One of the best lecture i have ever found on RU-vid. Just Amazed. Recommended to all.

Helpful especially in lockdown,

I am so thankful to you respected Human ...FOR SPREADING YOUR KNOWLEDGE in a good manner .

Thank you so so much been struggling with this for a couple of days and now all of my doubts are gone in a second !

Salute u sir u devlop a great level of understanding of this imp topic. Sir I think this is the best lecture with full clarity. Sir please make lecture on torsion.

sir u are amazing.... Love from Pakistan

sir.. before watching ur video i couldn't understood this topic but after watching this.. I am believing that it is too easy.... sir plz make more video on different different topic which is too complicated.. specially #Compound_stresses..plz sir...

Amazing, fantastic explanation with step by step. Vary easy explanation

Superb Sir. Thanks for explaining such a complex topic in such easy words.

Very nice video sir, as said by you my concept are now too clear on this topic of strength of material...I request you to please make more such videos on complicated topics on the toughest subject "SOM".....it will really help many students.. Thank you sir

This video just made my life less miserable. thanks.

Ary sir bhtreen hogya

Thanks Manish Bhai. Cleared my concept in very short time. Nice to see your channel.

Most genius teacher sir. I have seen many good faculty,but are technically horned teacher sir.

I will recommend to everyone before watching this video let's watch it's previous one Max strain energy theory's video And thanks sir great level of teaching style 🙏🙏👍

Kya faadu padhaya hai sir , ekdam easiest way

best explanation of this topic.. Thanxx sir.....

Wow incredible!!!!! Sir you're doing a great work

Really helpful. Explained very well. It would be great if you could include how to determine safe regions diagram for all the theories.

Your way of explanation is amazing.Thankyou so much

Thank you! sir it was the best and most understandable brief of TOF.......

Tum bahot mast kaam karta hai Manish bhai.

Wooooohhh.... love it👍👍👍👍

Dil se shukriya❤

Sir Gate exam aa rha hai.. aur ek deflection of beams pe aapki video ki jarurat h...

Short and to the point. Very informative.

You are awesome sir... thank you so much

sir....................superb lecture, very excellence ...plz make vedio on different different topic

Really good job.... You explained it really well and got everything you said ! 👍

And sir in maximum shear strain what is G..

Sir the way you teach it simply awesome

Firstly I thought 30 min class would be a lag, but you just fired it up.

Thankyou very much sir your teaching style is great.

superb video very clarity

Good job sir ji.......👌👌👌👌👌

Woohhh... Love it📣📣📣

Sir, you taught this theory in practical way....nice explanation. Thanks.

You have nicely planned and explaied brilliantly

Superb explaination sir👌

Sir, how to find principle stresses when an object is subjected to 3 dimensional stress?

Sigma 1 is tensile and sigma 2 is compressive then what will be maximum shear stress?

Thank u so much sir U have just implanted theories of failure in my brain permanently U r the best

Well done sir

Sir no words for this explanation..u r great😘😘

Thank u sir finally I understood this concept

posted one generation ago and helping every generation since

Really sir ... ur reaching style is superb....plz upload hole topic of som......plz plz

Excellent

Thank you sir g you r best and also mentor of my who is not able to afford fee of made easy

thank u sir every doubt was just cleared in video i want ur more & more lecture videos (humble request)

Great , Sir ji

dear sir you told every complex state of stress can be expressed in terms of three principal stress .can you please elaborate this line .i am eagerly waiting for your response.

Great

Sir please make videos in English, the explanation is awesome,but I do not Hindi.

good method of teaching

One of the best lecture i ever found on youtube. Thanku sir.

Perfect sir ji...👌👌

You didn't include the effect of external shear stress. But it was informative.

Excellent concept clarity,great method of teaching too...Thank u sir...Keep posting 😊

🙌🙌

Sir you...missed the graphs of each concept... i.e.....hexagonal....sqare.. .etc..

Good,it is easy to understand

Short and well explained 👌

Thank you sir, for this very very conceptual and lucid teaching

Superb

Superb lecture sir please make more videos

Max. Shear strain energy theroy mai correction in 2d eqn.. S1^2 +S2^2 - S1S2...

Sir you are great teacher really

Very very good explaining sir...thanks sir

If the values are given as sigma x , sigma y, sigma z not principal stress then how do we apply shear strain energy theory?

Sir u just nailed it..here is a big thankyou

Very well explained . Thanks a lot .

Sir please increase your camera quality

great

Sir, regarding the concept that u told that in 2d stresses there is always third principal stress with magnitude equals to 0 and when max shear stress is to be calculated under the condition that other 2 stresses are tensile then it will be simply the greatest principal stress-0 and divided by 2 But sir see question no 11 gate mechanical 2009. What should be the answer for this

one of the best lectures that i could find !

is it ultimate tensile stress or strain?yield stress or strain?

Good evening sir 👍 Sir I am a student of diploma.. Sir I have a query that how will be going to know that this is the maximum stress or strain we can put on a material.. 🙏❣️

Excellent explanation..

Very nice explanation sir...Thank u very much

Sir stress strain diagram me jb yield point se beyond le jane ke baad unloading krte hain to wo parallel to initial tangent ( E) hota hai .. Lekin sir mera sawaal ye hai ki unloading point wala stress ,true ya engineering stress & strain lenge? Is baaar gate me aayatha set 1 me . Recovery after strain hardening. Is pr bhi ek video banaye Sir.

Kya padhaya hai yar, theories of failure, kammal!!!

You explain so good...thanks

Thankyou sir

Very helpful 👍😊

Very well explained

sir 3 dim me stresses ki nature nahi consider karate kya aur agar nahi kart to q nahi karte ye bhai sanjha dijiea

Nice explained.

Thanks sir such a great lecture

I have read it but my sir told that...sign jus shows Nature ...it itz 40 and -100 ...-100 is greater principal stress..

Good evening sir.. Aapka lecture bahut achaa hota hai.. Thank u so much.. Sir Mujhe SOM ka (SOM 1 & SOM 2) ka complete lecture chahiye. Mera SOM weak h. Aap koi link ya Video lecture provided kra dijiye sir.. Shear force and Bending moment ki wajah se Bahut presan hu. Plz sir help me.

Sir I have a question... Is the same maximum stress used for bending and torsion loading? I mean here you write the theory of failure equations due to axial loading bt will it be same for bending and torsion?

Thank you for your kind efforts

Thanks sir Add some concepts for solving problems

Too good sir.. 🫡

sir do you have a lecture on principal stresses and principal plane??

Sir plz make video on fluid mechanics asap

Thank you for the lecture

Thanks a lot
