How many times will the medium gear rotate when the large gear makes one rotation? Round your answer to the nearest hundredth (like 3.47)

1

How many times will the large gear rotate when the medium gear makes one rotation?

1

Connect a large gear and a small gear. How many times will the small gear rotate when the large gear makes one rotation?

1

How many times will the large gear rotate when the small gear makes one rotation?

1

Now use all three gears: small, medium, and large.
Place the small gear between the large gear and the medium gear.
How many times will the medium gear rotate when the large gear makes one rotation? Round your answer to the nearest hundredth (like 3.47)

1

Place the large gear between the medium gear and the small gear.
How many times will the small gear rotate if the medium gear makes five rotations?

1

Place the medium gear between the large gear and the small gear.
How many times will the large gear rotate if the small gear makes eight rotations?

1

Write instructions for another person who doesn’t have gears in their hands to help them understand how to figure out how many times the smaller gear rotates for every one rotation of the larger gear. Be sure to reference the number of teeth in your explanation.

If a front gear had 24 teeth, and a rear gear has 12 teeth:
Each time the pedal goes around once, how many times does the rear gear (and wheel) go around?

1

If the pedal goes around 4 times, how many times will the rear wheel go around?

If the chain is on the 24 tooth front gear, and on the 8-tooth rear gear:
What is the gear ratio?

1

Will this combination result in a higher speed than the 2:1 gear ratio? Justify your answer.
