🔴 Elasticity - 2 || STRESS and STRAIN || in HINDI for Class 11
Mechanical Properties of Solids - Part 2
In this Physics video in Hindi for class 11 we explained stress and strain from the chapter 'Mechanical Properties of Solids'. We also discussed on their types.
The restoring force per unit area is known as stress. The ratio of change in the dimension to the original dimension of the body is known as longitudinal strain.
Stress is of three types:
1) Longitudinal stress
2) Shearing Stress
3) Hydraulic stress
Longitudinal stress is of two kinds, viz., tensile stress and compressive stress.
If a body is stretched, the restoring force per unit area is called tensile stress.
If a body is Compressed, the restoring force per unit area is called compressive stress.
Strain is of three types:
1) Longitudinal Strain
2) Shearing Strain
3) Volume Strain
If a body is stretched by two equal forces applied normal to its cross-sectional area. The restoring force per unit area in this case is called tensile stress. If the body is compressed under the action of applied forces, the restoring force per unit area is known as compressive stress. Tensile or compressive stress can also be termed as longitudinal stress. In both the cases, there is a change in the length of the body. The change in the length to the original length of the body is known as longitudinal strain.
The restoring force per unit area developed due to the applied tangential force is known as tangential or shearing stress. Shearing strain is defined as the ratio of relative displacement of the faces to the length of the body.
a solid sphere placed in the fluid under high pressure is compressed uniformly on all sides. The force applied by the fluid acts in perpendicular direction at each point of the surface and the body is said to be under hydraulic compression. This leads to decrease in its volume without any change of its geometrical shape.
The body develops internal restoring forces that are equal and opposite to the forces applied by the fluid (the body restores its original shape and size when taken out from the fluid). The internal restoring force per unit area in this case is known as hydraulic stress and in magnitude is equal to the hydraulic pressure (applied force per unit area). The strain produced by a hydraulic pressure is called volume strain and is defined as the ratio of change in volume to the original volume.

Your teaching style is unique and good Thankuu... for this video
Sir aap please🙏.. 11 th ki physics k or bhi chapters pe videos bnaya kariye jisse hme or bhi aasani ho physics pdhne m .... because aapse pdhne k baad physics padhna bht aasan ho jata h .....hmare liye...it's really very helpful for us... fantastic teaching....👍👍😘
Sir I am inspired of your teaching style you tech concept in a special way every one can not do that ❤️❤️❤️❤️❤️❤️❤️❤️
Sir, awesome explanation 💙💙💙
Excellent explanation, thanks for the clear concept...👍👍

Thank you sir 🙏🙏🙏🙏🙏
👍 good and easy teaching techniques.
Osm sir I understand all concept 🤗🤗
Best sir you are my favorite teacher 👌👌
Your teaching style is different from other teachers
Thank you sir...😊😊😊
Thanks so much sir 👍👍👍👍👍👍
I love your explanation style
I m now mechanical engineer but still watching stress n strain
Thank you so much sir♥️!!
Your teaching style is unique and simple,so I request you sir please class 11and 12 ki chemistry and physics full package banado hum monthly paisa denge
Nice teaching sir great work sir.
This vdo is very easy to understood
Thanks Sir 🙏💕
Sir I have a question - If restoring force is equal and opposite to deforming force then why deformation takes place? Sir please clear my doubt
Sir if you make notes for students my friends like your videos sure your videos are most populate
Sir apka video bhut help kerta h topic ko phadhne me
Uncle you r 💯 teacher 🙂🙂
Really nice teaching sir Really good. 👌
Sir you are great
Thank you sir thank you so much ......
Sir you are the best teacher 🙏🙏💐🙏🙏🙏
Nice sir.. Thank you
Sir your dworing is so good

Basically both have same formula which is force per unit area Pressure is used in the cases of fluids (gas, liquid) And stress is used in the case of solids👍
Very very thanks sir
Thank you sir
In shearing stress, area which you have choosen doesnt have any changes in the atom's distance na sir? How can that be the area ?
Sir you are excellent .Sir aap video banane ke liye kya use karte h please batayen
Are bhaiya hum bihar se physics luver aur aap jharkhand se physics luver
Your teaching is nice sir
very very nice video sir
Good explanation sir😊🌺
Good work sir
Excellent
Sir area kon sa lena h stress lga n k bad wala ya phle wala
sir your teaching skill is very good and it is easy to understand to ,sir so i kindly request you to make videos very fast.....
Sir agr haam foot ball ko water me dalenge to vo to bahar ki taraf aayegi right 🤔🤔🤔🤔
Sir, agar book slide na kar ke haath se ya fir ek ungli se Water bottle,cup ya fir glass,box, etc slide kar diya jaye toh uska base aur uppar ka part dono he move karega na usme toh koi friction nahi lagega na sir?
Sir your 3D drawing is best❣️
Sir at 4:25 par agar ceiling bhi force lagaegi toh, phir upward direction mein 2 force that is deforming force and ceiling force par lower direction mein toh bas restoring force h then how restoring force equal to deforming force???????????? 🙄🤔🤔🤔🤔
Sir your drawing, writing and teaching skill are nice and helpful for us
Aapki drawing bahut achi hai sir
Love you sir
I'm first viwer.
Thanku sir
Sir class 11 and 12 ke lie kis physics,chemistry and math chunna chahie
Sir aap ek video Numerical Problems solution ki bhi bnaya karo jinse hame Aapka lecture aur achi tarah samaj me aa jaye
Sir app bahut अच्छा ड्राइंग करते हैैं
very helpful
Sir thanks sir
Please sir as soon as possible to make notes.
Sir physics HONOURS 3rd sem thermal physics par video banaye

Sir aap 11 class ki Kumar Mittal ki book ke numerical questions kraeye please
😊
जब आप कहते है की stress is the internal force of restitution per unit area. लेकिन जब हम tensile load applied karte hai to internal force हमारे द्वारा लगाए गए force ke equal and opposite direction me induced होगा तो जो internal force hai ya restoring force hai body ko compressed karne ki kosis करेगा । Us time jo stress hai wo compressive nature ka hona chaiye par hum use tensile stress consider karte hai aisa kyo??? Short me tensile force ke कारण कंप्रेसिव स्ट्रेस और कंप्रेशिव फोर्स के कारण tensile stress hona chaiye na।
Sir your explanation is so nice 🤞🤞🤗
