Unable to get answer for hollow one

Thank you sir for uploading these lectures..

Thanks for the informative video. Can you explain why the shear at side are not zero, even though there is no shearing plane on it, just like top and bottom. In other words, what is special for top/bottom to have zero shear but for sides have shear?

just amazing you saved me i am having my mechanics of materials paper tomorrow

Which book do you have used?

thankyou sir

This was very very helpful.. thank u very much.

SFD has a mistake. SFD at load point P should be +0.043.

I'm student of Civil Engineering in Bangladesh, Prof. Jay's lectures helped me lot & still helping! Thank you so much, Sir! Accept my humble gratitude.

These lectures are a diamond mine!

sir 8:02 shear stress is negative right ? then by substution in shear formulae it should yield value of 43.8 MPa right ?

Sir why le=4m in the 2-2 section?

Can't express in words your great teaching

Thanks sir for clearing the concepts

Sir, where can I find the introduction chapters. Like Topic #1.1? Sir your videos are really very helpful

Dear professor, apart from the logic we know for those moments at the ends, lets have a look into those mathematical relations. As of solving the moments between A and B i got 6.75 kNm. If the moment at A and moment at B are tends to be zero how am i able to get a value above zero. May be i am confused or wrong. Please let me clear about this topic. Thank you 😊

Sir thank you very much for such amazing lectures

For the equations for "Total deflections @ B" how did you get 41 on the numerator for final deflection of B?

I have a little bit confussion about the shareflow direction about I section and C section Once video you showed for C section @ web share flow is opposite to external force And another I section where it seems parallel

Why is there no shear in pure bending...will the 'layers' of beam not tend to 'slide' with respect to each other in pure bending?

Why is there no shear in pure bending...will the 'layers' of beam not 'slide' with respect to each other in pure bending? Also, why is that not the case in, say, a cantilever beam with point load at the end?

Thanks for clearing up my concept. I know that you didn't cover the torsion for the non-circular section, but I will be glad if you do, sir.

thank you sir

i get the I=184.........

18:54 sir where can we find the notes

Thank you sir a lot. For the first time i can feel that how forces act in real. Hats of to you sir ❤❤. Wish i had seen your lectures earlier.

@ prof Jay Ghosh , Sir in flange we have complementary shear arise due to resisting shear force in the same way in web also we have resisting Shear force in upward direction only Why your using same direction (downward in web ) as that of loading V ? . Sir kindly ans it I’m very much confuse with Shear direction in thin section especially in Web shear flow direction .

Sir please teach more topics on this stability/buckling part of beams/columns/frames Like snap theough buckling , post bucling , bucking of beam -colums , static , dyanamic and energy methods of stability

Great video 👌

That twisting experiment... Based on true story! literally got me😄

THANKS YOU VERY MUCH!!

best teacher on youtube!

Isn't the final fig for max shear wrong in terms of the direction of sigma x as it should be compressive 35Mpa?

Thank you Prof.

Your insights makes everything so much more clear. Thanks for uploading these, and spreading knowledge.

For no Torsion the plane of bending should pass through a)neutral axis of the section b)shear centre of section c)be parallel to one of the principle axis ?

This is amazing teaching. Thanks a lot! I've been using these without understanding where they came from.

You're absolutely amazing! Clear concise explanations. Wish my professors were half as good as you are.

Sir literally had goosebumps. Felt like crying after watching you explain it so calmly. Was about to give up but suddenly came across your video. This is by far the hardest topic of this course. Thank you again. May God bless you.

Amazing video with clear explainations and images..i still have doubt about the direction of flow at web..at flange the concept was shown..if same concept is used at web then the direction would be opposite of what was shown here..

thank you!!!!

That was actually very interesting...Thank You. I've been a P.Eng. for over 25 years and I love how you logically presented shear flow. Thank you for sharing. P.S. Your casual comment about deriving equations for thin walled sections requires that we measure to the centrelines is KEY and allowed me to derive the shear in the web. Thank you again for this.

Will you make videos on structural analysis and Design?

Very perspicuous. Thank you sir

Well explained.. Thank you.

Sir, your explination cleared my complete basic understanding of this concept ! Thank you ! LOVE FROM JADAVPUR UNIVERSITY SIR 🤗💝

Sir does pure shear stress Planes only exist on maximum shear stress Planes??

Sir God bless you it was really very helpful❤

greetings from germany, here we calculate the equations not only the max. values, but it was helpful. but i have an example and i wish that you can help me with it how can i send it to you sir ?

Proud to be a subscriber of exergic channel ...even I am from civil engineering background...I am always eager to watch ur lectures 🙏🙏
