CEEN 341- Lecture 12 - Stresses in a Soil Mass and Mohr's Circle

[@theunity6680]

This is the first time i understand Mohr's Circle! Thank you so much professor!

[@DanildFlamme]

I think this is one of the best explanations on Mohr's circle I have found sofar. Both in books and online.

[@karanprem9280]

I have been watching your lectures for past few weeks and your way of teaching is remarkable. Especially your 3D figures

[@StardustSpeedman]

Your lectures are brilliant! Thank you so much!

[@kwstasvasiliadis5081]

Thank you very much for this lecture. I always found it really complicated, but you explained it perfectly. Greetings from Greece!

[@ilaragade2596]

Hello Professor, this video has been really helpful for me. I have just begun studying advanced soil mechanics with no background whatsoever in civil engineering (I'm pursuing my masters in Environmental Engineering and need to study this subject for waste treatment design. I'm a mechanical engineer). I am subscribing to your chanel so that i can turn to your videos when I'm in doubt.

[@anthonyallen9719]

This is the only video out there that makes sense, thank you so much!!!

[@msj926]

thank you so much ...your lecture is very great and making me easier to understand the concept of mohr's circle . This lecture helped me a lot in studying this chapter

[@agustinusyosef2157]

I almost cry when my teacher explain this to me. Thanks to you i can understand it now.

[@teremardiandra]

me too

100% amazing teaching.

[@jinyizhang1846]

Best lecture on Mohr's circle.

[@beab1200]

easiest lecture to understand by far. thankyou

[@2000nawabali]

Dear Sir, Franke, Ur lectures are simply awsome. Thnx a bundle

[@mayurrathod4952]

Gr8 explanation through video that could not understand via books....i thought that much complicated concept would not cover by me,but after watching your lesson i want to watch more videos like this on soil mechanics plz uplode more stuff like this..thank you so much sir.....

[@skyechapman8568]

This has helped me so much, thank you!

[@twigsfloat2773]

This was excellent! Thank you so much for posting.

[@ali.5785]

Hey man thanks a lot for the lecture it helped me a lot this might be the only video that I dropped a comment really appreciated.

[@chadhawley9230]

Top class, help so much to understand the basics!

[@muhammadhossam8557]

thank you very much for your beautiful and great explanation

[@nissarali9809]

Sir plz..... Upload more and more videos on soil machanics.... Ur lacture help us to understand the practical knowledge which we can't understand from the books.. Thank you soooooooooooooomuch sir.... May God bless you.

[@iaincrawford5472]

Another great lecture!

[@meermehran007]

As simple as it could get!

[@victorceolin7322]

Thank you so much sir!

[@sumanadasarajapaksha5081]

thank you sir, it is very easy to study your lessons. ☺

[@rezarazaghi2438]

appreciated, it's really great lecture.

[@emirokucu523]

you are the greatest

[@farasabyan45]

Can you elaborate on why the normal and shear stress acting on the plane is always located 2(theta) away by rotation about point O of the RM line? Thank you for the video!

[@stooncol619]

Thank you very much

[@bijendrasingh7604]

superb man

[@bSMith266]

this is the hardest concept for me to understand. Would be good to understand its applicability in construction practice

[@lloydwebb6200]

With the orientation for the major and minor principle stresses @31:20, are they with respect to a horizontal Cartesian axis or the inclined plane at 30 degrees? I compute the rotation to the horizontal axis sigma which is 41.5 degrees in morh's circle (20.75) in real life but then I'm stuck on what to do to get to your answer, any help will be greatly appreciated!

[@bonkoFL]

[Obviously the question was long ago, but still a good one for anyone looking at this now.] His answers are relative to horizontal. Your 20.75 deg is the amount the box would need to be rotated clockwise from its tilted starting position in order to counter the effect of shear stresses. Since the minor axis of the tilted box starts at 30deg, 30 - 20.75 = 9.25 deg relative to horizontal, while the major axis starts at 120deg, 120 - 20.75 = 99.25 deg relative to horizontal.

[@Kasra-shaah-doost]

very useful

[@dollarbulldog5492]

Thanks!

[@umarfarooq156]

How do you calculate or drive these equations at 11:40 and 12:00?

[@asimnazir3125]

You have said we can calculate sigma 1 and 3 if we know sigma x and sigma y ....but how can we get sigma x and y in a real life problem.... Whether through a field test....kindly explain

[@ingmarvdlee]

Watch lecture 10, maybe that will clear things up.

[@JamesDean.]

Thank you!

[@cengizgulmez1608]

could you please some one explain me finding pole at 30:43. there should be a geometrıc solutıon.

[@masterbitter7688]

looking for it too

[@danielluning3182]

Is it just me, but does he sound like David Duchovny from the X-Files and Californication?

[@koushikhalder2803]

Very nice :)

[@manandianupama3453]

thank you

[@kennyperez1085]

thanks a lot

[@YagamiLight69696]

The principal stresses at a point are sigma1= 250MPa and sigma 2=120 MPa (a) Determine the (i) mean stress, (ii) differential stress, and (iii) deviatoric stress. (b) Using the Mohr circle below, what are the values of the normal and shear stresses acting on two planes whose normals are inclined at: (i) 0 degrees to the sigma 1 direction? What quantity does this point represent? Based on your calculations, do these results make sense with the orientation of the plane relative to sigma1? Explain. (ii) 45 degrees to the sigma1 direction? What quantity does sigma n at this point represent? (c) Using the Mohr circle below, what are the values of the normal and shear stresses acting on two planes with normals inclined at: (i) 60 degrees to sigma1 direction? (ii) 90 degrees to sigma1 direction? What quantity does this point represent? Based on your calculations, do these results make sense with the orientation of the plane relative to sigma1? Explain.

[@YagamiLight69696]

Can any one help me with this

[@rubenaguilar1360]

If angels exist you are certainly one of them

[@lyrolrethbarker5148]

can u provide me link to download your pdf sir?anyone have ? can u share with me? too I need to do with my presentation

ϴ = 99 ? 32:25

[@bhasouza]

Should be 81 degrees (180 - 9 - 90) ? I also got confused.
