Perfect thanks for that explanation

Thank you very much! This is the video I was looking for. Great video!

[@RB20071]

Thanks a lot, very simplified and easy to understand!! I appreciate you makimg this video!

Thank you very much I was looking for it and I got a right video 🙏

[@lunditv]

so excellent

[@nats50]

Informative.

Really great video .

Thanks Wadi

[@efremgebrehiwot8695]

you are my favorite love your math

[@fade3546]

How did you get that X n 1? Btw nice explanation 😀

[@muhammadander6368]

tusen takk

[@Thomas-fc6gf]

Jenn can you please explain why at 12:57 you put the x in the denominator instead of the numerator for the proportion? I really need help understanding that. Is there somewhere i can message you directly

[@jennlexmond5738]

I think you mean for the speed calculation? Speed is inversely proportional to the gear ratio. So, if I set up my gear ratio as output/input, I have the speed side of the equation as input/output. I have the input speed, I'm solving for the output speed. This means my "x" goes in the denominator. Sorry for the delay in responding!

What softwar do you use to prepare you lessons?

[@andrewlawson3798]

Just a ratio. So what this tells you is that your drive shaft will turn 4.37 times for one full revolution of your final drive or rear wheels

Hi Maam how to find suitable numbers of theeth pairs on the ratio For example I have 3stage helical gearbox for 500 center distance and their ratio is 108.755=109 and there center hight=195 so how to find their suitable numbers of gears and pinion teeth pairs

[@ironmike7160]

So 4:32 the input 20 teeth is 1.5 and output teeth 30 teeth is 1 ?

[@mds950]

👍👍👍

Äzi eller bruning?

[@ironmike7160]

I love machines, but the mathematics would rack my brain

[@jennlexmond5738]

vice versa for me.

[@h7opolo]

15:23 "fewer revolutions," not "less." i knew you weren't smart.

[@jennlexmond5738]

Or I'm not good at grammar. All people have strengths and weaknesses. I hope the mathematical point still comes across despite my poor choice of words.

@@jennlexmond5738 yes the mathematics are superb. Most of us appreciate your work. Thank you.
