Im not sure if the wind pushing on the scale is a good measurement of thrust, but then again, it’d be hard to mount the propeller to a scale unordered to measure the actual push and still be able to hand crank it. An excellent video nonetheless, you have built some impressive gear inductions!
As long as it's consistent it's a good comparison
God has said in the Quran:
{ O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 )
[He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 )
And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 )
But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 )
And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 )

Yes it is cuz to make an aircraft that thrust is going to tell how much the aircraft can weigh or how much weight this thing can push
@@ahmdabdallah5811 who
he is obv drunk he is now using the drill butis not wvwn telling us what the power is...and like u said u can not mesure something sooooo close where duz he think the air is going and i new that fan with plastic was rojnd it would be worse for the thing to makw more power u need a place foe the used up air to go well he was not lettin that happen so this video was verry silly sorry but am hust been honest
The build quality on these seems to be getting higher
The more you 3d print the better your prints start to come out.
Lesson learned "sharp & light blades provides more thrust
@Ribbat Ali Well from what I know, which I may be wrong, the weight of the propeller isn't directly tied to the force of thrust provided as the force of thrust is not from the mass and speed of the propeller but rather the mass and speed of the air it pushes. If the propeller weighs less, it should be a lot more beneficial as what matters is how much air it redirects, and those should not be directly tied from my prior knowledge. Should go without saying though, sharper blades can cut through air much better.
@Ribbat Ali well I think at least that the rotation speed isn't tied to the mass
It's a hand crank fan for emergency use .
Yes but for the whole building
@@gamingbuildingandcubing5644 Why not 2 skyscrapers?
Awesome choice of background music there! The gear wind up sound is sexy as always lol
Thanks for helping me in my school project idea thing
Do 8 gears with a propeller at the end! :3
I love this video
Try adding a flywheel at 1:1 or even gear it down as well, this should help a ton with keeping the whole mechanism going at a stable rate + making it easier to reach higher speeds and keeping it there.
you should stablelize the assbly by bolting it down to achive maximum efficiency because you can lose power by just wabling
Yes, I was about to comment that, but more for his security like you have to have balls to put your naked hand in an asebly that has gears spining at over 600 rpm
Like, make us a favor and use protection gloves or better yet bolt that asembly down
Rubber feet and a rotating crank handle will go a long way for quality of life.
So brilliant, wow,ill bet you could invent a yelpingstreacher catcher.
Can you include the weights of the propellers? Weight to thrust ratio would likely better represent a propeller's strength.
Wow Nice video thx bro
IMHO, you should’ve clamped down the gearbox to the table to guarantee a defined and consistent distance. The flight pioneer Otto Lilienthal constructed horizontal rotors for different wing profiles, rotated these with a constant angular momentum and measured the weight reduction caused by the lift the rotor generated.
With my own experience with gear box's the further away from the fulcrum the place you aply force, the more easy it is to spin a gear box
that is true but the further away the more work needs to be used in turning it at speed
I don't know why but I was satisfied when I watched this
Torque you should try that on the other way this thing is cool Dude 👍
Nice use of Wintergatan music!
Music by Wintergatan?
Excellent choice
This is amazing! Could you share files of this thing?
Please make more vedio on this propeller with more gears
If you have a lot of gear, just enlarge the handle a bit and apply a little force
@@AliasT.K but then you have to move your hand further because of the larger gear radius. A motor would be best because of a consistent torque
good idea,,👍👍🤫🤫
Next video idea: Hand crank powered airplane
Now you can use one of @MajorHardware fans design as a propeller :)
Is it just me or was anybody waiting for him to add more gears to make the fan go faster?
I really enjoy this relaxing music🤤
Ngl the background music sounds like the background music of a funeral slideshow
Should have used a motor for consistency. Good video though :)
Nice but more work to the gear box and mounting the test rig and powering it with a electric motor I bet those improvements will have better scores next time you try and nice work
nice
Just make the gearbox atached to the big scale white thing
I like the video, not a fan of the background music being so incredibly loud compared to the video, i kinda want to hear the gears make noise.
If the gears were a little bigger and more stable, you could do it on a bike with a propeller ??
Can you try it again with more gears?
That's a LOT of gears...
How do you compute for its gear ratio ?
where can i find these big gears for my project ? ?
What would happen and how fast would they go if he . Connected all the gears that he has into one
Wow to calculate the speed?
Just wondering, did you ever try the fans out on yourself?
If i can build a system based your design in this video .Can i use this system for reach to 100.000. Rpm ?
I want use mettal for shaft and gears .and use aluminum for propeller. Please answer me.thank you
Are all gears the same size?
Where is the scale on the handle?
I hear Ender 3 humming in background
Why not make a more stable base for it?
If you pleased, Can I understand, Can I use it for a mechanic work....??
a força que tem que ser medida não é a frente do hélice e sim no eixo do hélice.
Aur sir gear retio 100000:1 me motor ka taurk kitna hona chahiye
That's soooo good!!
And could you give me your way of contact in order to contact you
Should miniaturize it and turn it into a fan for staying cool in the summer.
Used to do the same thing with mecano 50 years ago! Nothing new
it would be nice if you could dising a gear for a bike to make it go faster, for people who only use bikes to go to work.
bisa buat generator angin
Needs more bearings
Can we generate electricity with that?
2:52 Starts
i want this on my bike lol so speed go brrr
Use grinder turn 3d gearbox
I couldn't help but notice you put bearings in the gears that are attached to the shafts and they will never be able to move, but failed to put bearings between the spinning shafts and the housing.
NOOOO MY PATENTED DEVICE I DESIGNED 2 DAYS AGO
The boost gearbox could be held in a box scaled to the golden ratio (infinite spiral)
That aint how oyu measure thrust man. You need to heve the propshaft push on something to measure how much force the prop is exerting on it. Cool idea tho!
Who says bugattis(veyron mainly) can blow your hair. Nonononono this can
مدهش🇰🇼
You have to make little that fan little far from gearbox for better results
*Alternating current generator*
POV: propeller fo brrrrrr
Bro..i download ur free gear box zip file which is 3 mp ...how to open it and which application should i use for that file...can u explain it.
It contains STL files that you can import into CURA to prepare for 3d printing
@@3DPrinterAcademy got it thank you
Jiski speed light speed ke braraber ho ya kuchha kam ho
2:16 there are more than 10 small gears then also he just pickuping one by one
this music reminds me of The Sims 1's...
More sipn
Can u prepare helicopter with them😃
Faster savi faster gearbox banaye
Why use wood screws to the plastic tho
What would you use
It's the eaisist thing to get for them and it works well
he didn't have any sheet metal screws ;)
Well nice video bro
But my name is not on this too🙂
Why would it be?
@@jerrylindstrom3323 you didn't see the live video
@@BMG.CHANNEL no?
i can make a gear system and the mitor is out of a dvd player but it can lift 280kg its run 8 gears 4 plastic gears 2 are aluminian and 1 is steal and the last 1 is hardend steal it takes 35minz for the machine to pull up the weight...its endless u could get a computer motor to lift a house
Wish he would have attached the drill
Now you can safely lift a tenth of a pound.
영상 찍는 동안 3d프린터 돌아가고 있는소리 들리네
attach a siren
Lost me at : on accident 🤦♂️🤦♂️😂
Is anyone else annoyed that the screws aren't sitting flush?
20 tooth? Plase
Me khud bhi Koshish kar raha hu
When he was assembling the handle all the move so close to the camera made me incredibly nauseous
Attach
A drill
Está bien el vídeo pero no me gusta la música
Put a motor on it
Par uske rpm 300000000rps ho
Rpm.
So anybody with a 3d printer and a camera can make a video huh?
ATTACH
SUPERFAST
MOTOR
INSTEAD
OF HANDLE
Please please next time use a clamp
Okay but can it defeat goku?
I think the video would be better without the music, just the sounds of the video
यह जी कहां मिलेंगे मैं इनको मंगाना चाहता हूं
Jawab dena sir
These aren’t gears these are obviously washers
music is too loud
это так не работает
