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.

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.

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

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.

At 7: 48 you said gear C would also have less torque than gear A because of gear B. but doesnt gear B have more toque than gear A. so it wouldnt it have more torque than gear A?

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?

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?

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.

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!

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?

just the information im looking for xD. all those books got me confuse with their formulas. just wanted to know the concept between gears.

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.

Thanks to this video because no I know how to make a car robot move faster and how to make it have more power.

Many thanks for the video. If you please make a video about the use and difference of Newton and Nm.

Please change the thumbnail of the video as you have a 3 gear system which in practice they dont turn.

Did anyone else realize the gears on the video thumbnail image will never work? Great explained though.
