Allow me to thank you so much, I have searched a lot and studied a lot books, sites, notes... but I never understand like I did with your video . amazing what you did in just 10 mins while I spent hours try to make sense of what I'm learning. thank you sir.

Thank you! Share with your friends! :)
The free hand drawing @ 3:57 , just wow
I was shocked on how well you define and explain the different categories gears have
This was just awesome. Never thought anyone could explain like this. Thank you very much for sharing !
Amazing video and great drawing skills. Cheers
Thanks you very much sir Love for Pakistan. I am student of mechanical engineering. I can't understand it from any book. You explain it very simply. You are great sir.
wow! amazing tutorial. Thank you sir!
thank you this pressure angle is quite well explained here !
this is gold
It would be great if you published the notes that you used somewhere, love the videos
Thanks for video but the last example gives the impresion that a speed increasing drive is simply a speed decreasing drive in reverse, its not. There are factors such as: 1. The length of the lines of access and recess along tje line of action which are coupled to lubrication characteristics. So called, non-standard gear geometry needs to be considered. 2. Gears have a natural frequency which needs to be considered compared to their operating speed. This is more critical in speed increasing drives. 3. Vibration, as above, this factor also plays a bigger part. Analysis os needed to ensure that the gear train's operating speed is not in line with its natural frequency.
Can you do gear profile shift?
My professor is a shit, he only teach us how to use the formula to calculate without diagram.And let me super confused which letter means which item.And for the letter which is huge different with the textbook .Like he said Pd means diamtral pitch and Dp means diameter of pinion. Damn always cannot distinguish them with out diagram.Thanks for your video to save my final exam.
Hello, would it be possible to get the notes for this video?
Jesus, this video is beautiful.
Hello Sir! Can I get the notes? It would be helpful if I could get. Thank you

@@LessBoringLectures Love your videos, great job! I am also interested in getting a copy of your notes for various lectures. Do you publish all your course notes in a pdf?
Okay now do rack and pinion
who does the art for your vids?

You used be the best Mechanical Engineering student I believe.
Are you Filipino?
