@@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
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.
As a maintenance mechanic in a casting facility, its nice to refresh and relearn this stuff. These videos are more for engineers, but its always nice to know how things work as a maintenance technician.
@@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
@@orange9807 Yes there seems to be no fulcrum. But space time is being bent and it takes a lever to bend anything from straight to curved. But the difference of pressure or speed on opposite sides of anything can cause it to bend also. Not sure how this ties in with distance/power though. Anyway not really making much sense. Thanks for listening though.
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
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
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!
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.
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
@@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.
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
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
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
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?
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
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
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.
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.
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?
Yes it can, you can't tell the height of each gear to know if they are stacked or interlocked. You should focus on how things can work, that's an Engineering Mindset.
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.

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.
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.

U r the best teacher I have ever seen before 😂
Clarity of understanding and simplicity of Presentation makes better understandability?
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 so much love this channel.
You really do explain things perfectly and I appeciate your video and also your gear calculator, excellent stuff
Gears really used to grind my gears. Thanks for explaining clearly.

unless you can calculate with the resistance
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.
Nothing can be perfect than explained in this video. Awesome work.👌👌👌
Now things make sense,
Great vid very helpful and informative, great presentation.
That was so good
I had misconception regarding these for so long
Thanks!

@@RithwikVadul it's alright bro
The Best as usual, thanks a lot
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
im just watching this to learn how my bike works, and now his making me calculate gear ratios
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
got to about 5:00 before I was too baked to continue but I'll be back at this video again soon

I would like to see planetary gears also as simplified as this one!
👍
just the information im looking for xD. all those books got me confuse with their formulas. just wanted to know the concept between gears .
Great work
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?
Thanks to this video because no I know how to make a car robot move faster and how to make it have more power.
Awesome. 👌
Sir, will the gears in the thumbnail pic rotate assuming the two upper gears have same diameter...🤔🤔
No, they will not

Amazing amazing amazing amazing thanksss
How come every topic you teach is so clear
AMAZING!!
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.
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!
Make a video about Synchronous motor
YAY! Physics!!!!!
Very good.
3:27 Compound gear train.
Many thanks for the video... If you please make a video about the use and difference of Newton and Nm.
Thanks 👍
nice and simple
Please change the thumbnail of the video as you have a 3 gear system which in practice they don’t turn.
Yes it can, you can't tell the height of each gear to know if they are stacked or interlocked. You should focus on how things can work, that's an Engineering Mindset.

What do you believe is spelt wrong?
@@EngineeringMindset "gar ratios", "why we need gets". Great video as always!

Yeah sure, we did cover this briefly in time delay relay video, have you watched it?
I have subscribed but didn't download the gear calculator....How can I get that Excel workbook please?

@@EngineeringMindset Thank you
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.
Bless you.
Isn't it the ratio should be driver gear to the driven gear?
