Understanding Stress Transformation and Mohr's Circle
Ғылым және технология
In this video, we're going to take a look at stress transformation and Mohr’s circle.
Stress transformation is a way of determining the normal and shear stress components acting at a specific location within a body, as we rotate the coordinate system we are using to observe the stresses.
And Mohr's circle is a very simple but powerful technique we can use to represent stress transformation graphically.
We can use Mohr's circle to easily determine the principal stresses, the angle of rotation to the principal planes, and the maximum shear stress.
The principal stresses occur where the stress element is oriented such that the shear stresses are zero. For plane stress conditions there are two principal stresses, which are the maximum and minimum normal stresses.

I have a Master's degree in Mechanical Engineering. For some reason, I never understood Mohr's Circle when my professor taught it around 2010. It's been bugging the hell out of me. So I looked on KZread and found this video. It was so freaking simple. I feel like a fraud!! Thank you soothing voice guy!

Hey I'm currently in my fourth year of mechanical engineering (bachelor's, obviously), and I have never learned this thing. Is this a master's degree subject or something?

Abi Rizky Hey man, no. You will learn Mohr’s circle when you take courses like Mechanics of Solids, Analysis of Structures, Concrete Design, or any course that teaches compressive forces on beams, rods and other rigid bodies. I don’t think you encounter those in graduate school. Good Luck!
Solid video! Thanks for making it.

It's nice to understand different kinds of theories that composes the matter and the way in what we use the math for. sometimes is really hard to see that some materials have different theories over what they function or fail.

This is one of those engineering concepts that transcends mechanical. Civil, Structural, Geotechnical, and Aerospace also use all of these concepts.

I studied about mohr’s circle in my very first semester. Now i am in my fifth semester and doing some analysis of structure in civil engineering. I proceed to recap what i have learnt, then i found this amazing explanation with a little bit intuitive of what is stress transformation really is. Many thanks for the uploader 🙏🏻🙏🏻🙏🏻

Quality videos like this should be made and sponsored by the government for all topics of engineering.
Ducking Thank You !!!!!!! when you said that an application for when we will need to know the stresses at angle is knowing the normal stresses across a welded part, was an amazing example.
Your videos are awesome, as a civil engineering students I can say that this helps a lot to consolidate knowledge that are a little bit difficult to imagine by only reading books! Thanks for the effort of making this material
Apart from the fact that the process of understanding Mohr's cirlces has given my stupid brain permanent damage, got me thinking extensively about my career choices & made me question some of my life's core values...your video was pretty helpful. Thank you!
The perfect explanation for a chemical engineer who has no clue about mechanical stuff. Great job! Thanks a lot!
Saying thank you isnt enough , even if i fail this exam ill leave happy knowing i can go home and review with your videos and learn quickly and effectively
So well explained. Honestly man, you're doing gods work.
Why is this video not more popular?? Its a perfect explanation
I could visualise more how much deep and detailed work was put into this video. Thank you for your dedication and patience.
My mind just blew out..This might be the best possible explanation provided in the world about that concept.
With a masters degree in engineering I always felt this concept difficult to understand by reading theories from textbooks and trying to analyze 2-D drawings. Thank you so much for making this clear. Subscribed!
I'm an undergraduate in biomedical engineering with a focus in electrical engineering and medical devices, but a great hobby of mine is exploring the fields of mechanical and aerospace engineering. These videos are great and help me so much in the more mechanical-engineering based courses I'm taking, and it's great to see how these concepts extend to real-life structural applications, whether it's on a bridge, building, aircraft, or inside the human body. Neat!
Finally, I understand Mohr's circles. Somehow, I passed machine design without understanding the concept :) The video was great!
Take a bow sir!!!!! I am certain that not a single tutor video will be as accurate+explanatory+doubts clearing++short as this on youtube. plenty of likes and well wishes to you sir for such great videos.
no other video has explained the way you have like step by step incrementally introducing the concept of various type of stresses. Just loved it. Other videos are so mechanical.
Oh my god...This is the first time i actually understood it without making a mess..Thank you
Thank you a billion times!! I don't understand why my professor at my uni still teaches these concepts traditionally. What us students need is exactly THIS!!
This made studying for my Def Bods final 500000x easier. You explained it so clearly and easily, way better than my professor's notes. Thank you so much!!
Dude, you explain everything so easily, sure the visuals help but you also keep it short and include examples. Thanks a bunch
One of the most intuitive videos I have seen on this topic. Hats off.
This was great! Statics & Mechanics of Materials 2 is really tough, so thanks for having a video on this very specific topic
Thank you so much for this video! Im currently studying for strutural geology exam where we deal with material properities and Mohrs cyrcle a lot. This video has made a lot of concepts clear for me!
I wish I had this 4 years ago. It's good to go back and review though. Thanks for the great video!
This channel is gold Every university should use animations like that to explain these concepts

I'm not an engineering student, only a geology student. Yet, we still have to learn these topics (Stress, Mohr's Circle, etc) in determining rock mechanics and geotech. My midterm exam is tomorrow, so thank you for helping me.
This is a tremendeusly amount of work and knowledge this guy has put in this video. You are awsome bro
one of the best videos ever. Thanks a ton @The Efficient Engineer.
You explained it in 7 mins which my ketçaplı patso professor couldn't do in 3 hours. Thank you so much
I’ve watched other videos on stress transformation but none of them helped you visualize it with graphics. I just wasn’t able to understand it until this video. Thank you so much!
Wow- I agree with the comments. The visual representation of this topic which confused me at University made it simple. Thanks a lot.
Excellent video, as always. I wasn't aware that Mohr's circle existed for 3D stresses as well. :)

I'm so happy I found this channel. Failed solid mechanics, but now I feel like I have a chance to gun for a *much* better grade the second time around.
Oh Gosh this channel is just SO GOOD! And that's an understatement. Thank you so much for this video and all of your videos. They are so helpful to understand the concepts WHICH IS THE MOST IMPORTANT THING. I was just doing some higher level stuff and I was tripping because I was a bit rusty, but this video HELPED SO MUCH. I can't thank you enough @The Efficient Engineer.
If not the best, atleast the best video for me to understand the Mohr's circle and the principal stress, strain. I am so obsessed with this guy.
my bro you should be given 1M $ for every video you make you saved my life in Mechanics of materials and now you are saving it again in fluid mechanics all respect for this herooo
Now I'm in luv with Mechanics of materials. ❤
the way you simplify the things is amazing, keep it up cuz honestly, I am in love with your work

Haven't been to a single solid mechanics class besides syllabus day. Just watch these videos the night before tests and am averaging a 95. You are the goat
Two weeks or 4/5 hrs of lecture is in this video. Thanks a lot for making mohrs circle crystal clear.
your videos are so informative! thank you for taking the time to make them, they're incredibly helpful!
Really effective and accurate illustrations. Kudos! Please consider making a short video about Mohr's circles for strains and for 3D stress states.
A fine explanation with necessary details

This lecture in schools is simply 6-8 hrs long and not even as close to clarity as this video is... This is the best on mechanics I have seen so far... keep up the good work Efficient Engineer... I wish I had youtube when I was in school and a channel like this 13 years ago... :/
This video saved me hours of studying for the PE exam and blew my mind at the same time. Mohr's circle is awesome, and this video explains it well.
