Understanding Stress Transformation and Mohr's Circle 

Thanks for watching! Mohr's circle really is a key topic in strength of materials. Here are a few useful links: ➡Read the Mohr's Circle article on the Efficient Engineer website: efficientengineer.com/mohrs-circle/ ➡Get access to one-page summary sheets for key engineering topics: efficientengineer.com/summary/

Only a engineer can understand how much effort he had to put to make this type of quality videos....salute to him.

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 RU-vid and found this video. It was so freaking simple. I feel like a fraud!! Thank you soothing voice guy!

This channel is the 3blue1brown for mechanical engineering. Love it!

I learned more in a 7:00 video than I did in a 3 hour lecture. Thank you

Solid video! Thanks for making it.

God I love mechanical engineering so much! Seeing how abstract theoretical concepts can be applied to tackle day to day problems is amazing to see!

One of the greatest explanation I have heard for this topic ,waiting for more videos.great work sir.

Holy cow. Simply phenomenal. Somebody donate to this guy to fund more videos!!!

Quality videos like this should be made and sponsored by the government for all topics of engineering.

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 🙏🏻🙏🏻🙏🏻

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

So well explained. Honestly man, you're doing gods work.

The perfect explanation for a chemical engineer who has no clue about mechanical stuff. Great job! Thanks a lot!

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.

Why is this video not more popular?? Its a perfect explanation

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

My mind just blew out..This might be the best possible explanation provided in the world about that concept.

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!

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!

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!

This channel is gold Every university should use animations like that to explain these concepts

Finally, I understand Mohr's circles. Somehow, I passed machine design without understanding the concept :) The video was great!

I always come back to this video when I need to refresh my memory on some of these concepts!

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!

Dude, you explain everything so easily, sure the visuals help but you also keep it short and include examples. Thanks a bunch

I could visualise more how much deep and detailed work was put into this video. Thank you for your dedication and patience.

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!!

Excellent video, as always. I wasn't aware that Mohr's circle existed for 3D stresses as well. :)

This channel is making a huge part of my degree. Thanks a lot for epic content

Thank you for such an amazing video! This has explained the topic better than my college lectures!

Awesome video. You explained in 7 minutes what my professor couldn't in 30.

I keep falling asleep during my night classes. You guys are lifesavers.

I cannot strees enough the educational value these videos have.

Sir you are great in teaching something with most related practical application ,always be yours fan

Oh my god...This is the first time i actually understood it without making a mess..Thank you

Now I'm in luv with Mechanics of materials. ❤

one of the best videos ever. Thanks a ton @The Efficient Engineer.

One of the most intuitive videos I have seen on this topic. Hats off.

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.

You explained it in 7 mins which my ketçaplı patso professor couldn't do in 3 hours. 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.

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!

Two weeks or 4/5 hrs of lecture is in this video. Thanks a lot for making mohrs circle crystal clear.

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.

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.

this is one of those classic youtube engineering vids i keep returning too, even just for ol time's sake

Thanks!! It was only your video which clarified my confusion between 2d and 3d mohr circle.

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.

Really help me alot. I was having trouble understanding mohrs circle... But thanks to you I now have a better understanding of the topic.

the way you simplify the things is amazing, keep it up cuz honestly, I am in love with your work

This was great! Statics & Mechanics of Materials 2 is really tough, so thanks for having a video on this very specific topic

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

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

we mechanical engineers really need you

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.

Thank you so much for these videos!! they have helped me out so much in engineering school

A fine explanation with necessary details

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!!

I come to this channel to have piece of mind. thanks for your effort.

This video is amazing, you explained very well, thank you!

Quite literally learned more in 2 minutes than I have in 4 hours of lectures, thank you.

Best channel for Civil Engineering

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.

Your lectures are simply amazing! Thank you for your excellent work.

Salute to you sir! These amazing animation make things easy understanding. Very helpful for mechanical engineering students like us!

you are one of the best friends that a civil engineering student would have thank you from my heart's centroid

.... in 7 minutes... you destroyed what was literally hours of lectures to me Don't stay in school kids, watch this instead Fantastic Video

You are making me slowly like mechatronics engineering. As a software developer, I always regretted going into eng school and wasting my time learning mecheng concepts. But thanks to your videos, learning it is getting easier and fun, thank you.

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... :/

Hope this channel makes it big Mechanics never gets its share of love on youtube There are very few channels like this Please keep the videos coming I will continue to support to the best of my ability by liking and sharing the videos

Simple elegant, simply superb and clear explanation

Two-minute silence to all those who didn't understand engineering mechanics this way...!!!, epic bro... loved the subject even more...!!!!

You make one of the best videos on the internet explaining abstract mechanical concepts. Please upload more such videos. Sincerely.... A thankful engineer

The most perfect explanation I've ever seen 👏👏

I wish I had this 4 years ago. It's good to go back and review though. Thanks for the great video!

I've never subscribed that fast in my life. Gold content!

I needed this video 24 years ago when I was taking Strength of Materials course...

If only my uni lecturer explained this so well in class, i might have passed geotechs :D

This is a tremendeusly amount of work and knowledge this guy has put in this video. You are awsome bro

Wow this is really well made. If only my lecturers were this good at explaining it.

Always my favorite youtuber when I want SOM videos

Should've known this channel before taking solid mechanics class

This was way better than any professor taught Mohrs circle.

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.

This channel has made me understand concepts very easily. Thank you for making such quality videos.

That was the easiest and simpliest explanation of the Mohrs Circle idea. Thank you, great stuff

best educational video i've ever listened to.

I know this comment is a bit late, considering the video was published a long time ago, but the explanation was pure gold!

very good explanation to something I have barely understood before

Thanks, I am grateful of this great video.🙌

im a simple engineer.i see a efficient engineering video, i like.

When I leave my Structural Mechanics exam today, I will have a beer in the name of "The Efficient Engineer" You're doing God's work.

This is really good, deserves more attention.

I always get to know new things through your videos, please post more videos on material properties, strengths, stresses etc too.

Soooooo gooood！Much better than my professor. It is brief and clear!

May be this 1st video on understanding ever better than any yet..

Thank you. Have exam today and this really helps! 🥺

Unbelievable.... Great Explanations.... This cleared our Concept.

It is One of the confusing topic i have gone so far , but the way you teaches ,it's very appreciable ❤️ .thank u for understanding the concepts in a simple and quality way❤
