Part II

Using the beams and gears from your LEGO Crazy Action Contraptions book, construct a gear train assembly that results in a 45:1 gear ratio. That is, the output shaft should rotate only once for every 45 rotations of the input shaft. Bring your completed gear train to the team meeting on Thursday.

Hint: You will need some intermediate shafts. Hint: THINK! And apply what you know… the answer is not directly in your book… Problem solving means that you apply your knowledge to new situations.

List the gears on each axle below:
