Timoshenko Beam Theory Part 1 of 3: The Basics

[@jerrysmith9780]

As an engineer, rarely we get a history lesson and timeline of how these things developed. This was amazing!! Thank you so much for sharing this. Very interesting for sure!!

[@ugoamaldi8056]

Sir, you are a real Master in explaining clearly and pleasurably extremely complex topics. From an educational point of view, this is equivalent to a college lecture. I am an aerospace engineer and your knowledge is outstanding, thank you kindly for your efforts.

I have been waiting for a new video for months. I am planning to watch each video in this channel. I had already watched most. Thank you sir!

It's been a while since the last upload. The content just keeps getting better and better overtime. This is a really good topic for a video! I have been reading Timoshenko's books and wanted a more in-depth video explanation. Thanks for this!

[@sagsolyukariasagi]

If I may ask which one you have been reading to ?

[@xelonix_]

@@sagsolyukariasagi Currently reading the History of Strength of Materials, and also The Theory of Elastic Stability.

[@nicolaiharvik]

Absolutely fantastic work, sir! I appreciate your focus on initial assumptions; it really helped me get a much better grasp of the theory. I wish more professors took the time to derive and explain the core ideas presented.

[@nicolasramirez3944]

I am SO happy you are tackling this! Love your approach!! : ) While I appreciate your inclusion of Ehrenfest (whom I've never heard of), I more appreciate your praise of Timoshenko, who I'm currently infatuated with.

Do you guys know what his educational background is? Is he a math or engineering major or both. He explains things so well it makes you think he's a professor, definitely better than some of my professors.

One of my favorite textbooks is "History of Strength of Materials" by Stephen Timoshenko. Highly recommend if you like the history lessons here!

[@iaincrawford5472]

Brilliant, thank you very muchfor this!

[@mathunt1130]

I'm looking forward to seeing how this works.

[@satrajitroy9603]

Are the remaining parts, 2 and 3 out yet?

[@Freeball99]

They will be released over the next couple of days.

[@wolfsiken7864]

Excellent presentation. The illustration starting at 20:52 may not be correct.

[@Freeball99]

It's probably not the best way of drawing it. I'm not trying to show direction of the shear strain here, just the fact that the shear is consistent along the cross-section.

[@hesammortazavi9371]

An irrelevant question. Could you possibly provide a tensor mechanics reference? My understanding of the tensor is unclear; specifically, I cannot understand the difference between matrix and tensor. I looked up many videos and references but almost all of them are unclear.

[@Freeball99]

Sorry for the delayed response, but I just saw this. I do not have a specific reference for explanation of tensors, though there are many KZbin video on the subject.

5:32 but there’s such a country in the world, where mechanical engineers don’t know the name of Stephen Timoshenko (Степан Тимошенко), where he’s not mentioned in lecture courses, nor in books (yeah, his books are not cited, not listed in bibliographies-for already more than a century), where no university teacher says students Timoshenko’s name (most likely because he doesn’t know himself), where Stepan’s contribution in science is abandoned, forgotten and ignored ... and, that’s why people studied in that country don’t know anything more but Bernoulli beams, and in fact even that model isn’t mentioned as “Bernoulli’s beam” there, simply as “a beam” could you guess that country?

[@Freeball99]

I have no idea.

[@playmanky]

Good good goood. Thank you sir!

[@Freeball99]

Welcome!!

[@jeromedubois4038]

Could you recommend me a textbook that would perhaps cover this whole series. I have several books on mechanics of materials but non of them deal with Timoshenko beam theory (and other subjects such as vibration). I also took a finite element analysis class in which the delta operator kept coming back, but my teacher completly flew over explaining its nature and why it does what it does and would also appreciate a good reference textbook for that as well. Feel free to recommend a book for each topic in this series ;) Thanks in advance @Freeball99 This series is an absolute gem by the way.

[@Freeball99]

"Solid Mechanics: Variational Approach" by Dym & Shames tends to be my go-to book for this sort of material. www.google.com/books/edition/Solid_Mechanics/rTw_AAAAQBAJ?hl=en&gbpv=1&printsec=frontcover

All you have to do is work with models.
