Lesson 3
The Wheel & 
Axle
Graphing
To look at the relationship between wheel radius and effort force, use the data from Table 2 to complete the graph in your lab packet.
- What happens to the effort force as the radius increases? Use complete sentences to record your answer in your lab packet.
- Do your results match your predictions?
- Record a comparison between your predictions and your results in your lab packet.
Let's take a closer look at this wheel and the attached screw (axle) to get a better understanding of what is happening.
We can think of the wheel and axle as a specialized lever.
