Hey there...Im civil engineer and clear gate19 and preparing for MPSC pwd ..i hv never seen such awesome video in youtube..thankyou guys for your effort..god bless you alll❤️
I'm from England but have Pakistani heritage and understand urdu/punjab I i know this is hindi based but still obviously understand it and I love this. It makes it so easy to understand the concepts which is the basis for being good at mechanics of materials. I love it. Thank you❤️
thank u sir......aapne bhut acha padhaya..mera som bhut hi week tha.par aap etna acha padhate h ki mera confidence ab badh rha h.plz upload more video of som....thank u so much sir.. bcoz aapke jaisa kisi ne mujhe ni padhaya...
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.
Outstanding sir...... Bahut acha concept hai sir aapka harek topic pe.... Sir compound stress ka next lecture via banayiye... Gate 19 ka exam bht pasand hai... Som me sirf isi pe doubt tha jo aaj avi tak bht mast concept mila... Plz sir iska next video vo daliye gate exam se pahle
@@venugopalsharma1945 Yes, if the element is taken on the surface then it can be the case of biaxial loading. But you said.. ek element cylinder mein lu then, the whole concept is different. Anyways, I didn't mean to point out any mistake. You are making great videos.👍
Very nice presentation. The points are pin pointed and clear so that it helps in good note preparation. The discussion is to the point. Please continue this format in all videos.
I believe that the example of balloon inflation (rectangular element on the inside) for biaxial loading is not correct. However if we consider any section on the surface( square element on the surface) of balloon being inflated it will more accurately depict the example of biaxial loading.
yes you are absolutely correct but the thing is in thin section we generally considered the state of stress to be biaxial considering the various theories offailure even if you consider the state of stress of an element in inside surface as biaxial it wouldn't make a big difference in your calculations
In that cylinder example it will also have stress in Z direction also right since pressure exerted in all direction is constant so how it will be example for biaxial stress?
Particularly this lecture was delivered with nice slides(Animated), Could you please tell me the triaxial loading situation with practical example, just like 2d cases of gas cylinder/balloon..? Thanks
Hey there...Im civil engineer and clear gate19 and preparing for MPSC pwd ..i hv never seen such awesome video in youtube..thankyou guys for your effort..god bless you alll❤️
Even I am preparing for MPSC 2021. I have a few doubts regarding the syllabus. Can you help me?
Much appreciated.
In case of pure shear does the shear stress value is zero on principal planes ??
In case of pure shear does the shear stress value is zero on principal planes ??
@@anuragkhati4547 yes shear stress is zero on principal planes whereas the planes on which shear stresses acts are never free from normal stresses
Brother can you share you contact no,just want basic info about your studies😊...

Diagram se concept clear Ho jate hai sir... Kafi helpful hai diagram ki help me pdhana
Honestly...Maine aajtak venugopal sir jaise conceptual teacher nhi dekhe❤❤❤
Great sir.
Never seen such type of lecture.
Apka ehsan kabhi nhi bhulunga... Bahutahi accha explain kiya hai apne. Thank u
Love you sir ji....first time who have clear my concept..🙏
Editor Ko hat off..!
Brilliant
sir please jaldi jaldi saare lectures upload kro.. bht accha explain krte ho aap.. acche se smjh araha h saare concepts
Really sir I think you are the inspiration for all of our teachers in specially west bengal 😁
The best content on youtube for mechanical engineers
One of the best Teacher ,I've ever seen ,Really I am able to connect the concept to numerical problems for Gate. Thankyou Sir!!😊
Great video sir aap deep me aur bahot acche se samjate ho Thank u so much.... Gate acadamy andThank you so much Venugopal sir.

Thx foro the CLEAR explaination of the Principal stress concept
Sir whi treeka accha tha jsme aap marker se smjhate the 🥲🥲
WOAHH THIS PRESENTATION IS SOMETHING NEXT LEVEL 💥😍
U r too good sir, esa to coaching vale bhi nhi padate
Great video sir keep it up sir
I needed to recapitulate my MOS to study Machine design. This video was very helpful and to the point. Thank you v much🙏
Excellent Sir. Understood
Liked this video for the animation quality. 👍
very good explanation plz come in pune and start ur classes
A great teacher with strong concepts and a nice presentation. Love from Pakistan
Awesome teaching sir ji... Thank you so much
Extremely impactful video sir
Outstanding sir......
Bahut acha concept hai sir aapka harek topic pe....
Sir compound stress ka next lecture via banayiye... Gate 19 ka exam bht pasand hai... Som me sirf isi pe doubt tha jo aaj avi tak bht mast concept mila... Plz sir iska next video vo daliye gate exam se pahle
Best explained
Sir U are outstanding... thankyou sooo much
good presentation. I liked it.
Amazing concept clear 🇮🇳🇮🇳🇮🇳
Excellent sir 👌👌👌
thank you so much it was interesting and very easy , may god bless you and your family ,
Best platform best teachers.. wish you all the best sir . Thannq so much for awesome lectures.
Thank you Sir, your lecture has cleared many doubts of mine.
you got a new subcriber ....congrantulation sirji
Pranam sir ji ....u are unique🙏🙏🙏
gas in cylinders and balloons are an example of triaxial loading...it tends to change L , B, and H of the cylinder or balloon..............
gas cylinders or baloons tends to increase in length and diameter... there is no b and w...
Awesome quality
Awesome presentation... Never seen like this..
Our teacher taught us with the same figures which you have but I understand yours clearly .
Super Lecture , great vedio editing
Nice effort by the way
Good video sir pls upload all module video ..
🙏🙏🙏wah sir thanks a lot for providing full concept of principal stress...
Very nice concept sir
Thanks you so much sir....your teaching style is awesome..😊😊😊
Thanks sir. Your lectures are amazing.
You very well explain that sir i have to learn a lot from you
thanku sir
Examples of Biaxial loading are incorrect. Balloon, Cylinder are triaxial (3D) loading cases.
Agreed.
You are wrong its for thin member
If you take element on the surface its 2d

Sir you are great personality
thank sir your giving a quality education ......
Sir thankuh so much
To do this....type of support for us.. keep it up....
Thank you for your all videos
Thank you sir ❤️💖
Wow Explanation....
Sir, you made my concept clear.
Sir u r great teacher
Please sir upload next module.. We r very enthusiastic to see ur lacture..
Your speech of delivery is very good.. We are very much helpful with you..
Adbhut sir
Superb video
Sir you are God.🙏
Wow! Thank you ❣️❣️

Exactly! It is example of triaxial loading
Sir at time 12:05 , aapne Pn force bahar ki taraf kyun liya, andar kyun nahin liya
bcz k loading tension (expansion) mai howi hai eis liay plane pai b outside show ho pa raha hai...
Well done sir
Keep it up
Som video ke liye thanks sir, agla module kab tak ayega sir
amazing explanation thankyou
Sir one video on theories of failure please
Cylinder, balloon etc are examples of tri-axial loading
Excellent
Sir please upload lecture on deflection in beams ..
Explain about complex stresses and strains
Thanks bur sir also upload lecture of thermodynamics.
Superb sir
simply wow! you are a great teacher and the editor did an amazing job as well
Sir please upload theories of failure lecture
I see ur video lectures are good but I don know hindi so Pls upload lectures in English for aspirants from another language
But balloon and cylinder are 3D so they can also become examples for triaxial loading 5:46
Sir jo padha rahai uskha diffinition bhi likiyai or deatails mai padhayai
Sir mos ke videos continue upload karte rahiye
Salutes to you sirji
thanku sir , thoda jaldi karva do som ke ye topics
Particularly this lecture was delivered with nice slides(Animated), Could you please tell me the triaxial loading situation with practical example, just like 2d cases of gas cylinder/balloon..? Thanks
Thick cylinder , hydrostatic loading and many more
Sir, what is the difference between the thick cylinder and cylinder (gas cylinder) in above lecture ?
Thank you
The plane on which normal stress is max with bonus of shear stress to be zero is principal plane.
Really helpful sir
Thnku sir . .for this lecture
Nice video
pressure inside a gas cylinder acts across all axis right ?? same with all axis..
I like video sir
Happy birthday Sir
