🔴 Elasticity - 6 || Determination of Young's Modulus || in HINDI for Class 11
In this Physics video in Hindi for class 11 we explained how to determine Young's Modulus of material of a given wire.
A typical experimental arrangement to determine the Young’s modulus of a material of wire under tension. It consists of two long straight wires of same length and equal radius suspended side by side from a fixed rigid support. The wire A (called the reference wire) carries a millimeter main scale M and a pan to place a weight. The wire B (called the experimental wire) of uniform area of cross section also carries a pan in which known weights can be placed. A vernier scale V is attached to a pointer at the bottom of the experimental wire B, and the main scale M is fixed to the reference wire A. The weights placed in the pan exert a downward force and stretch the experimental wire under a tensile stress. The elongation of the wire (increase in length) is measured by the vernier arrangement. The reference wire is used to compensate for any change in length that may occur due to change in room temperature, since any change in length of the reference wire due to temperature change will be accompanied by an equal change in experimental wire. Both the reference and experimental wires are given an initial small load to keep the wires straight and the vernier reading is noted. Now the experimental wire is gradually loaded with more weights to bring it under a tensile stress and the vernier reading is noted again. The difference between two vernier readings gives the elongation produced in the wire. Let r and L be the initial radius and length of the experimental wire, respectively. Then the are of cross-section of the wire would be pi X r^2. Let M be the mass that produced an elongation ΔL in the wire. Thus the applied force is equal to Mg, where g is the acceleration due to gravity. The Young’s modulus of the material of the experimental wire is given by
Y = σ/ε
Y = (F/A)/(ΔL/L)
Y= (F × L) /(A × ΔL)
Y= (Mg × L) /(A × ΔL)

Sir you are soooooooooooooooooooooooooooooooooooooo great.......😊😊😊😊😊😊😊
Thanks sir for covering each and every topic in such a comprehensive way
Liked before watching Love your Videos Sir❤️❤️❤️
Very nice video sirji thanq for Putting great effort for all students...Thanq on behalf of all students🙏🙏...
Sir, if possible, please also make such an animated video on vernier callipers and screw gauge it will be very helpful for me and probably others also. Your teaching is fabulous sir. Thank you.
Sirji ekdam maja aa gaya . Thanks a lot
Hello sir prnam aap ka lecture sbse best hai
It was an amazing experience to watch ur video, it was short and to the point !!!
Sir, thank u so much ..... there is an another level of peace in your video means without any background music or any disturbance........my ears got stocked here ...
Easily understandable
thank you sir. your explanation is really clear.i love it
Sirr channel aur video boht sahi h I loved it ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️ thankyou sir ❤️❤️❤️love from Nagpur Maharashtra
Super fantastic outstanding mind blowing sir n thank u
You sir have gained a subscriber
Best explanation sir...🥰🥰
Really good explanation sir 😊
SIR JUST LOVED THE WAY YOU EXPLAIN THANKS ❤️❤️
Very good explanation. Thankyou
Bahot bdhiya sir
Nice sr keep it up..... Beautiful ♥️
Helpfull vdo sir
thank you so much sir...
Sir, apne bhot accha samjhaya Ha
Awesome video sir thanks a lot 👍
very well explanation sir thank you
Thanks a lot sir for this wonderfull explanation
Thank you very much sir
Thank you sir you made my life easy 🙏
Editing level 👏👏
Excellent video its help me a lot
Thank you for your support sir 😘
Thank you sir 🙂🙂
Thanku so much sir
Every thing is all right Sir but something is missing that was numerical I hope you will do something
👍
Very nice explanation 😄😊😊😊😌☺️😊😁☺️😄
Please sir create a playlist on elasticity by adding all the videos of elasticity.
Nicely explained in hindi Sir. 👍
Awesome vdo like 👍it😄😊
In transmission of light waves, the angle between plane of oscillation and plane of polarisation. Answer it sir ji
Dusre wire me normal scale ke place per vernier scale kyo use kiye?
Thankyou sir ❤️😊
Thank u sir
thankyou sirr🙏
Thanks
Sir ,is this Searls method?
your way good#Brilliantcoaching

Ap agar collage level ki physics or electronic pe video bane too meri kafi help ho gi, I understand more in your video.♥♥♥
sir can this video helpful for iit jam
please add video on integration
Nice video
Nice lecture haaaai
Sir Bsc 2nd year ka optics pe vidio banaiye please

Ncert big gay I thought this topic was some complicated shit
"Operation amplifier" pe video banaea, please
Young's modulus is proportionality constant, so how does it's value change with the change in physical dimensions of material?

Yes... I was thinking the same thing

actually its not a proportionality costant . the proportionality constant in this is modulus of elasticity. it is just like all other formulas we have, we have the formula of young modulus.

refer stress strain curve d(stress)/d(strain)=Y
Sir flip flops pe video banaiea na.... Plz Big fan sir........
After elastic limit stress becomes 0 then y it is showed tends to constant in graph
Sir you destroyed every coaching class
Thank you so much sir ✨🙏🏻

Haai nhi hai
Haii bhai haiii kuch baat haiiiiiii
Legend has came here in February 😂👍
Young modulation hai bekar Isko quantum way main seekho ? So easy whole universe physics become a calculated quantum 🕉🕉🕉🕉
Thanks a lot sir
Thank you sir
