Machine With Concrete

[legoking97]

Very interesting how the gears closest to the motor take the shortest time for 1 revolution but as it goes down it slows. Suggestion: MAKE IT AS LONG AS POSSIBLE

[VictorVonFox]

reminds me of my electric box that counts the wats that a house uses

[MaxandFredsmum]

Crap

[Sekkiotto]

ULTRA SLOW



[MrYamahaRaptor700]

I hear crickets

[chubyceekcharles]

can you make a tut



[Benandbjshow]

i dont get it how is it concrete

[YukixKrizorMinecraft]

Concrete????!! All i saw was some legos and gears!

LOL!

[Pushdoorpuller421]

this is cleaver, never thought that you could downsize that ganson piece into legos' haha dope

[trueflyingsheep]

what is the torque of the last cog capable of?

[37zeus37]

@trueflyingsheep

slowly pulling the testicles off a sleeping bull elephant

[Dragonicafan]

how long does it take to go around once???

[albinolucario]

i saw this same kind of contraption at the mit museum

[jak9200]

what is this black magic?!?!

[Champy8181]

y strongly suggest, that you dont use,al the little gears, it losses strenghth, thats wy i cant use that tipe of things in mi creations, not mane little ones one after the other, but its cool!!!! nice video!

[kingmarl365]

What exactly does this do?

[orion1077]

concrete won't last trillions of years

[GodlyFantom]

Where does the concrete kick in? O.o

[alextroch]

@GodlyFantom its a recreation of a famous sculpture or at least interesting sculpture called machine with concrete

[darkgaara112]

perfect demistation for mili seconds and sec and min and hour and more hours

[natn0]

why not make it with spiral gears like arthur ganson's construction. there are lego spiral gears you know.

[Vloddamick]

Arthur Ganson made one of these so that if the last gear were free to move, it would make one revolution every about two trillion years.

[darkuran]

@Vloddamick

...and as it is, it would break either the concrete or the steel assembly =P

The torque on those increases exponentially!

[mabrekl]

hey, lets watch it until it spins a round!!!

seriously, how long it takes to make one??

[foxfaction]

Needs more concrete.

[bushputz]

@foxfaction

Could use some cowbells, too...

[TomShloop2]

@foxfaction lol it cant run much slower lol

[TMAK131]

SOOOOOOO Much Torque!

[L3G0nerd]

multiping of the energy 5spared (625 over 1).

[g8tboy]

i know

[spellerdude]

what is the machine doing

[uut0]

the first one spins fast and it slows down its a ganson machine (google it)

[TINKONPOOPKORNER]

hmmm i think the last gear takes one hour to spin

[uut0]

its 25 minutes (its in description :P)

[tropicsmash]

i dont get it

[theyoungster2]

i think this is the same mechanism used in mile counters inside cars!

[mustangfreak12345]

wut does it do and wat is it

[naetoru99]

If u attached a wheel the the last gear the force would tear the machine appart, be careful about your gearing. also, sum1 below said that it could go at increadible speed if the motor was on the other end. well, you see, it would lock up and burn out the motor.

[crusier10]

i wonder how much that could lift...

[cyborgtroy]

Depends on how much force it takes to break Lego plastic, really.

[vuur150]

much force i guess, if even kids play with it, and if you try to get a stuck brick from the other one, you could try some pretty hard things with it, and it doesnt break.... if it would be able to break fast, Lego would suck, thats why many fake legos fail! they arent strong enough

[911suckers]

hey this might sound stupid...

if this process is called geering down... if you stick the motor to the last gear... would this cause the sprocket to the left go at tramendous speed?

[desiredusername]

Mathematically, yes. But in practice, you can't take it very far. The speed times the torque (twisting force) has to remain a constant. So when the speed goes up by 5x at each stage, the torque is reducing by 5x. After just 2 or 3 steps of that, there wouldn't be enough force to turn the gear.

At least, that's what I think. Try it!

[aperson49]

@desiredusername The leftmost gear would rotate at a high speed. But it's torque would be low. So, the load attached to the gear would not be very high until it is unable to maintain the high speed.

[jbellrick]

yes, but there might be much friction fot the motor to keep up with. could jam and kill motor.

[cyborgtroy]

theoretically, but the inertia of the geartrain would make the motor stall for a very long time before coming up to speed, and the way friction is amplified makes it impossible to actually crank it that way without tearing it apart.

[keroberoko]

i doubt it would be able to turn it, while gearing down increases the torque of the final gear, it also increases the torque needed to turn from the other end, the force needed to turn the right gear would be such that the model would most likely break long before it was able to turn anything

[simmo595]

actually its easy its hard from the other end which the motor isnt it seems impossible but its plausible

[Mindstormscreator]

you actually wouldnt even be able to turn the third gear

[bedeone]

there is an unblieveable ammount of torque on the outpu shaft ^^

Too bad it just pulls the bricks appart ='<

[freakoffer]

Wait! Did I miss something? Cause' all I saw there was a gear rotating, and another gear slugging along. Err, take electronics class next year?

[desiredusername]

Huh?

[jobz101]

Jesus!.. read the description... and you fucking take electronics class next year.. its just gears... each one is progresivly geared down more.. As i quote " the last 25 minutes per revolution". which means to see the last cog(Far right) turn 360Degrees the video would need to be 25 minutes long!..

why does youtube attract idiots like you?

[freakoffer]

I'am not a idiot, and rotating gears isn't very entertaining. If you find it entertaining, well go ahead. Go back to your book reading hour.

[jobz101]

If you don't find it entertaining, then don't comment. And dont say things like "Err, take electronics class next year?"...

I'll say it again "why does youtube attract idiots like you?"

Oh, and sort your english out. IDIOT

[fynney1996]

@freakoffer haha can people as stupid as you actually work a computer or did you fall on the keyboard to type

[streetcornerjames]

@freakoffer Too bad your gears aren't turning.

[Givadanger]

put the engine on the Other side... much more fun:]

[jaj040]

Uber torque

[sdpadresfan]

i think i get it. it represents Days, hours, minutes, seconds, miliseconds...right?

[legoman654]

lot of gears....

[eleanorroosevelt1]

looks kind of like a crankshaft

[sycmuzak]

you read my mind :D

[Philpharson]

Hate to break it to you guys but the gears are actualy going slower and slower not faster.... if you reversed it it would get faster and faster.... And probably would rip the machine apart...

[clockwise3559]

OMG THIS IS THE BEST!

[Dtramin]

um, im sorry, im very new to this whole mindstorm thing, but i dont exactly see whats going on here, please dont flame me, but just reply.

[spudrph]

The machine is rotating,but at such a high speed, U see nothing

[Dtramin]

Oh is it?

So those gears are actually moving really fast?

[lbss09]

No, no, no. Like he said in the video details, he is using a gear reduction technique to reduce the gears speed. The first gear is spinning from the motor. The next set of gears are connected to spin five times slower. He does this five times. If he were to add another gear set, the final rpm would actualy be read in One reverlution per Trillions of years. (IE: VERY slow.)

[joecool9900]

Quote Touskov:

but extremly powerfull

THATS WHAT SHE SAID!

[hzhn]

Maybe it would move a plane ^^ A Airbus 380 ? ^^ Not really but it looks very strong.Great Job!

[wurft]

s l o w

[Touskov]

but extremly powerfull

[W660i]

...

[joecool9900]

thats what she said! oh shit!

[mavamaarten]

at the beginning i did'nt see anything.

but then i saw how fast it goes !

[PopeMarmalade3rd]

Hey good thing the motor was put on the right end..... picking lego gears out of your face could be painful!!!!!

[ghostinside]

Actually it starts spiral-bending the axles at such low gearing. They've got an awesome picture example on battlebricks com. (lego robot battles) Cool example though.

[Limpfittz]

made something simular once.. it DID move a train.. ;) (ok it did'nt, but it could move my sleeping cat)

[Metal2626]

than thing is on such a low gear it would move a train...

[Metal2626]

oh man... that thing is on such a low gear, it would probably move a train:]
