I created another Mohr's circle explanation video, since the the volume of the first video was so low. The new version is better, faster, stronger? Well, definitely louder.
I really wish we had videos like this when I was in college. Having these concepts explained in different ways by different people would have made it a lot easier to understand.
dude...dude...thank you so much! for some reason, Mohr's Circle seemed so abstract to me but you were able to demystify it and clarify so many things for me.
The convention you show (up/right is positive, down/left is negative), is contrary to the method I learned. The method I was taught is to isolate the shear stress and consider it as if it was the only one acting on the square. If it would move the square clockwise, it is positive, if it would move the square counter-clockwise, it is negative. I believe you account for this discrepancy by flipping the direction of the tau-axis so that positive is down. If you use the method I described, you can keep positive tau oriented upwards, which is more intuitive. I also think it is just a simpler way to determine the sign of the stress. If people are having trouble with the method you show in the video, hopefully this can help.
I know this is an old video but around 3:00 minutes: To know "Shear Stress" sign, you'd have to count Shear is positive if it's CCW. Shear is negative if it's CW.
structurefree ohh yeahhh😂😂😂 I almost forgot I was in a digital class and not a physical one. Thanks for your help. I’m a Mining & Process Engineering student and I have to ace my Rock Mechanics module and you’ve been of great help 🙌🏽❤️
from how you explain the sign of tau xy and tau yx at around 2:30 , i feel you will have a problem representing face-y on Mohr's circle as tau xy = -tau yx. Correct me if i am wrong.
+fooser No, tau xy = tau yx. This is a basic concept in principals of plane stress. You can derive it easily. If you wanna look at it with some logic, both should be equal since the cube shouldn't rotate in equilibrium. Look at the positive directions of tau xy and yx. They are counter-rotational.
does that mean if trow was positive upwards, a clockwise rotation to the principle axis on the mohrs circle would be an anticlockwise rotation on the element to the principle axis? n thanks for the videos
Do you have derivation for stress transformation equations ? There is one book by James and Barry, they relate the angle of principal stresses and angle of maxium shear stress as theta_s=theta_p - 45 degree . I however tried derived myself and get theta_s=theta_p + 45 degree
Most People are watching this because they need to complete college work. I'm just watching this because it's fun I've taken an interest in engineering and biology And i'm only eighteen
Dude what about shear stress on y axis,according to ur convention the sign of that would be negative but by ur assumption of positive and negative shear stress it must be positive..
1:19 "... problem starts by giving you a state of stress."
Reinis Trasūns accurate

thank you so much..... you have been so helpful ...
Salwa N no problem. I'm glad they are useful.
I wish that you do more videos on buildings structural design ...and by the way it is so energetic being loud ..
do you mean steel design and reinforced concrete design?
what software do you use to make these videos?

Please Please keep the work. I do not know if you're a college teacher but you have a talent. I wish this channel was here for forever.
I can't thank you enough structurefree. You've made this video for the sake of simplicity. God bless you!!!
dude...dude...thank you so much! for some reason, Mohr's Circle seemed so abstract to me but you were able to demystify it and clarify so many things for me.
dude i freaking love youuuu ! thank you

Thank you very much... I encountered the same problem. Thank you for your information.
You are incredible and would give you 5 stars for your teaching method.
Excellent Stuff on this Channel.
i can't understand, why that shear Stress is taken as positive in downwards direction can you explain it please with an example
Jesus this video is amazing
Yes!!! Can I get a witness!?!
best youtube channel ever
Your explanation is amazing!! Thank you so much!!!
I know this is an old video but around 3:00 minutes:
To know "Shear Stress" sign, you'd have to count
Shear is positive if it's CCW.
Shear is negative if it's CW.
Oh my days! How can someone explain this to me in less than 7mins when my lecturer took a whole 2hrs🧐 thank Goodness for you
Editing
structurefree ohh yeahhh😂😂😂 I almost forgot I was in a digital class and not a physical one. Thanks for your help. I’m a Mining & Process Engineering student and I have to ace my Rock Mechanics module and you’ve been of great help 🙌🏽❤️
Good luck with your final! Mechanics works everywhere...some might say it rocks! 😬
structurefree 😂😂😂 good one!!
Your videos are so clear and easy to understand. Thank you!!
th-cam.com/video/eDCcN1Yievk/w-d-xo.html
sangat membantu. Terimakasih banyak.. good job!!..
Thank you Sir. You are better than my college teacher. I understand a lot more from you.
YOIU ARE REALLY HELPFULL YOUR VIDEOS ARE THE REASON IM GETTING MY DEGREE
Finally understood shear tensile convention! Thanks!
This is soo Good! Video presentation, explanation and clarity. Thanks, for getting straight to the points!

I always learn ALOT from your videos. Thank you soooo much!!
Thank you. for this video i was able to answer my semester finals.
dude your voice just made me so amped for strengths XD thanks for the video
does that mean if trow was positive upwards, a clockwise rotation to the principle axis on the mohrs circle would be an anticlockwise rotation on the element to the principle axis?
n thanks for the videos
*POSITIVE!* 😂 I loved the way he pronounced it. Great video! Helped a lot.
pronunciation 🤣🤣🤣🤣
sir, we use Mohr circle for measure the normal and shear stress,is it true?
.... 2:34 and beyond : A fest of "Pphaaaaaaazitive"s
what program do you use to draw
Do you have derivation for stress transformation equations ? There is one book by James and Barry, they relate the angle of principal stresses and angle of maxium shear stress as theta_s=theta_p - 45 degree . I however tried derived myself and get theta_s=theta_p + 45 degree
Wow you are amazing! I should have watched these videos long time ago! !
URGENT! why is the tau xy is below of the x axis ,isnt that makes it negative ?
For people who are still wondering, it is just a sign convection. Just remember that.
much love structurefree, god knows I hate reading my textbook. Thank you so much!!
Where were you when I needed you last year
hello, i am still confused about the sign of the shear stress. My final is in two days, Thank you in advance.
brother, I want your help
I want a lot of things....brother! But mostly I just wanna be a baller.
@@structurefree I was waiting for your response, my question about engineering plasticity. So could you please give me your email. Thanks
I dont know how i can repay you..... YOU HAVE SAVED MY LIFE and im not even exaggerating
in the video you said that the radius = (ox +oy)^2 +(Txy)^2 ......is it not supposed to be [(ox +oy)/2]^2?
Thank you for this video it was a big help for my mechanics midterm :)

How to derive the transformation equation
this video's great and I hit the like button "BAM"!
great video! Thanks
you deserve this love from people. I will say it in arabic language أحبك
What is the phisical paln
I would be good to learn more about the stress element before using it in further explanations.
Florian R. Klein ok. thanks for your comment.
can you explain me about signals T++ T+ please?
can soils experience tension?
phasitive and phasitive makes it another phasitive.
BTW great video.
Could u make a video showing how to derive the Stress Transformation EQUATIONS? Thanks in Advance
''ur videos are awesome''
+David Galvao these are definitely on my to do list. hopefully later this year.
excellent teaching
why does no one have and example of a 3d Mohr's Circle :/
"Now's the time to find something round" - Beer can works haha
🍻
This is still so much sophisticated..... I wish u could make this a Lil more demonstrating
Aquib Ateeque it might help to watch the example problem video.
thnx fa ur advice sir.........i certainly will
You are the guy! I learned a lot! Thank you!! STRUCTURE FREE LEARNING!!!
ball so hard, mofo's wanna find me.
Most People are watching this because they need to complete college work. I'm just watching this because it's fun I've taken an interest in engineering and biology And i'm only eighteen
Why you drew positive axis downward . why cant u use it as upward 😊
Dude what about shear stress on y axis,according to ur convention the sign of that would be negative but by ur assumption of positive and negative shear stress it must be positive..
And it makes sense.
Thankyou!
In other videos, tension sigma is negative. I'm confused right now. -.-
Hmmm, where? Maybe in soils?
thaknk you sir,i really appreciate this explain
thank you sir, but can you make a variety of languages?
told me to buy a compass in 2nd grade, finally using it 12 years later...
It's like finding money in your pockets.
Why couldn’t my professors make it this simple
THANK YOU!!!!!!!!!!!! SO MUCH
Thank you very much
Many thanks!!!!!!!!!!!!!!!!!!!!
you are awesome thx for the vid :)
After watching this video, you can understand how it works in 3D using this app: play.google.com/store/apps/details?id=mechanics3d.app
Thanks
thanks, this helps :)
Thanks bro 💙
★★★★★ excelente sevicio
cool!
Thank you
i love you!
youre not consistent with sigma(x') and sigma(x). Its super confusing
Thanks yo
ain't no thang.
I love you
If you are not a genius then you live in Pluto ...
I need values bruh
Play at x2 speed :DD

I’m stressing out about this topic.
