your channel is a GOLD MINE . thanks for the great content

[@TheBomPE]

I appreciate the encouragement! Thanks for watching!

[@cuetoestradaandres2570]

I'd love if you were my teacher haha
You're so great, mine just left us 1 exercise during quarantine and never saw him again, not even to explain
Thanks!!!

[@TheBomPE]

I'm glad I could help! If you come over to Louisiana Tech University, you could take a course with me and then decide if you really think I'm that great, ha ha. My own students don't always think so. Anyway, thanks for watching!

[@cinnamonbrawl831]

Honnestly thank you a lot for your content and taking the time. I'm following this course this session on online class, but it's nothing compared to how well you can explain it!

[@TheBomPE]

You are very kind! I'm so glad you are finding my videos helpful! Thanks for watching!

[@alirezasameti4042]

Perfect explanations for all those details! Thank you!

[@dogansahutoglu2073]

Thanks, Dr. Micheal. Especially, the last example's been very helpful.

[@TheBomPE]

I'm glad you found it helpful! I also appreciate your support of my channel! Happy Easter!

Amazing lecture, very helpful and so well explained. I just have one question, (at min 8:00) if 120° degrees apart is better to properly constraint the movement of the shaft, ¿Why manufacturers decide to use 90° instead of 120°? Thank you for your time!

[@josefsanchez62]

Can you provide information on the shaft penetration effect on the torsional stiffness values?

Really funny thing : As a teacher in Canadian college, most of my students know the metric system. Yet we force the students to use the US customary units instead of metric, because it is not common in North America. Seen you teach with metric system make it weird! 🤣

[@TheBomPE]

I actually use both systems, because both are important to know. In addition, routinely having to use two different unit systems forces students to de-naturalize from any one system, so that they can (correctly) view all unit systems as being constructed, fairly arbitrarily, by humans. They are essentially all convention, with little or no absolute connection to immutable physical things or concepts. I always tell my students that I didn't really understand English grammar very well until I tried to learn Spanish, because it forced me to de-naturalize from my original language. Something similar happens with units when you are required to be fluent in at least two systems.

What book are you referencing for the press fit? Looking for a textbook style explanation with formulas to calculate press fit between different materials.

[@samsonmkrtchyan4037]

All the way at the end you found the stress at the value of 225.21 MPa. I think (not 100 % sure though), that this stress on the stress element should be the shear stress, instead of tensile stress.

[@TheBomPE]

No, it is a tensile stress. In some texts they refer to this kind of stress as "hoop stress" which has normal (not shear) orientation.

I looked him up. Seems like a cool dude.
