Its Now 150 Years That Scientists Can Not Prove Why A Bicycle Is Stable

Stakobrown 06/26/2020

There are some common machines we use in our homes, and places of work to ease of our daily affairs but we don't really know how it was invented, even they inventors don't know the true source of what is making what they invented to work. 


Scientists after making some inventions, they go back to analyze what is making it to work, in this process other news things are being discovered. The challenge scientists are facing now is to know the cause of a bicycle moving straight. Can you answer this?. Sounds funny right, but no scientist have come up with a good claim yet. 


The bicycle as we know it evolved in the 19th century thanks to the work of several different inventors. A German baron named Karl von Drais made the first major development when he created a steerable, two-wheeled contraption in 1817. This clunky wooden prototype didn't include a chain, brakes or pedals.


Scientist thought they knew the maths behind cycling. Michael Brooks said they were wrong and there efforts to figure it out are leading to some weird and wonderful new bike designs.

IN 2011, an international team of bi-pedal enthusiasts dropped the bombshell that, despite 150 years of analysis, no one knows how a bicycle stays upright. Across the world, riders dismounted and stared at their bikes in disbelief. What they had been doing for years cant be explained by science.


According to the researchers, it is a sort of, What they don’t know are the simple, necessary or sufficient conditions for a bicycle to be self-stable, says Andy Ruina, an engineer at Cornell University in Ithaca, New York.


We have relied on trial-and-error engineering to construct stable bikes that aren’t prone to toppling while in motion. Explaining how they work mathematically requires around 25 variables, such as the angle of the front forks relative to the road, weight distribution and wheel size.


Before 2011, researchers had reduced this profusion to two things. One was the size of the “trail”, the distance between where the front wheel touches the road and where a straight line through the forks would meet the ground. The other was the gyroscopic restoring force that acts on a spinning wheel to keep it upright.

Just like black which is yet to be understood by scientist. Its funny how a bicycle too is taking science 150 years to understand.

Picture of a black hole.

A black hole is a region of spacetime where gravity is so strong that nothin, no particles or even electromagnetic radiation such as ligh, can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.


Now if u are smart enough, drop your answers to how a bicycle remains up right. 


Rack your brain a little, don't forget follow.
