10. Advance Illustration | Rigid Body Dynamics | Normal Reaction on a Sliding Block | Ashish Arora

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.

i paused at 3:45 as it should be h/2, tried to understand for 10 mins...found nothing...resumed video...and..👀😅
thanks sir for these amazing illustrations❣💫

[liitkgp]

This same problem came in my advance pattern test

[factshub]

Sir why haven't u written friction as u× N ( mu × normal rxn)??

[Piyushthote]

@physicsgalaxyworld
Sir why not u considered torque due to mgsintheta???...

[sohamtripathy]

Is there a way to clear physics doubts using physics galaxy?

[ramandutt]

Sir wont there be any torque due to mgsin(theta) /??

[aritrapaul]

Sir, should we not take the torque about the left bottommost point as the block will tend to topple about that point?

[virenhaldwania]

is it the same case as that in toppling?

[abhisheksoni]

Sir will there be any torque due to resultant Mg

[cs__adityaverma]

sir why normal rxn shifts forwards and not in backward....

[serjeelranjan]

Sir can we write tan(theta) = friction coefficient

[vivekgupta]

Sir, even if uniform speed of body is not given, then same answer comes when we apply net zero torque about lower front side of body axis. It means extra information is given in Problem.

[rohanmeena]

sir please provide me booster class 2.4.2 videos

[liitkgp]

Sir I think it's problem of toppling

[gauravvyas]

Sir why you have written fh as torque due to friction ? Please explain

[techienauty]

torque of friction must be f*l by2 not fh by2
