IIT - JEE : SHM : lecture 12 : Torsional pendulum

TORSIONAL PENDULUM :
In torsional pendulum, an extended object is suspended at the centre by a light torsion wire. A torsion wire is essentially inextensible, but is free to twist about its axis. When the lower
end of the wire is rotated by a slight amount, the wire applies a restoring torque causing the
body to oscillate rotationally when released.

Thanks for this explanation

[@physicsguru1]

Glad it was helpful!

[@defencewithloverajkoshyari1962]

Tqs sir

[@christinareji8362]

Helped a lot... Thanku sir

[@physicsguru1]

Do subscribe and also see ray optics
That too might help

[@ayushprasad3709]

Thankyou sir 💕💙

[@physicsguru1]

I am happy u understood
Do subscribe

Thank you sir 🙏❤️

[@sathvikmalgikar2842]

great video sir thank you

[@physicsguru1]

You are welcome

What is the role of mirror in the torsional pendulum (as it is mentioned in ug textbooks)

[@physicsguru1]

To measure angle of deflection

[@mradulmemes89]

What is the value of 'I' coming?
Is it 25 * 10^(-5)?

[@smitanayak_]

Torsional pendulum is there in jee mains syllabus???? Plz answer

[@a.kzestos2085]

I don't think so

[@mradulmemes89]

@@a.kzestos2085 then what it is??

[@physicsguru1]

yes it is there

[@smitanayak_]

@@physicsguru1 ok

[@learn.together4]

Very nice bhut zabardast
Sir SHM or waves ko plz aik playlists bna k daal dy

[@physicsguru1]

Hai na playlist th-cam.com/play/PLkczDQRkJ0FeuF-y3Q1qdY3NpelzuZrKv.html

[@fakharzaman102]

Nice

[@physicsguru1]

tnx

[@over-scrupulous]

Can you please explain how it comes [α=-ω²θ]

[@physicsguru1]

Like a=-w2x replace linear terms by angular terms
I hope u got it
If know let me know ill explain in detail

[@victormaxwellpeters9771]

Sir why acceleration is omega squared x??

[@physicsguru1]

you can watch the complete video or just skip to 29:00 th-cam.com/video/MgHiL-wrHWI/w-d-xo.html

[@victormaxwellpeters9771]

@@physicsguru1 yes very intustic video but omega squared x is quite familiar it seems like the x component of centripetal acceleration. So are they correlated??? If yes then how sir.

[@JahareenaAbdul]

Sum ka process batado sir

[@physicsguru1]

Can u elaborate what exactly u want

[@ponderr]

What about work sir due to this

[@physicsguru1]

Work method is different...we have solved using force torque method
