I computed the length off all 15 pendulums following the (correc)t formulae given in the animation and explanation. The results have been checked by a professional mathematician. The next lengths are given in cm's for pendulum nr 1 (the longest) up to and including pendulum nr 15 (the shortest) : 34.4 33.1 31.8 30.7 29.6 28.5 27.6 26.6 25.7 24.9 24.1 23.3 22.6 21.9 and 21.2 I applied these lenghts and it really works !!!!!!
Have any of you noticed the number of rows of pendulums that appears through the cycle? At 30 seconds there are two rows of pendulums (30 is half of 60), and at 15 and 45 seconds, there are 4 rows (15 is a quarter of 60 while 45 is three quarters of 60), and at 20 and 40 seconds, there are 3 rows (20 is one third of 60 while 40 is 2 thirds). It seems that the number of rows formed by these pendulums through the cycle correspond to the numbers dividing into 60: At 30 seconds- 2 rows formed by the pendulums. 60/30 equals 2, or 30 is 1/2 of 60; At 20 seconds- 3 rows. 60/20 equals 3, or 30 is 1/3 of 60; At 15 seconds- 4 rows. 60/15 equals 4, or 15 is 1/4 of 60.
If you divide the length of the cycle (60 seconds) by 2 (30 seconds), then you should see 2 rows at the 30 second mark. Likewise, If you divide by 3 then you should see 3 rows at 20 seconds and 40 seconds. And so forth...
Unfortunately is the computed length of the 15th pendulum being 218,6 mm is incorrect. That is the lenght of the 14th pendulum ! Thec orrect length of the 15th pendulum is, following the presented formulae 211,9 mm
This is really cool. Can you eliminate friction from your model? I'm interested to see how the balls move in and out of sets of balls that look like a solid rod. I think that phenomenon might be more apparent if you used 24 (or 23?) balls since 24 is divisible by 2, 3, 4, 6, 8 and 12.
Excellent video. But there is a mistake in the result. Namely, the length of the 15th pendulum should be 211.7 mm instead of 218.62 mm. It is just calculation mistake.
I found the same mistake and am wondering the same thing. The 218,62mm length corresponds to the 14th sphere according to my calculations. For the 15th one I have 211.66mm (using g=9.80665)
I am not a physicist and I have no idea what is happening, but I still like that video... Good work.
This video will be very useful for my physics project. Thanks a lot for sharing it. Amazing work.
Hi
I need your help

Does the mass of steel bearings matter?

The most perfect one I've seen.
That's really freakin cool.

Ty for the information for my project❤
I found it like DNA and RNA,s structure..... ❤️
Transversal waves the back and forth motion a good model for physics one .

Wow
Incredible work!
Does it ever stops
Assuming no resistance so no.
Itinéraire stops After 60 sec
Thank you so much, this video was so useful in making my Giant Portable Pendulum Wave! @
Can you tell me the diameter of the sphere? tks
Diameter doesn't matter, as long as the lengths stay constant
Amazing
what is the song called?

Great😊
Interesting
Parece música de parque temático fuleiro.
como se lama la cansion
it's great
It's amazing until you realize all the strings are different lengths.
love it :)
who tf cares bro
