I must "reduce" video for 0,75 speed , to try "reduce" his fast talk, and finally I understand how planetary gears "reducer" is work, great video
you just turned 2 chapters into understandable work in under 13 min... Thank you!!
thank you, this was a clear, simple cut of what I needed to go over to review for my test.
Thank you! ❤️
Man you are GOATed. Thank you very much.
Proof that board teaching is admirable
With the planetary gears when you write ( (nL - nA)/(nF - nA) ), is the speed of the first gear (nF) referring to the gear it rotates about at its base? or is it generally the driving gear that creates the motion?

Gear that drives the system. However, if you set up the equation correctly (meaning, you keep the n to N ratios inversely proportional, and not worry about what is defined as train value "e"), it doesn't matter which one you define as first and last gear.
Great video. Thank you!
Can you make a tutorial on how to draw an optimized structural diagram and ray diagram of gearbox
isnt it necessary become clockwise rotation of the gear 9
where can we send questions,, we are having trouble solving
on 7:30 if (n2-n3)/(n5-n3)=n2/n5 doesnt n3 has to be 0 for that to be true?pls help me super confused

Yeah, it's not literally equal to n2/n5. Should be an "equivalent to", for calculation purposes.
I want to help you with something, when you speak, take a "one onethousand" between sentences. it takes a sec for what your saying to be comprehended by the listener, especially this kinda thing.

Totally agree. It's difficult to digest all the information when speaking at this pace.
Just a confusion pointer. you claim that n5 = (N4*N2/N5*N4)*n2 but isn't n5 influenced by the angular speed of the arm n3?
Thanks KZread... but yah if i have the time ty
Which software uses to make the drawings?. Thanks

First education video I have had to slow down because you talk so fast. Watching the video is stressful 😅
