Understanding Buckling

[@TheEfficientEngineer]

Thanks for watching! Here's a link to the short video on Euler and the Self-Buckling Problem on Nebula - nebula.tv/videos/the-efficient-engineer-euler-and-the-selfbuckling-problem!

[@MSA206]

You are saying “ Pcr doesn’t depend on the strength of the material at all” but it is a factor of E and E is the indicator of the material strength

[@TheEfficientEngineer]

E represents the stiffness of the material, it doesn’t tell you anything about the strength of the material.

[@MSA206]

​@@TheEfficientEngineer Thank you for your comment and taking the time. You're right that E indicates material stiffness, not strength. However, in column buckling, E is crucial for determining buckling load, albeit not directly indicating the material's strength. While it doesn't predict strength beyond its elastic limit, E is essential for understanding material behavior up to that point. Thank you so much for the Video it is very insightful and thank you for the promotion as well really Fantastic work.

Honestly, I feel very grateful to be able to see this videos. I just want to remind you that, whenever you feel down, please remind yourself that you helped thousands of students understand the physics behind the theoretical stuff! You are awesome!

[@satyrisque]

As a civil engineer, I've been looking for a really in-depth engineering channel on KZbin for many years, but have always been disappointed until now. It seems I've finally found something reputable. Thank you very much and greetings from Germany!

[@abu-bakr9604]

I wouldn’t have understood a lot of engineering subjects as i do without your videos. Keep doing what you do brother. We appreciate every single effort spent. ❤️.

[@les8489]

Just look at Timoshenko's "Theory of elastic stability"...This video, while very good, does not bring anything new and everything is covered in any half-decent engineering course.

[@abu-bakr9604]

@@les8489 its not about bringing anything new or just memorising formulas or knowing how to derive them, its about bringing out the beauty of it and making it conceptual and easy to understand. This channel does that for us.

[@kuma3509]

me too, Thank you

[@skazariants]

Agree. By watching this video one does not gain any knowledge related to the subject. To understand it you have to review course in Theory of Elasticity. Timoshenko is good, but N.Muskhelishvili book offers much rigorous approach.

[@VW.907]

Agree, as a layperson, being able to engage in any engineering conversation because of this video has improved the conversation. Thank you.

[@Renvoxan]

This is pure gold - 15 minutes, free and with way more digestable information that during part of the course of Mechanics of Solids nearly a decade ago, for which I unfortunately paid a fortune!

[@gabrielleheinrichs1170]

I love your videos, thank you! It's so much more understandable than the theory in my books. My favorite thing about watching your channel is understanding the "whys" and the context of the formulas + the visual examples of what the formula means! Your videos are amazing!

[@ShaunYeoh]

I feel like I was born to benefit from these videos at the right time! I'm just about to cover this in class next month!

[@sumur2289]

Please don't stop making such videos they are really helping us out .

[@NormanGamingPH]

I wish I had access to this kind explanation and education during my college days. As a structural engineer, you explained it on a level that even a student will find it understandable and how those formulas were derived from. Thanks so much.

[@paulhawkins6771]

Another great video, thanks so much. As a practicing engineer it's always interesting to go back to fundamentals and the history of how the design and analysis techniques developed. A particularly pleasant surprise was seeing the offshore pipeline lateral buckling example in this video as that's the field I work in and didn't expect it to see it illustrated to beautifully. I'm very impressed with the attention to detail with the animation of the mode 3 buckle shape and the formation of the soil berm at the buckle crown.

[@TheEfficientEngineer]

Thanks Paul - glad someone spotted the berm!

[@topordrop2402]

In less than 15 minutes you provide more insight than my professors did across several two hour lectures. The education system needs a complete overhaul. Universities need to purchase lessons like this from creators such as yourself and Real Engineering.

[@JesusMartinez-zu3xl]

What you explained in 16 minutes took my professor like 3 days. Thank you!!

Cant find much words to explain, very descriptive, simplified, neat...... appreciate you!!!

[@BoZhaoengineering]

In Eurocode 3, EN 1993, there are classified into 4 categories according to buckling curve. In many cases, buckling and fatigue govern structural design rather than material yield strength. There is no better way to understand it than your video! Superb! I've got a lot of details on how to derive the buckling curves from their origin. Excellent video on engineering!

[@hsbnworld]

Music playing in the background immerses me in engineering depth, it seems like an imagination of depth concept. U r the king of explanation and best tutor in the world.

[@Chev29]

I wish I had these videos as my engineering courses So much more interesting and better explained than the books 😅

[@markspc1]

Great video about buckling. Euler was a genius, buckling was a tinny amount of his work but with great effect. Been able to predict buckling failure can save work, money and mostly save lives. Sadly most scientist that mention Euler never mention his development of the buckling equation. In my career as a structural analyst I always dealt with buckling. A thin-walled open cross-section (11:34) beam, or column, can also fail at the flanges and at the center member. In aircraft structural analysis it is known as "crippling". Crippling can occur in longitudinal member between frames. Also another way that a slim member can fail in buckling is called "longitudinal buckling". It can be loaded in a concentrated moment at the ends or as a distributed load as in floor beam.

[@smurface549]

Concise and easy to follow. That's another quality video worth to watch. I especially love how you pronounce Euler the right way :-) Something that's probably not very intuitive: A pipe can even buckle when under tension while supporting a compressive load. We did experiments at the university showing that, but I kinda forgot the exact reason for it.

So if I wanted to find the force needed to a crush an aluminium can for example against a fixed surface, would the Euler's formula presented at 3:06 be useful to find the buckling force? and using le as 2L in the formula
