1. Advance Illustration | Rigid Body Dynamics | Equilibrium of two Planks on a Rough Plane

The website, aimed at nurturing grasping power students, has classroom lectures on almost all the topics. It is an outcome of 23-year long toil of Physics expert who has made it a mission to simplify the complexities of Physics.

Ashish Arora, the brain behind this interactive unique website, has all his lectures available on web for free of cost. He has created a youtube channel in the name of Physics Galaxy. Today more than 6000 video lectures are being watched per day on this website which is highest among any other e-learning website in India. Till now more than 3.6 Million videos are watched on it. On each video subtitles are also available in 67 languages using google translator including English, Hindi, Chinese, French, Marathi, Bangla, Urdu and other regional and international languages.

Besides uploading transcripts of all his videos, he has created a software based synchronized European voice accent of all videos to benefit students in USA, Europe and other countries.

@ suvrath hegde,   these questions are collected from various academic resources developed by various physics experts for prepartion of competitive analytical physics as well as international physics olympiad.

[lakshya]

Thanks a ton sir !
You've provided content of this level accessible to needy.
Advance Illustrations+ Concept Videos+ Revision Checklists =💯

[kumarshekharsingh]

Sir are these videos very helpful for advance preparation..I want to ask that are these questions designed for jee advance purpose also..plzz reply and thank u so mch for giving us ur precious time sir..😊😊😊

[englishplanet]

Sir i enable to get pg booster classes notes in pg app after the class where could I find that...plz help

[pranabray]

thank you so much sir! These videos are really helpful

[ravijaiswal]

sir where is 22 and 24.is missing????.please explain and thanks for doing everything for us god bless you sir.

[abdullabohra-jm]

am here to leave a mark so that in life i will get reminded by people liking or asking doubts or just being curious how did my paper went or how much marks did i score [i am saying i am a average student who will maximum can get 110 to 120 marks ]
that i had gone through some literal hell for this exam thank for reading this far

[meepishi]

sir, as rod is slightly tilted in its contact with the ground, why have we not considered a normal force in the x direction like that of hinge force ?

[KaranDoshicool]

Sir links of booster classes of Dynamics is not working on the official website.

[adarshmall]

sir should i try these advanced illustrations myself first or should i directly watch the whole video

[sushantnair]

Kon h ye 2 dislikes wale . Felt sorry for them as they took the like button as dislike👈👍👎

[ashutoshmanorkar]

why didn't you take the equation as f+mgsin() -T=0 as there will also be a force due to mgsintheta? please answer to this query?

[vedified-spiritual]

How can we say that friction will be muN only . The friction is static and value of friction can be less than limiting friction??
We should first write equation in terms of tension only and then tan that will come mg/2T then we can say that to minimize tan thita tension should be maximum.and maximum tension can be muN only.
Correct me if I am wrong, please

[abdullabohra-jm]

my two mistakes one silly error and second concept error
1.] i accidentally putted mgsintheta in place of mgcosthetha
2.] i took n=mgcosthetha

[rishabh]

Thank You so much sir for this gold mine😍😍😍

[sammyhoggers]

Sir, while using rotational equilibrium, why didn't you take the component of Normal force perpendicular to the rod?

[abdulansari]

sir why friction is u, N it can be less than or equal to u, N since it is static friction ? plz reply soon

[CEBMDAQUIB]

Can we take torque about com instead of A

[dochrishistrange]

Thank u sir very much for making such quality content accessible.

How To =mg think it's l/2 sinΦ and answer will be independent of Φ
