Now that you've finished the build, test what it does. Explore your build and then answer this question in your engineering notebook.
How would the speed of the arm change if the High Strength 84 Tooth Gear in the build's Step 33 was changed to a smaller diameter High Strength 60 Tooth Gear?
For help with this question, compare the rotational speed (RPM) of the High Strength 12 Tooth Pinion (from Step 36 of the build) to the rotational speed of the 84 Tooth Gear on the robot by gently moving the arm up and down. Be sure to justify your answer with your observation.
