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

[@Shosk]

you just turned 2 chapters into understandable work in under 13 min... Thank you!!

[@the_maker1841]

thank you, this was a clear, simple cut of what I needed to go over to review for my test.

[@husamali1306]

Thank you! ❤️

[@muhammadabdullah3467]

Man you are GOATed. Thank you very much.

[@26382877]

Proof that board teaching is admirable

[@Tilpho3373]

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?

[@LessBoringLectures]

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.

[@ridwanhusainishraq]

Can you make a tutorial on how to draw an optimized structural diagram and ray diagram of gearbox

[@chrisvincent782]

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.

[@thenightowl4518]

Totally agree. It's difficult to digest all the information when speaking at this pace.

[@AJ-et3vf]

Great video. Thank you!

[@yasinaydemir4786]

isnt it necessary become clockwise rotation of the gear 9

[@more2much696]

where can we send questions,, we are having trouble solving

[@KevinMa-oy2bz]

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?

[@notime4lag624]

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

[@LessBoringLectures]

Yeah, it's not literally equal to n2/n5. Should be an "equivalent to", for calculation purposes.

[@paulhammons7077]

Thanks KZbin... but yah if i have the time ty

[@ryanking9884]

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

[@Rcpasionplus]

Which software uses to make the drawings?. Thanks
