Fantastic couple of teaching videos. Thanks a lot for posting. I just watched them with my eleven year old son, as he is off of school due to the Covid 19 virus. He enthusiastically took the whole lot in. Now he's really keen to make some models with his lego bits.

Of course this only supports your point further though, the other guy was just being a whiny bitch about the noise. I definitely never noticed anything even mildly distracting, much less "unlistenable." Probably just some kid who's only ever listened to audio recorded after 2010 with crystal clear audio recording equipment.

I don’t think anything good would’ve came from it if I had that type of knowledge at my disposal when I was a kid to where all I had to do was literally reach into my pocket at any given time and pull out a phone to get any question I could ever possibly think of answered immediately. That would’ve most definitely been a recipe for disaster

28 years old and just understanding this stuff now...... i really wish my school actually taught me stuff.

Nice video , he should mention that when decrease the speed it increases the torque. That's how a car transmission works. When a car starts running it engages the driver gear to the largest driven gear and then starts shifting until get to the smallest one.

Basics of transmission: 1:1, output will be the same as the input. 1:2, output will be twice the input. So one input rotation will be two rotations of the output. Effectively covering more distance in the same amount of time. Speed is distance x time and so you get a higher speed. 2:1, output will be half the input. How does this multiply torque? IDK, it just works.

Best, simplest & most interesting information on gears ever seen ,read or heard. More videos please. Best appetizers for brain hunger!

Videos like this make me miss my high school science classes. Thanks for uploading.

I recommend playing at 1.25x speed. Speeds stuff up a lot.. Good video though!

Very good description of a spur gear.

honestly i was just interested on how gears work and this is a fantastic video!

this totally helps with my wood shop homework!

Stunning to use in class!

I like how giant gears turn tiny gears fast and when you connect another giant gear to the tiny gear, that giant gear spins as fast as the tiny gear. Continue this process a hundred times and you get an extremely fast spinner. One day you could just turn a handle slowly for a minute and get a fast spinning fan for a minute I just love gears

Very helpful, I've been working on something using LEGO and I needed to research how to slow down gear rotation.

Excellent video Sir :)

A really good video. Gives you a good idea about simple machines. People who cannot applaud the beauty of physics and the brilliance of the human mind shouldn't bother watching it.

So...a high gear ratio means, essentially, that it takes more time for your out gear to complete a rotation than your in gear.

Great vid

Amazing video.........thanks a lot...

wow amazing and more efficient than todays videos

good job !

This video is very educational.

4:16 wouldn't puting another red gear in the middle keep the ratio and reversing the left red gear? Its like, the same thing he did in the video but with a 24 larger gear...

Heck yeah, tnx to this I finally learned how wind turbines turn low rpm to high rpm for the generator. Tnx youtube.

well done!!

A really good video

thanks for this now i can do the vacuum cleaner using 5v dc motor

I always wonder how speed reducer works in motor, I mean how do they Reduce the speed. I didn't know that different size of gears will have different rpm. it's awesome. im not in mechanical engineering btw.

Thank you. But do you think you can add other gears than just circular gears? What about corkscrew gears and such.

Adding extra gears also adds extra stress to the motor right?

The first wheel was invented in the age of the Flintstones... well it was more like a rounded up square, but they had it :) At least Hannah-Barbera taught me that when i was young ^_^

So to make speed, you need to reverse the compound combination to the drive train.

I've been googling sprokets and v belt pulleys. Looking a struck mini dozer. Bely drive system, trying to build a mini mover but with tires, not hydraulic.drive.. the belt drive mixed in with chain and sprokets... watched a few kit assemblies... then i caught it .... its the chain drive that sets the center (gear) that goes in the opposite direction.. the chain drive runs constantly with the engine, the belts are hooked up to the lower shaft the other to the middle thus the reverser. Quite intresting... I may build it to look like a riding mower, and just say its all wheel steer and all wheel drive. AWDAWS.. THEY MAKE THESE THINGS....

thank's

thank you useful video

everybody knows that first wheel was invented in Mesopotamia.

Pleace more tutorial for mechanical industry

very helpful

The Internet at its best!!

I don't understand why we put the engine on the smaller gear. For example my quadcopter use the small gear for the engine and a much bigger gear for the propeller. That mean that the engine must run really fast to allow the propeller to do one revolution, it's a waste of power no? Because for a bicycle it's the opposite, the big gear is for the engine (the legs) and the small for the back wheel. If the gear of a bicycle would be built like a quadcopter that would mean that we must spin the pedals really fast to do one spin of the back wheel.

@abdullahatallah9759

The way you connected your engine to the propeller increases torque but decreases speed, if you reverse the gears, the propellers will spin faster, but the torque will decrease..... Personally I think that having high speed is more important than having high torque for a quadcopters, as long as the quadcopter is light and you don't use it for carrying stuff. However, if your quadcopter is relatively heavy, or you want to rig a camera to it or whatever, then you should keep the connections the same, to have a high torque to be able to carry the heavy weight. I hope my reply helped you, sorry if my English is bad, It's not my first language.

@abdullahatallah9759

8 жыл бұрын

I also forgot to mention that high torque is important if you are going to drive your quadcopter in a windy area, because even if the propellers rotate very fast, if you have low torque, the wind will easily manipulate the speed of your propellers making you lose control of your drone

it depends on how much tq your propeller needs. do you know how much resistance the air creates on the propeller? it might need more tq than rpm to create lift. speed/rpm is nice and all, but without tq, you aint moving air
