Wheel with a shifted center of gravity

[EliaForce1984ita]

lol, parlano in italiano nel video (they speak italian in the video)

[katlyn6090]

Inceptionnnnnnn

[misser902]

One two three four I declare a rig war!

[DamienPalianta]

@misser902 Fice six seven eight, i use this rig to procrastinate... >.>

[TheGreat747]

anyone from the useless machine?

[georgelol99]

wow that was.........shit

[borgcrickett]

22 seconds of my life wasted...

[Oshyrath]

I actually get the concept but you're video taping it wrong and gave it the wrong tittle.

[lp000028]

waist of research

[harutape]

i think wheel really has shifted center of gravity and it does not go through full rotation that is why it rolls back there is no magic there

[EnigmaKaze]

Yea, but will it blend?

[nicodanger13]

inquadratura sbagliata..

[catchersmitt0]

well that was a snooze

[Urstupidumbass]

Isnt this common sense...

[jaghatarkebab]

Correct me if I'm wrong. That yellow thingy has a center weightpoint. That point is struggling to get down as far as possible (as is everything that has a weight). Since the weightpoint is lower at the wide part of the track than at the thin part, even though it goes up, it goes up.

FRIKKIN MIRACLES

[Puzzicanello]

I'M ITALIAAAAAAAAAAAAAAAAAAAAAAAAA­AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA­AN!!!!

[V8block8]

this is obvious i think everybody has done it with two pool poles and some pool balls

[chengda85]

troll science!

[dontmessmagic]

INFINITE ENERGIES

[MrRhcpLover]

that guy says ninja at the end

[icovada]

@MrRhcpLover He said "si stringe" = it gets narrower

[Puzzicanello]

@MrRhcpLover No he doesn't xD

[ncpsubf]

The picture looked like one those toys but wow giant

[Rboysblaster]

lol the center of gravity shifts says the description, the description also says about the force created by this makes it go up the slope...

OH NOW I get it... now I see, if I walk 10 meters my center of gravity will have shifted about 10 meters so..... I discovered how to FLY! since the description seem to asssume that shifting the center of gravity creates a force pulling the object of which the center of gravity has shifted upwards? lol... just.. lol -.-

[MrGolbs]

i know whats wrong!

Gandalf is stood at the end of the poles shouting

"YOU SHALL NOT PASS!"

and the wheel is like

"Okay, sorry =("

[sethboy66]

WHAT SORCERY IS THIS!

[djbro16]

the worlds most worthless yo yo

[two45triox]

This was a toy years ago. Anyone remember it?

[NejiHyuga296]

@two45triox Yes! God I loved that thing! XD

[5jerry1]

@two45triox

"Wacky Wheel."

[prashantkarade]

@two45triox yup

[DKM101]

the change of the center of gravity is vertical. Since the force pushing the wheel up is less than the force pulling the wheel down, it decelerates, and accelerates back "up" the slope (but its center of gravity goes down).

[corotor12345]

@DKM101

No, it doesn't go back down. Or well, yes it does, but then it goes back up again. My point is that both the spot where they let go of it, and the place where it begins to run back "up", are both places where the center of grvity is at it's maximum height. With time, it'll come to a halt between those two points. It's galileo, he and newton set the standard for this kind of reasoning.

[DKM101]

@corotor12345

ya, its like dropping a ball down a half-pipe in 2d. Im bad at talking.

[cronon94]

"hell no, im not going down there"

[MrBodeci]

the item never rolls up it rolls level it appears to roll up but it droping down as it goes back

[KingLukey123]

mannnnn....i wish i new what u guys were talkin bout'.....i kinda doo.... but ur smarter than me anyways...lol

[greg5566]

This is called a Wheel-o. Look it up.

[DamodharanR16]

not free energy, but kinetic+potential energy ofcourse

[rosserver]

NO tiorojo you are wrong

Yes jagara, exactly...

...it's the large version of a toy they used to sell when I was a kid.

[RomanianUser]

o_O

[ANGELO13111]

gravity always amazed me.

[powdermonkey1111]

Or at least this is the case as far as can remember from high school Science classes. I may be wrong, but that was the impression I was under.

[cr1tterp0wer]

Grospoliner= awesome

[lc123666]

no sry

[motabikeboy]

HOLD ON!

is this a exmaple of peptual motion.

[Grospoliner]

No it is not. What happens is, with the c.o.g. shifted out of the center of mass (i.e. weighting down one side of the wheel) a moment arm is created which forces the wheel to spin the other way.

Imagine a weight at the end of a rigid rod. Fix the unweighted end at the center of a circle. When you rotate the circle clockwise, the pendulum rises in the same direction. Once the circle stops rotating, the potential energy of the pendulum rotates the circle the other way.

[kickercaster18]

Congratulations, I believe that is officially the longest, and most pointless explanation of a weighted wheel that has ever been concieved. Look at you, up there on your pedestal. I'll bet your mommy's proud.

[Grospoliner]

You're accusing me of being arrogant when all I did was explain some simple physics to someone? Why?

[kickercaster18]

Because, it's a lot easier to say "No, it just has a weight on one side." than it is to quote a textbook explanation on quantum mechanical functions to a dude who probably commented without thinking.

Granted, you and I have most likely never met, so I don't know you. But I do know the difference between informing someone on a subject and jumping up and down on someones head tooting your own horn.

[Grospoliner]

It was not my intention to "toot my own horn". I soundly believe in properly explaining any and all scientific phenomena with proper terminology. I supplied what was I found to be a logical deduction from my observation of the wheel while adhereing to the proper terminology as best I could. Simply saying it has a weight on one side wouldn't be properly explaining how it works.

I contributed nothing new beyond what far greater people who come before me have. I enjoy physics its interesting.

[madnesscombat5]

your the one acting superior to Grospoliner. Just becuase you search the dictionary for big words doesnt make you any smarter then him, he simply tried to explain it to someone, stop getting all emotional.

[Grospoliner]

This is just an example of simple physics.

An example of perpetual motion or energy, would be a device that you put zero energy or work into, and get an output of work or energy greater than zero.

Sadly perpetual motion is a violation of thermodynamics, and is therefor impossible. Nothing in the known universe is capable of perpetual motion/energy. Not even the stars as they require fuel to sustain thier nuclear fusion.

[powdermonkey1111]

Perpetual Motion under your definition is in fact in direct violation of laws of thermodynamics, but the true definition of perpetual motion (Being Same amount of work is put out as is put in thus is work put out is harnessed and reinserted into machine, the machine would run forever) Isn't in violation, its just impossible without a 100% friction free environment and machine. This sort of environment and machine has not been discovered yet.

[Grospoliner]

Perpetual motion violates thermodynamics regardless as no machine is capable of producing a net energy gain.

Even in a frictionless, vaccum environment there is always a required initial energy input for any machine. This means its operating at a net energy loss regardless of any inheirant ability to self-sustain the energy requirement it takes to operate.

You could build a perpetual battery for energy storage, but tapping it for work would kill the system.

[powdermonkey1111]

Huh, guess i was under the wrong impression. I thought perpetual motion was just a 100% efficient machine, not a machine that created energy. I do understand that the creation of energy is right out. but a 100% efficient machine could be created under the right circumstances yes? i dont know i may be wrong here as high school was a bit away

[Grospoliner]

A 100% effecient machine would be difficult to produce. Such a machine would covert all of the input energy into useable work with zero losses.

I don't know if its possible to do such even with superconductive magnets to eliminate friction losses. Fuel based machines would be incapable of 100% effeciency as there would always be impurities in the fuel and energy lost during the combustion process.

[Postscript624]

No, that violates thermodynamics as well. The second law dictates that any systems tends towards entropy over time.

[Adkit2]

@Postscript624 No it doesn't, it only speaks of a "closed" system. The closed part is extremely important.

[Postscript624]

@Adkit2 Right, good point and my mistake. I don't know what I was replying to, but you're definitely right.

[kickercaster18]

Nope, it's just off center on the inside. Apparently some dude's idea of being clever.

[lanagual]

I had a toy that did this when i was kid..you know..the 1960's..:)))))

[effedieffedi]

-.-'' il baricentro non centra proprio nullla...

[dannous]

come non c'entra il baricentro? L'illusione che salga deriva proprio dal fatto che le barre più vicine tra loro ad un'estremità tengono il bericentro più in alto che dall'altra parte. Quindi il baricentro tecnicamente "scende" ma il fatto l'estremitàò più allargata sia il leggermente più in alto dell'altra da una falsa percezione.

[Legominder]

OK! :D

[abgecko]

it actually goes down and there is nothing like shifted center of gravity. You can't see it because you can't measure the heigh of the yellow shape. It goes there where energy is lower

[gixxer989]

when i saw the trash cand i knew thats was in italy

[proximu]

maybe needs a cat in there, will not be perpetual

but 9 lives is almost perpetual..... : ]

[trawa35]

ale bajer

[Intermodularian93]

no nie?? :D

[RedWolf3142]

its a load of crap then.

[thespurginator]

no, it's just a neat toy.

[jagara1]

Look closely and you will see that the tracks get closer - this is what causes the wheel to roll back (due to it's funnel shape).

[isketch86]

if you LISTEN what they're sayng, you can hear the same thing (in italian)

[jagara1]

I can't speak Italian though ;)

[whizzmaster3000]

rofl

[ilmatteo95]

@jagara1 basicly he says what the comment above yours says xD

[NoNameWorks420]

@jagara1 You could learn from Peter

[jagara1]

@NoNameWorks420 Who is Peter and what can I learn from him?

[NoNameWorks420]

@jagara1 "I can't speak Italian though ;)"

/watch?v=9JhuOicPFZY

[lucas66568]

@jagara1 i'm italian so i can speak it

[aviatormxpilot]

Dude, you don't have to look closely. The guy at the end gestures to bring the rails closer. Look at 0:18 he points then gesters to bring-em in.

[Legominder]

@aviatormxpilot no

[aviatormxpilot]

@Legominder... YES

[Legominder]

@aviatormxpilot No, there is nothing.

The rails come closer, but it is not changing. It accelerates rolling on the silver sticks, but then it is lifted up rolling on the yellow part, because the rails are not parallel.

[aviatormxpilot]

what's the point anyways?

[Legominder]

@aviatormxpilot I don't know...wanted to have that right...;)

[aviatormxpilot]

PEACE, OUT ; )

[mtracer100]

@jagara1 No, they don't. Read the freakin' description.

[Agathon81]

@mtracer100

It didn't occur to you that maybe the description is wrong?

Take a better look, or just read some of more of the comments here...

[hatae55]

@jagara1 look at the way the rails are mounted, they can't move

[exiledrabbit]

@jagara1 i think thats what the guy is explaining at 0:19

[danielcarmi305]

@jagara1 And it rolls down due to the center of gravity. If the only thing pushing it was the tracks distance from each-other, then it would only roll 1 direction

[woodburyadpost]

@jagara1 You an 100 people are retarded

[jagara1]

@woodburyadpost It's ok, when you grow up there's a good chance you will understand...

[woodburyadpost]

@jagara1 no i understand, its just that people that have to point out the obvious on a video that has more dislikes than likes are retards... such as this vid and yourself... :)

[RedgardH]

@jagara1 duh. captain obvious.

[cloud6060]

@jagara1 Reminds me of a childhood game called shoot the moon. Same concept but with a round metal ball.

[EDALBNUG]

Well technically from the view point of the center of gravity of that device, it is going downhill.

[overunitydotcom]

It actually goes uphill and not downhill!

The guys gave it covertly a gentle push

and then it rolls downhill again back to the start.

As it is a funnel, you have to watch its

contact point !
