Sir, Your teaching is simply awesome and you keep pulling our attention by saying " This is going to be interesting".....Thanks a lot

[@hanishkumar5701]

This man’s teaching style is something a normal teacher cant teach. I would like to thank youtube if this platform was not there we would never came to know that this gem is teaching one of the toughest subject in engg in such a simple and nice way. Very very thanks to you sir😍😍

Honestly sir you are a God gifted teacher for all Engineering Students

[@minatozakisana3350]

Sir, thank you for all of your great lectures. We appreciate it and I really like your teaching style. I do hope I can learn more from your videos particularly this quarantine season. You've always reminded us to keep learning and we would as long as you are the teacher. Keep it up, Sir! God bless. Thank you.

[@ManasPatnaikofficial]

All the best

Ur way of teaching is superb sir.....

[@deveshipatro]

Respected Sir, you are really awesome, your teaching skills are brilliant... I am able to grip all the basics on this subject only because of you... The way you are teaching each and every topic in a detailed manner with such positive energy is really appreciable and it motivates us to polish our concepts clearly and thoroughly. Thank You Sir.

[@ManasPatnaikofficial]

Thank you Deveshi...... When you all comment and appreciate my work, it motivates me to keep going..... God bless....

[@shreyashshankar9819]

It's soo long; that's why they don't teach this in college. They just give the relation. Good work Sir.

[@SanthoshKumar-wx9xx]

And remaining are super the way u r explanation.

[@RamiAldawoodi]

Hello Manas, You did a great job. Could you please post a lecture about 3-D stress analysis including the cases of plane stress and plane strain for concrete with respect of change in Temperature and Moisture when cement is poured and internally cured in soil and fixed between two rigid bodies which hold it from deformation in the Z-axis? Thanks again and again for the great lectures.

[@r4raatz]

Hi sir.. I have a doubt in the derivation where normal stress is proved to be equal to shear stress. In triangle ACD, A denotes the area of the planar surface [29:44] (as you mentioned clearly in 3d of the same triangle). But when you calculate for the cos45 where as of the formula the "a" denotes the length of the adjacent side. But you took A which is later canceling out the A area which was the planar surface when you submit (A/cos45) in place of AC in the formula "normal stress = (2 x shear stress x sin45) / AC. Can you please clear this out??

[@ManasPatnaikofficial]

I have got to see that video again Rajesh......Errors happen.......will get back to you asap.

Thumbs up for you sir

[@goldentimes7304]

Thank you very much sir. Helpful ❤️

[@SanthoshKumar-wx9xx]

At 29:27 if we consider thickness of the cube is unity then the area is to find logically good when comparing to consider as 'X'

[@rahulkori8175]

At 30:00 .. why two perpendicular forces on AC do not cancelling each other like tangential

[@devilmaycry5697]

The two forces are only cancelled out if they are acting in opposite direction to each other. But since they are in same direction, they will be added.

[@mallikarjunv3041]

@@devilmaycry5697 i think thats not the question in triangle ADC nd BDC both have 2Tsin45 stress why dont they cancelled out as similar to tangential stress ?? can you pls ans me??

[@rashtrawaditarun]

@@mallikarjunv3041 as we have cut it into two parts...if we take one part at a time then we cant cancel... If two parts are taken then it will get cancelled.. and thats why your whole system is in equilibrium... Hope it will help..

Thumbs up 👍🏻 to you sir 🙏

Hello sir , I got a doubt here in the relation of young's modulus and rigidity modulus why u have taken poissons ratio as positive towrit the lateral strain of NORMAL STRESS N1

[@susrisailazamishra5155]

Again I’m thanking you sir...

[@venkatasuryajanardhanarao2864]

Why the forces Pn& tasin45 are not cancelled out even they are opposite forces? Please explain this sir

[@megh280193]

Beautiful teaching, I am working as a scientist in ISRO, URSC. Thinking of Giving Gate 2021. I never have liked Strength of materials during my Aerospace Btech. I was thinking of skipping the whole structure portion itself, as for us only qualifying score is required, but believe me you made me reconsider my descision. But I have one doubt, when you are talking about shear stress why are you making shear stress on all the four sides of the representative Square element ? Means one couple half arrow on top and bottom should work nice enough for shear stress . Because once you make on all the four side you need to fix two sides, as couple cannot be generated otherwise. CORRECT ME IF I AM WRONG ....

[@srinivas580]

Top and bottom force creates couple . in som we consider body is in equilibrium hence to equalize there will another couple acting opposite to that of first couple hence there will be four shear stresses

[@rahulkori8175]

How angle in finding relationship between E and G comes to 45°

[@devilmaycry5697]

If you draw a diagonal from sides of a square, the angle will be partitioned into two parts of 45° each

[@amuldangi5047]

Agar square na le toh??

[@ranvirsingh-sc9ep]

Sir what if there is a shear stress also on the cross section.
