🔍⚙️ How Accurate Is This Pi Demonstration?

355/113 is quite close

Finally… a proof of π I can eat 😄🍕

Auccuracy: .27 isn't ~.14

Yes dear 😄📏 It’s definitely not exact accuracy — just a fun mechanical approximation of π.

This is not accurate: The 3 bigger chains have 11 nods each, Thus the smaller part should have 11 x 0.14 = 1.54 nodes but the chain shown have 3 nodes.

Good point 😄 It’s more of an approximation than an exact proof.

this is probably a pretty good fit since the chain is made to fit on that sprocket to begin with. so now pi is (3*11+3)/11=3.27272727272727... near enough then

Nice observation 😄📏 For a mechanical approximation, that’s actually a pretty clever and close result to π.

Accurate enough, but not 100%. Nobody, I say NOBODY has recorded PI 100% accurately. And that is the difference between knowledge and wisdom. Knowledge, knowing Pi is irrational. Wisdom, knowing 3.14 is accurate enough in a lot of places.

I appreciate the way you see it.

Super cool way to show Pi in real life 🔥

@Riddhi1450 Exactly 👍🏻🔥

3/11 is .27 🤷‍♂️

Exactly 😄 So it’s just a rough approximation of π.

Small yellow part is not 0.14 of it. It is 0.2727 of it.

Если бы добавил к каждому длинному отрезку цепи по еще одному звену, то Пи было бы равно 3. Не благодарите.

Remember when Pi = 3? Those were good times.

Now I want pie 🥧

He shows 2 x r = 1 => r = 1/2 Circumfence C = 2 x pi x r and r=1/2 follows C = 2 x pi x 1/2 = pi. So, pretty accurate 🙃

...I spent the last hour tracking down and downloading that song! 😂

Enjoy it ☺️

The chains has 5.5 of this cogs or whatever they are called and the last one has 1.5. 5.5:1.5=1:x, 5.5x=1.5, x= 1.5/5.5, x=0.27 which is not 0.14. So by your example pi is 3.27

So 4

Why is everyone counting the pins rather than the plates? That’s like counting starting from 0. The math is 10+10+10+2. 3.2 is a good approximation for pi (2% off). The pitch circle of the sprocket is slightly larger than what he measures with the lengths of chain.

Perimeter of circle= 2Pi*r

If the chain had a possible zero width and a length from the edge to the edge of the gear, it would be correct. At this width, the chain marks two different lengths of circuits.

It's rational...

Pi is the proportion between diameter and circumference of a circle, no mater its size. That easy.

Pi there is 3.2 exactly

That’s actually pretty close 😄📏

What if I had a bigger sprocket ⚙️ that demands more chains ⛓️ ???

How can i understand this if there is not a phonk edit?

Pi? Isn't that just half of tau?

Off by 4.17%

huh...so that's what pi means. very cool...thank you!

pretty cool

Thanks 🙏🏻

This will get you a more accurate pi. It is required to put it into tables. There's also a really easy simplier one. 22/7 is inaccurate.

not very, but it's colourful and easy to understand and it very effectively explains what pi is so it's pretty cool, actually.

Name the song everyone

Pi is 3 actually — engineers

nice !!!

97% as 2.0 / 9.0 = 0.22 so ~ 3.22, divided by pi is 0.975
