Revolutionary Nano Gears: The Potential of Megaten Speed Bicycles

In summary, the conversation discusses the possibility of constructing gears smaller than those in modern ten speed bicycles, known as nano gears, and their potential use in a megaten speed bicycle. It is suggested that the first gear would be the same as a modern ten speed in order to get the bike moving, and the last gear's radius would be significantly smaller. The conversation also mentions the potential limits and challenges in creating such a bike, such as friction heat and structural integrity. The conversation ends by mentioning the availability of nano gears in Swiss watches and their current lack of commercial use.

Suppose that it was possible to construct gears smaller than ones of modern ten speed bicycles(nano gears) and suppose your chain or belt could turn them and withstand the friction. First gear of course would be the same as a modern ten speed in order to get it moving. If the last gear's radius was 10,000 times smaller than the first gear how fast could this megaten speed bicycle travel

How big are the wheels, how much force can the person push down on the pedals?

You can find it if you know the angular acceleration at the pedals.

It's certainly already possible to make gears way smaller than those in a bicycle; try dissecting a Swiss watch sometime. (And they have made nano-gears, but there's no immediate commercial use for them.)
The only theoretical limits that I can think of when it comes to a gear train show up when either the friction heat or the inertia overcome the structural integrity of the gears and cause them to fail.
As for the practical limits, Cyrus has it covered.

1. What is Leonardo's gear sketch?

Leonardo's gear sketch is a drawing made by Leonardo da Vinci, a renowned Italian artist and inventor, that depicts a complex arrangement of gears.

2. When was the gear sketch created?

The gear sketch was created in the late 15th or early 16th century, during Leonardo's time in Florence, Italy.

3. What was the purpose of the gear sketch?

The purpose of the gear sketch is not entirely clear, but it is believed that Leonardo intended to use it as a model for creating a perpetual motion machine or other mechanical device.

4. Is the gear sketch considered a work of art or a scientific document?

The gear sketch is considered both a work of art and a scientific document, as it showcases Leonardo's mastery of both fields and his ability to combine them in his work.

5. How does the gear sketch demonstrate Leonardo's genius?

The gear sketch demonstrates Leonardo's genius by showcasing his innovative thinking and detailed understanding of mechanical principles, as well as his ability to merge art and science in a single work.
