the triple geas in the tumb nail and chanel avatar noooooooooooooooooooo
also cool vid tho, love it
@@olagarto1917 the three gears can work, you should focus on how things can work, that's an Engineering Mindset. Consider the depth of each gear, maybe they are staggered and not all touching
as a gear, i can confirm this is how we work
lol
😂😂
lol
As a work, i can confirm this is how we gear
Lay off the lsd brother
I have been teaching physics, engineering, and robotics for 30 years. I have watched thousands of videos explaining these concepts. These videos stand out as exceptional in their quality. The order of concepts presented and the clarity in which they are explained is stunning.
Furthermore, I have now watched no less than 30 videos on the Engineering Mindset, and they are all of this quality.
U r the best teacher I have ever seen before 😂
Gears are just levers like any other lever where it is a trade-off of distance & power
Correct how ever you still do the same amount of work as work is equal to force multiplied by displacement.
Is Gravity also a gear or lever and if so then why do they say that Gravity is a weak force when it acts at such incredible distances.
@@swift4856 I do not fully understand what you mean by Gravity is a weak force at great distances. Gravity is not a gear or lever but is an invisible force that pulls objects towards a bodies centre for example gravity on Earth pulls objects like you and me towards the centre.
I’m assuming you’re asking “Why is the gravity force so weak when we are higher up away from earth”. Simply put the force of gravity acting on a body (e.g a human) decreases as the distance between the body and earth increases. My explanation is very basic for a better understanding look into Newtons Law of Gravitation.
@@orange9807 But isn't it just like 2 or more objects being levered towards each other because it is a centripetal force. It is just a question I have always had because the force seems to reduce with distance the same as gears do. I realise the objects are causing the force themselves but the lever seems to be space/time. Sorry but no explanation of gravity has ever satisfied me. Sorry to be a bother
@@swift4856 I would argue that gravity isn’t like 2 objects being levered together as then it would require a lever. The force of gravity keeping an object in circular motion is an example of centripetal force.
Even I only have a very elementary knowledge in physics. It’s be great if someone with more knowledge would charm in.
P.s you’re not a bother mate
This doesn't confuse me as much as it did as a kid when I first start looking at things but sometimes it tries to.
I couldn't 'get' why the small gear on a bicycle was the hardest one until this video showed the short and long wrench example. Instantly understood.
Nothing can be perfect than explained in this video. Awesome work.👌👌👌
Now things make sense,
Great vid very helpful and informative, great presentation.
You really do explain things perfectly and I appeciate your video and also your gear calculator, excellent stuff
I so much love this channel.
Very good video. Great Job. Love this channel.
Thank you, dude! Very clear explanation.
That was so good
I had misconception regarding these for so long
Thanks for the content
This is gonna be a good one
More videos with gears!! Excelent video
The Best as usual, thanks a lot
I wanted this video thanks for it u are truly one man university 😁
I was literally just looking at what a gear hobbing machine cost when I came across this video. Doesn't look like I'll be able to afford my own machine any time soon, but I can pay shops to make me gears. So maybe with the help of videos like this, I'll be able to size my gears correctly at least. Thank you!
Beautifully explained
I so much love ❤ this channel
Great Work 🥳🥳🥳 Thank you 💜💜💜
Hello, thank you for the effort and great content you are providing, I would propose a series about solar panels and circuites for houses, of grid, on/of grid and on grid with energy pumping in the grid. Thank you.
Seen our new video on HOW SOLAR PANELS WORK in detail ua-cam.com/video/Yxt72aDjFgY/v-deo.html
Great
Thank you 😊
great. please make the next one also about gears
Gears really used to grind my gears. Thanks for explaining clearly.
in the real world resistance is included so you cant just calculate it if its more than 3 or 4 gears after that you have to include resistance
unless you can calculate with the resistance
Great work
I was waiting for this video for so long for my children. Thank you! 👍
Only if they are 8year and up and are relatively intelligent.
Younger than that need more graphic explanation and a toy (that they like) application.
Great explanation sir... You are good... 👍👍👍👍👍
Very very very good. Thank you
Thank you for the video!
best education engineering channel
Simple explanation 👌
Awesome 👏 video
Very informative! I always wondered why the torque changed between different gears.
I thought it was just common sense
Thankyou sir very well explained
AMAZING!!
Awesome. 👌
nice and simple
Very good.
best channel

Thank you
Bless you.
Thanks 👍
Not telling you how to do your job but rfSin(theta) might be a better choice for explaining torque, because then we calculate for odd angles and not just sin(90)=1
Good example
Awesome
Gears are my favorite parts in a machine ⚙️✨
At 4:54 It's not required to calculate the ratios for A to B and B to C only A to C. Later at 5:29 when D is added only the ratio from A to D is required. Since A and D both have eight teeth the ratio is 1:1. It doesn't mater how many gears are involved, only one calculation is required. This doesn't apply with gears on the same shaft at 6:15
Hello sir, could you please explain planetary gear system?
awesome
Do planetary gears next!
Awesome video! Do more videos about mech engineering, please!!!
thanks
Thanks!
Thank you, Muayed
Nice
just the information im looking for xD. all those books got me confuse with their formulas. just wanted to know the concept between gears .
Please make videos on DX system ahu selection
Am always here learning ❤🔥
Make a video about Synchronous motor
So I have to ask if you don't know what the input rpm is but you know what the output and what the ratio is. Can you calculate the input?
this helped me with exams
im just watching this to learn how my bike works, and now his making me calculate gear ratios
In the compound gear system, why does the torque between b and c have to be the same ? I understand why the RPM is the same, but why torque is the same ? Can anyone explain ??
Because gear b and c both are mounted on same shaft therefore gear b and c has same rpm . And your next question why it's torque also same ?bcoz it's gear ratio is Same . And aslo they mounted on same shaft
I have the same question because if turning force (ie torque) is force x distance, why doesn't the larger gear (C) have more torque?
@@anayaj402 Yes torque = force x perpendicular distance to axis. Look where the force is being applied... to gear B not to gear C. So the torque would be the tangential force produced by A multiplied by the radius of gear B. Gear C is just along for the ride. It all depends on where the force is being applied.
When you do the very first animation of the smaller red gear and the larger blue gear, why does it look like the larger blue gear is spinning 2-3x faster than the smaller red one? Is it just me or shouldn’t that blue gear be going much slower? That part really confused me
Many thanks for the video... If you please make a video about the use and difference of Newton and Nm.
I learned a lot from you, and i would wang to become an engineer one day. What job do you think is better for the long-term: electricall or mechanicall engineer
Choose the one you enjoy the most, if it's what you want to do with your life, you must enjoy it.
@@EngineeringMindset I enjoy both, but i think electricall is my cup of tea

Hi Paul' your channel is missing the explanation of glycol chiller system. Kindly add it we need it so much
This is like a whole lesson from university summerized
I would like to see planetary gears also as simplified as this one!
👍
As a 9th grader who was always confused by gears, this vid cleared all my doubts.
as a 9th grader i deeply regret wasting all my time in 6th and 7th playing games due to corona . before corona I read a lot of stuff which are basically WAS learnt in 8th i really wish i had used my time in 6th and 7th wisely to learn trigonometry this thing i watching now maybe learnt exponents and algebra and rational numbers instead of the other stuff i learnt in 4th and 5th
sorry for my shitty typing im real bad in typing
@@RithwikVadul it's alright bro
I still can't quite understand planetary gear and its ratio. Can you please explain it?
YAY! Physics!!!!!
got to about 5:00 before I was too baked to continue but I'll be back at this video again soon
As the rookie in the room, how do generate enough torque for a robot arm to suspend the robot in the air? We tried direct drive, and when the arm swings up and hooks on to my finger, there doesn't seem to be enough torque to make the robot move at all. If I add gears, assuming I'm understanding this correctly, I should be able to suspend the robot with that same motor given the right combination of gears?
Also, would adding a second motor, that puts out the same power as the first, be helpful?
At 7:45
It has more torque not less. Right?
Yes i suppose so maybe a mistake. It has to be greater since rpm is lower than A
Thanks to this video because no I know how to make a car robot move faster and how to make it have more power.
If ratio = teeth of output/teeth of input, then the ratio should also be equal to RPM out/RPM in. If that's the case, then shouldn't RPM out be equal to ratio x RPM in?
Correct, that's what he said.
How come every topic you teach is so clear
多謝！
Thank you!
I have subscribed but didn't download the gear calculator....How can I get that Excel workbook please?
There's a link in video description, it'll be auto emailed to you
@@EngineeringMindset Thank you
Will you make a video abot logic gates someday?
Yeah sure, we did cover this briefly in time delay relay video, have you watched it?
Sir, will the gears in the thumbnail pic rotate assuming the two upper gears have same diameter...🤔🤔
No, they will not
I am assuming all gears are touching each other
Take any individual gear and impart any clockwise or anti clockwise rotation, you will always get 1 gear opposing the direction of rotation of the driver gear !
@@kevinsalmador739 I think I have figured out ,gear on the left will be compound gear , and upper right gear and lower right gear are separated but both are touching left hand side gear. In 2D it appears as though two right gears are touching but in 3D , the concept becomes clear.
Did anyone else realize the gears on the video thumbnail image will never work? Great explained though.
They could work, if they were staggered. You're assuming they are all interlocked but they might be different thickness and offset from each other
Help me, I can't identify the name of the style of gear that looks like a quarter of a full round, that can lock into just a flat gear block!
is there a way to increase both rpm and torque without losing values?
I don't think so because Power = Torque x Angular velocity (RPM). So to increase both the power would have had to increase, which means more energy transferred every second out of thin air.
Thanks for making videos other than electrical engineering. I love all the videos you make but since I am mechanical engineer I love this video. Please also make a video of how to design a gear.
See our new video on how to build mechanical versions of electronic circuits? Watch here: ua-cam.com/video/Zv9Q7ih48Uc/v-deo.html
I don't understand what is the meaning of torque in the gears where is the length and where is the force and why the big gear has a big torque and the small gear has a small torque what is the relationship
👍🏻👍🏻
Now how can i use this to build a tank?
Video description has 2 spelling mistakes. Otherwise, great video with clear and practical explanation. [DiowE]
What do you believe is spelt wrong?
@@EngineeringMindset "gar ratios", "why we need gets". Great video as always!
@@EctoMorpheus Thanks, now changed.
2:25 This reminds me of transformers are they somehow related?
Isn't it the ratio should be driver gear to the driven gear?
