Lego Technic Gear Ratio : How It Works

Gear ratios are all around us, but do you understand how they work?
Lego Technic allows explaining all about.

Thought you only play around with physics, but after seeing this, I see that you have a great talent in education. Keep it up!

[@DrEngine]

Thanks!

[@Dark.monster_1]

Thanks for the information 👍

[@tmpace9]

Something else to note-
Sometimes you're given the radius or diameter of the gears. Because we are using ratios those measurements can also be used in place of number of teeth.

[@ravenhack6053]

Gear chains are so interesting,and I love your photography!

[@DrEngine]

Thanks, glad you like it 😊

[@fizzrate]

I thought gear ratios were much more complex. This is a fantastic video and explanation!

[@rabiluaminu792]

Good work

[@rublenoob830]

when the small spins the big the big spins slow and when the big spins the small the small is fast but with less torque, if you make a 1:4 gear ratio it will have 1/4 torque

[@MrShnoz]

10.5!
Great content, love it!

[@SpeedCube2]

Lego technik is the clearest example of the work of gear mechanisms! And you have a pedagogical talent!

[@notimeleft644]

Amazing photography! It looks like an animation!

[@DrEngine]

Thanks! Glad you like it ☺️

[@wolfbrave4866]

This teaches us one thing. The fan in our house is very inefficient it uses the increased voltage to up the rpm when gears ratios can increase the rpm I know when you use gear ratio the motor will be stressed and drain more power but that will need an experiment to see gear ratio vs voltage.

[@doubleperfect2007]

Very nice, good job!

[@backupcreator73]

Amazing video! Now, please, show us how the gear ratio changes the power. Thanks!

[@zeo-nix2875]

2021-2022: wow lego technical constructions! 2050: wow a real car from Lego and even strong and working!

[@blockpartyrobotleague]

Nice production values!

[@DrEngine]

Thanks!

[@ghostg6107]

Love the production quality

[@aidenm404]

You should make a working Lego Helicopter!

[@aidenm404]

*do it*

[@projectstesi7133]

Excellent artwork 😃👌

Thanks!

[@efhi]

Amazing video

[@scratchsuperpower386]

Cool ive always wanted to learn about gear ratios

[@josephrezin5395]

Nice vid!

[@Dark.monster_1]

Thanks 👍

[@hqx_0051]

I really want to do this but idk where to buy, is there any where I could buy on the website for Norway?

[@DrEngine]

Plz try bricklink com 😉

[@Strm987]

thanks !

[@isimyok4219]

where do you get these lego pieces

[@dinhtuan752]

bricklink

[@imsubbingtoeveryonewhosubs5633]

As soon as I saw your last vid, I subbed AND liked it!

[@DrEngine]

Thank you for your support!

[@rabiluaminu792]

Good work

[@DrEngine]

Thank you so much 😀

[@chinmaydeshpande8448]

❤️❤️❤️From India🇮🇳

[@123syamkumar]

I want to buy gear kit and motor for my science project. Where can I purchase ??

[@dinhtuan752]

bricklink

[@ultimateskeleton6887]

Bro i am your old subscriber . I love you bro
Love from india

[@DrEngine]

Thanks, bro👍

[@temediktus1341]

It depend what decimal you will use to calculate, my final answer is 10,48 RPM.

[@Juu_Erkki]

So they spin?

[@apersunthathasaridiculousl1890]

this helps

[@nick-rs1li]

Very nice

[@yunusemrekurku2605]

10,5. I really like it

[@kapilbusawah7169]

Don't read more if you want answers!
Driven gear at start = 157.5rpm
Ratio = 24/8 or 3
2nd driven gear = 157.5/3 which is 52.5rpm
Ratio = 40/8 or 5
Final drive = 52.5/5 = 10.5

[@dinhtuan752]

thanks for the answer
EDIT: the 16/16 is 1:1 so no speed changes from the input gear.

[@Piereletido_el_conejo]

Can you make a lego animatronic moving?

[@bearcub7681]

The gear ratio at the end was a 15:1
Edit: the rpm is 10.5

[@Highland_123]

Its great
I am in czech republice

[@PixelYT-ts2fe]

Yesss know i know the secret of boosting gears

[@2ellas2]

Damn. Thank you for the math lesson

[@DrEngine]

Thanks for watching!

[@Fanny-Fanny]

I make it 2.765x10^8 nanorotations per fortnight.

[@cenreaper9127]

What's the name of the music?

[@wowgggearing]

next: differential split torque equation

[@user-no3vf9ry8u]

Главное, что крутится 👍😀

[@leonashalava9316]

Как обычно очень круто

[@verfix]

[@phimatrajaya2525]

10.46666 great educational content

[@BoicuBuduAndrei]

The gear ratio at 2:44 was 15/1.

[@balamuruganravi9165]

10.5 👌🏻❤️:-D

[@UnkwonGaming]

10.6?????

[@wallin1]

RATIO?

[@ilmannafian9071]

10.5

[@ActiCKiber]

Зроби наступного відео будь ласка турбіну яка працює на пилососі

Dear Dr. Engine and anyone reading i hope all is well. I just want to say that Jesus Christ loves and cares for you. If you haven't done so please accept Him as your savior and Lord. And remember to enjoy and cherish all that is good and right in life for we only get one life and we don't know what tomorrow will bring.
