Jeff, this is an incredibly well taught lesson. Thanks for helping me iron out some hang ups I had! “Multiply by two to get in, divide by two to get out”. THAT is the mental picture I needed. Thanks! Nice verse at the end too buddy. -Destin
Can you clone yourself and teach at more universities? You’re what academia needs. Thank you for not gatekeeping complex subjects and encouraging not only your own students but students everywhere.
His country accent makes me feel a lot more accessible and authentic. In addition to that, this is a very thorough and simple distillation of an otherwise complex topic. I really like it!
Took this man less than 30 minutes to explain something that my university failed to teach in a whole week. Thank you for supporting my passion in engineering!
Was thinking the same thing. I completed my degree 10 years ago, just needed a recap. 30 minutes seems long but what he managed to explain in that time would normally take a few 90 minute lectures.
Two years have passed since this video, I can confirm that Jeff Hanson's videos are still supporting students all over the world. This video is a blessing. And to top it off, you are providing all of this for free on TH-cam. God bless you sir!
Jeff you were, are, and will always be the greatest professor of all time. Statics, Dynamics, and now Mechanic of materials. THANKS FOR ALL THE VIDEOS, BOSS!
The charisma here makes learning material so much more interesting. No matter how interested people are in a subject, it's so much harder to learn when the lectures are dry and boring. I always come back here when I'm confused becuase the energy really helps make the information way more approachable.
Dude!!! Thank you! I have Masters in Mechanical and Biomedical Engineering and my wife is Civil. Needed to calculate shear forces across cellular membranes. My wife said easy and used Mohr's circle and did it in like seconds! I went the long way around and it took 7 minutes. Just found your lecture to help me nail this down. Thank you man!
Dear Mr. Hanson, thank you so much for your commitment to these lectures! Many of them allowed me to understand what I couldn't from my university course. I wish all the teachers of scientific studies were using your methods and approach!
Got 7/7 on the final exam question for Morh’s circle watched this on the morning of the final exam. I missed the one day we covered it in class. Managed to get an A (4.0) thanks to you, no doubt.
the way he said “a radius” at 14:23 😂😂😂 I LOVE THIS VIDEO !!! thank you so much this helped me TONS i shared with everyone in my class, the book way overcomplicates this
Awesome. You just took me back 30 years. I have a current project that seems very complex but can be easily solved using the circle, a scratch pad, some simple trig, and time. 👍
I know these videos are a few years old but every one I have watched has been majorly helpful. I've got a hoarded collection of them in case I ever need to reflect on my lessons 💙
Jeff, this is an incredibly well taught lesson. Thanks for helping me iron out some hang ups I had! “Multiply by two to get in, divide by two to get out”. THAT is the mental picture I needed. Thanks! Nice verse at the end too buddy. -Caleb
Love the enthusiasm in the video! This 28 minute video helped me understand something my professor tried explaining for an hour and a half. Thank You so much!!
Thanks for doing this video Dr. Hanson! I’m beginning my studies for the FE Exam and I’ll admit that Mohr’s Circle used to seem like alchemy circles to me until I saw this video. Your explanations and clarity helped me significantly in understanding how this works!
Absolute legend thank you! Didn't understand this when my lecturer showed it. So glad I stumbled across you. Get it now and will be using other videos in the future!
These videos are a life saver! My prof's explanations are all way too theoretical and dont make a lick of sense, thank you so much for making these available!
Your channel is great. TH-cam videos are the only reason I'm going to actually get my degree. Y'all teach a hell of a lot better than the people that actually get my tuition money lol.
You use a very clever way of explaining concepts that are most of the time incomprehensible. Captivatingly wonderful! Those who know, act. Those who understand, teach. ARISTOTLE
"... How far do i have to go to get over to there... a radius". Can't help but laugh. Thanks for the lesson! I usually look for videos when im frustrated with my professors' notes and i can't help but lighten up while watching this
I have no clue how youtube guesses that I’m following this course, this is such a random and specific course which I’m only following since 2 weeks ago
A prismatic concrete column of mass density ρ supports its own weight, as shown in the figure. (Assume that the solid is subjected to a uniform gravitational body force of magnitude g per unit mass). Suppose that the concrete contains a large number of randomly oriented microcracks. A crack which lies at an angle θ to the horizontal will propagate if |Tt|+μTn>τ0 where μ is the friction coefficient between the faces of the crack and τ0 is a critical shear stress that is related to the size of the microcracks and the fracture toughness of the concrete, and is therefore a material property. By assuming that μ=0.7, using Mohr's circle, find the orientation of the microcrack that is most likely to propagate. Hence, find an expression for the maximum possible height of the column.
Thank You Man, I had a good preparation overall, exceptionally this part, but couldn’t do something good for time shortage in the last day xm of Solid Mechanics. But It's u who actually helped me to learn this. Thank u again. May Almighty bless u.
Great video. One minor correction on the angle shift transformation. It's 75.74 instead of 75.47 which throws the calculations off a tad. The last 2 digits may have swapped places. Still, a better demonstration than I had in my own class, which is why I am here. Obviously!

Thanks for the comment! Huge fan and massive respect from fellow engineer! You made my day….
Big fan of both of you guys ❤
You guys should do a video together, y'all have the same curious energy
Can you clone yourself and teach at more universities? You’re what academia needs. Thank you for not gatekeeping complex subjects and encouraging not only your own students but students everywhere.
i liked your opinion. may god bless you. Can i get in touch with you as a friend? Drop your whataappp number plz..
His country accent makes me feel a lot more accessible and authentic. In addition to that, this is a very thorough and simple distillation of an otherwise complex topic. I really like it!
Yes
Ditto! I've applied adopted Professor Hansen in place of my Statics & SOM professor. The way he covers topics of just so straightforward and clear!
Nice content

Another awesome teacher is Professor Leonard.
Thank you for uploading this, just learned it last week. This video explained it 10X better than my professor under 50 minutes🤦🏽♂️

Dr. Hanson is literally the reason I passed statics, dynamics and mech of materials.
Taking my finals for engineering today and I graduate on Friday. Just stopping by for a quick refresher. Thanks for all the help, Jeff!
I could not imagine going through solids without your classes!! Thanks prof

It is just orgasmic how crystal clear you make it all when you add the coordinate transformation with x and y face very explicit .

Instead of freaking out about this last unit the day before the final, I actually understand it and it's the coolest thing ever. Thank you :)
Awesome. You just took me back 30 years. I have a current project that seems very complex but can be easily solved using the circle, a scratch pad, some simple trig, and time. 👍
I just wanted to say your videos have saved me!!!! You are getting me through finals, and I appreciate your videos so much!
I have learned more from this video than I have from my professor in weeks. Thank you. Please continue recording and teaching. you are amazing at it.
I know these videos are a few years old but every one I have watched has been majorly helpful. I've got a hoarded collection of them in case I ever need to reflect on my lessons 💙

I can't even explain how simple this guy makes it. My engineering teacher was teaching us this I was confused but after this I get it
Love the enthusiasm in the video! This 28 minute video helped me understand something my professor tried explaining for an hour and a half. Thank You so much!!
Yo Mr. Hanson i got a 100 on my strength of materials final, couldn’t have done it without you 😎👍
This man has saved my academic career. I owe you my life, sir
this guy has single handedly saved thousands of engineering students...
I was in hot water until I found this video, saved my life, thank you

nobody taught this topic so well as you did!. this helped alot.
We need more professors like you! I wish you were my engineering professor!
You make our lives easier by these lessons, god bless you. Best professor i've ever seen.
Your are the best solid mechanics teacher I have seen. Thank you Mr. Jeff Sir
You are the man!!!!! half a video in and you are my fav YT prof. (I have seen like thousands lol)
Youre a HERO here at San Diego State University!
Hey I go there as well. Go Aztecs!
Hello how are you 💝💝💝💝💝💝💝
Best professor out there! My professor should be ashamed!
Absolute legend thank you! Didn't understand this when my lecturer showed it. So glad I stumbled across you. Get it now and will be using other videos in the future!
I'd like to thank you for these wonderful lectures because, thanks to you, I will be getting an AA this semester!
My new favourite professor!!! A true life saver!
Thank god for TH-cam, because this exact video just saved me a lot of time going through my old textbooks
omg the best lecturer ever , first time i understand all what a lecturer say , thank you

Can't thank you enough for how clear your explanations are
These videos are a life saver! My prof's explanations are all way too theoretical and dont make a lick of sense, thank you so much for making these available!
Very nice! I can't understand these subjects any better than I do with watching your videos.
thank you for the explanations Mr. Hanson, definitely helpful, what u taught in this video will last for eternity, wishing you well, and God Bless
Jeff Hanson is a talented teacher. Recommend his videos to students.

Mr Jeff, there was a slight error you made with regards to angle phi on your Mohr's Circle. You wrote down phi= 29.47 degrees instead of 29.74 degrees
I'm actually conf about that, he got 75.47 from somewhere
@@tturi2 same
Sir literally i was feeling depressed and i started this topic with your video ,really enjoyed this video i wish i had teachers like you
Boy do I wish I had this video available 60 years ago when I was taking Strength of Materials at UCLA !!!
go slow on the thing nobody needs and go super speed on the hard thing and people in here still gives compliment.
Thx for youtube algorithm, bringing me to your channel before the final exam, and help me get an A grade in Structural course. Thank you!!!

Now I make that sound in my mind everytime I rotate anything so thanks Dr. Hanson.
helped me more in 20 minutes than my professor did all semester
"... How far do i have to go to get over to there... a radius". Can't help but laugh. Thanks for the lesson! I usually look for videos when im frustrated with my professors' notes and i can't help but lighten up while watching this
You're the goat. Absolutely saved me on my homework
I mean what a mentor ...... much love from Egypt❤❤
I have no clue how youtube guesses that I’m following this course, this is such a random and specific course which I’m only following since 2 weeks ago
Taking solid right now, and we talked about you in class, thanks for your videos
Mohr circle examples
th-cam.com/video/eDCcN1Yievk/w-d-xo.html
Dr Hanson, can you make some video regarding to the plastic analysis of beam? Thanks
To be honest, Mohr Circle is wayy more complicated then plug & chug into the equations...
If you have a formula sheet*
you jus saved my degree!!!!! The GOAT
thank you Jeff! I am forever grateful for your goldmine of videos
Welcome back Professor Hanson!! Great pleasure to see you back.
You are the best Jeff! Thanks for everything, keep it going and I wish you nothing but the best, greetings from Malta
God bless you sir, this has made it so much easier to understand!

i am not understanding how you got the 75.47 for the angle when u rotated it. please someone explain
this is really from the best videos or channel I ever watched
Thank You Man, I had a good preparation overall, exceptionally this part, but couldn’t do something good for time shortage in the last day xm of Solid Mechanics. But It's u who actually helped me to learn this. Thank u again. May Almighty bless u.
Not one thumbs down cause you're AWESOME PROF
That circle drawing technique is interesting.
The verse is my favorite part😅😁that kind of encouragement is very much needed especially in the world of learning....thank you💯
Please make more content for dynamics, every class you teach I get an A in but the other ones not so much, you are amazing Jeff
I wish one day be your student. I am 46 years old still in school and enjoying your lecture!

Can we find the radius?
Jeff: Well, heck yeah!
Got me rolling while learning 🤣😭
SIR STOP!!!
YOU ARE MAKING IT TOO SIMPLE, ITS TOO EASY TO UNDERSTAND OMG!!!
I just learned this today and the professor made it so difficult it’s ridiculous
thank you Dr.Hanson❤❤, you've helped me and my colleague so much that we can't thank you enough!!! we love you
Great video. One minor correction on the angle shift transformation. It's 75.74 instead of 75.47 which throws the calculations off a tad. The last 2 digits may have swapped places. Still, a better demonstration than I had in my own class, which is why I am here. Obviously!
I was confused for 5 min for this part😂
Part E mannn 😂😂😂 ... I love this teacher ☺️❤️
Thanks alot Jeff.... Regards from Uganda 👐
I wish I could divert my tuition straight to you. My university hasn't earned a dime.
Your a lifesaver, I love your teaching style
Hoping to get myself saved in my Strength of Materials Examination on Wednesday...
my college calls this class strength of materials. thank you for this video and many many others!

This video is helpful for Geotechnical Engineering thank you!
Agreed!!!
Great lecture! Please discuss 'Theories of failures' with applications
Thanks in advance
thank you
Thanks my teatcher sucked, you helped me out alot
