🔴 Elasticity - 9 || Poisson's Ratio || in HINDI for Class 11

- In this Physics video in Hindi for class 11 we explained Poisson's ratio and derived its formula. Poisson’s ratio for a material is the negative of the ratio of lateral strain to longitudinal strain of a body made of that material. When a body is deformed such that it experience a longitudinal strain, it experience a lateral strain also. In general, when a body is streched, it becomes thinner. But auxetics are different. Auxetics are structures or materials which become thicker, when stretched.

आपका समझाने का तरीका बहुत ही यूनिक और अच्छा है कृपया मेरे बच्चों के लिए कक्षा 12 के भौतिक विज्ञान के प्रयोगों की वीडियोस प्रयोगशाला इंस्ट्रुमेंट्स की सही-सही रीडिंग्स के साथ बनाने की कृपा करें । ताकि थ्योरी के साथ-साथ प्रैक्टिकल्स स्किल्स भी बहुत अच्छी हो जाए । क्योंकि अधिकांश स्कूलों में प्रैक्टिकल्स के नाम पर केवल खानापूर्ति की जाती है ।
धन्यवाद ।
But Mark's toh chahiye
In order to honour the scientist who discovered this ratio,the norm must need to be continued.
Perfect sir hai aap
Yes
Deep knowledge mind blowing sir, sir keep it deeply teach us sir plzzzzzz
great sir..
I thought I know everything regarding Poisson's Ratio, but you proved me wrong. You are too smart.
i like the video sir many many happy diwali sir
sir how is 0.3=3%
as in 0.03 is 3% right ??
thanks, sir
sir, I love to your explain pross which is so interesting
Hlo sir..
I'm Aamir..
I feel very glad bcoz this chennel is very helpful for me..
Thx a lot sir..
Thnq sooooo mchhh
Its rlly get help in my studies..
But I want to confess & request for one thing that :-
Please make a vidios on chptr 15 (WAVES ) & remaining chaptrs of chemistry..
Please sir..
I request to you..
& thxs again for providing such a geart help to us
Thnq soo mchh😊
You are an excellent teacher; nice explained
Sir, you explains in very very simple manner. Thanks 🙏
Sir, jaldi physics par videos banao. Because I love your teaching ways.
Superb explanation sir❤❤
Perfect se bhi perfect Sir ho app
Sir u teach technically ,logically, ur way of teaching create a bit of scientific mind in us, but alas! Here are most of the teachers who does not impact on the concept , their teaching way is just to solve numericals , queston etc, but i dont want to study only for qualify a degree on competiotion i just want to achieve knowledge, i want real study sir ,the teachers like u are should be saluted,
Nice sir
Awesome
Please sir do explaination of Ch-equilibrium of class 11 🙏🙏🙏🙏🙏
Nice Sir 👍👍👍👍
Your Handwriting is awesome sir. Omg I m fan of your handwriting😍😍
So simple 😂 ... Just use Modulus 😎.
Sir can u make same video explaining in english
Great sir ur work is very knowladge oriented.
Sir I like your videos
Wavelength dispersive spectromy please upload a video on this .. u make nice videozz
Sir please make video on voltage divider rule.
Thank you so much sir😊😊😊😊😊
They should have just used modulus in place of negative sign to keep things normal
THEN IT WILL DIFFICULT TU UNDERSTAND WHICH ONE IS auxetic AND WHICH ONE IS normal MATERIAL.
IF YOU LEARN SOMETHING IT DOESN'T MEAN YOU CAN APPLY IT EVERYWHERE
Sir, Can you please make some math playlist? like complex number,binomial,matrix...?? please reply me .
Sir mera ek doubt hai,ki agar ham kisi material ko pull karte hai to kya uski longitudinal dimension or laterally dimension me linearly increment or decrement hota hai,sir mujhe lagta hai ki jab ham kisi material ko pull ya push karenge to uski dono dimensions me linearly change nahi hota hai,kyonki jab ham kisi rubber ko pull karte hai to janha se use pakdte hai vanha to vah wide hoti hai or bich me se kam wide hoti hai,esa hi steel wire me dekhne ko milta hai,to fir poisson ratio ki value kaise sahi aa sakti hai,,,sir plz clarify this doubt,,
I am from Pakistan.
And my gratitude for you is immeasurable.I have got 90 marks out of 100 in my 12th just because of your lectures. You would be amazed to know that Sir I have choosen the field of accountancy and doing ACCA now
But Still I watch your lectures despite of the fact that there is zero relevancy with my subjects.
I have been following you since one and half year.
Trust me You're the most lovable teacher. Take care of Yourself.
Love ❤️💯
A passionate student out there! 👏
Sir please aap koi chij avishkar kijiye....👌🤞 Best of luck my very talented sir
Gr8
Zordar sir
Superb concept😍😍😍
I request you to add other videos of physics of class 11 as far as possible.
Sir apke samjhane ka tarika hi alag hai
Polytechnic electrical engineer 2nd ki subject wise taiyari karaye sir for board Jodhpur ki
Great explanation sir
Please sir confer a video discussing the theory-"bending of beams" and "internal bending moment"
Sir why are you not making videos
My. Best teacher
Thank you very much for your huge support and encouragement.
@@edupoint.physics you are one of the best physics teacher out there.
Thank you sir for this topic
Osum teaching sir 👍👍
Sir aap video editing ke liye kin software and tools ka use karte ho
PL----zzz tell about something
Best teaching sir
Sir u are my favorite
Nice explanation sir
Sir plz back!!
Sir thank you very much ....
Sir plz make a video on *"MOTIONAL EMF"*
Sir please make video for class 12 chemistry sir I'm only see your videos thanks sir
Sir plz make a playlist for radiation... Plank radiation formula full derivation + weins low plz sir 🙏🙏🙏🙏🙏
Great voice Sir
sir please digital electronics nd application topics pe bhi video bana lo nd CRO ki bhi
Sir i am big fan of you
Can you put a video on bsc mathematics
Luv u sir
Great sir 👍👍 keep it up
8:02 to exam me kya likna hota hoga 🧐🤨
Please sir create a video on Photo electric cell
Sir chemistry bhi pdhao. And always nyc vdo
Sir please make video on ions
Sir u absolutely right
Sir plz Bsc physics ke note dijiya
Nahi banaya...
Sir mera ek sawal hai,length to scalar hai to length ko vector kyu kaha gaya hai ampere law me
Sir please tell me best book for IIT JEE MAIN PREPARATION
Sir please make videos on heat
Sir please upload some videos on Flip Flops and explain clock for flip flops.
Thanks in advance 😊
Thanks sir 🙏🏻🙏🏻🙏🏻
Sir superb
Very helpful sirji....Sir jarurat nhi h sayad change karne ki kyuki Hum roj- roj auxetics k sath Rubaru nhi hote sayad...
Good....
Sir ek sawal h ki auxetics to kam material hi hote ho gye?
Yes.
Wikipedia me search karein.
Kaafi details milega.
@@edupoint.physics thanq sirji🙏🙏...Mai jaa k padta hu wikipedia me...
@@edupoint.physics sir....kya aap koyi auxetics ke example denge?
Superb sir
Very nice sir
excellent
Nice
Sir, please modulus of elasticity ka video banayiye...
Available.
Sir what is a mesh in a circuit?
Also want biology all chapters 11th std 2019-2020
Nice experience
Sir please class 12 chemistry ka chapter 2 ka Raoult's law ka video banaiye na mujhe samajh ni aa Rana hai.🙏🙏
Please make more videos s
Good morning sir....
Class_11_Chap_11_thermal properties of matter.....
isko complete Kara dijiye sir.....
Please......... Mujhe aaj 11.9 heat transfer and 11.10 Newton law of cooling ka topic padhna hai...
Bilkul change hona chahiye sir
Sir bloch theorem samjha dijiye please please jaldi us per video banaiye
Sir ji
jaise x axis ko absisa
And y axis ko ordinate bolte hain
Waise z axis ko kya bolte hain ??????
Ravi bhai,
Thank you for the question. Maine kabhi socha nahi tha. Keep asking....
Saud bhai,
Thank you for the answer.
Mujhe aapse pata chala ki z axis ko applicate kaha jata hai.
Nice😄
Sir bsc ka thevenins theoem or Norton's theorem ke bare me video bano samajh me nhi ata he
Sir aik video complete bana den higs boson par
The Norm(putting -ve in the ratio )shouldn't be changed but Auxetics should be treated as Exceptions or a new ratio for them should be introduced.
Sir please keplar ka 1st law explain kijiye bsc 1st year
Flux kesa dikhai deta hai
Sir aap video kaise bnate h mere ko engineering related bnane h
Sir dual nature of radiation and matter abhi baki he o finish kar dijiye
The norm should be changed!
Happy diwali sir h
please sir
😰😰😰😩😩
Make a video about p,d,f block
how .3 become 3 % at 12:08
same question sir
Hmari book me negative sign nhi h positive sign h btw amazing video
Norms should not be changed I think
- ke jagah mod kyo nahi laga dete...
