Measuring
September 16, 2005
The large gear in the Motorized Simple Machines sets have 40 teeth and the smallest have 8.
We made a gear train like the one for the turnstile and added a wheel
to use it to measure.
One time around is less than a foot. Five times is more than 4 feet.
25 time around is more than 20 feet.
