrench is essential for tasks like changing a tire, where the principles of physics are applied for efficient and effective manual labor.
