### Understanding Torque and the Use of a Lug Wrench

This educational resource explains the concept of torque using a practical example of a lug wrench and a tire.

#### Diagram Breakdown:

1. **Top View:**
   - The diagram shows an axle with a lug wrench.
   - The distance from point A (where the wrench is applied) to point B (end of the wrench) is 3 inches. This distance is crucial as it represents the lever arm for calculating torque.

2. **Lug Wrench:**
   - It is an L-shaped tool used to apply force at one end to rotate the axle.
   - The position labeled "A" indicates where force is applied.

3. **Bottom View:**
   - The tire is attached to a central axle, which is part of the system being rotated.
   - The red arrow labeled "F" represents the force being applied downward at the end of the wrench to create torque.

#### Concepts:

- **Torque (τ):** It is the rotational equivalent of linear force. Torque is calculated as:
  \[
  \tau = r \times F
  \]
  where \( r \) is the lever arm (3 inches in this case) and \( F \) is the force applied perpendicular to the lever arm.

- **Lever Arm:** Distance from the axis of rotation (axle) to the point where force is applied (3 inches).

- **Force Application:** The effectiveness of the applied force depends on the angle and distance from the pivot point, showing how leverage increases force through distance.

This setup demonstrates how a lug wrench is used to create sufficient torque to loosen or tighten the lug nuts on a vehicle’s wheel, illustrating the practical application of leverage and rotational force.
