U taught this topic better than most of the teachers in Indian coaching who who prepare us for iit adv and stuff. Thank u😗

Bruh I’m here for the same purpose

clean explanation and straight to the point. thanks

can't concentrate on the physics cause his backwards writing is too impressive

He is writing normally but the video is flipped. You are now free to concentrate. ;)

Thanks a Lot Sir, You made is so easy, as I saw a lot of derivations which has no explanation for dm

thank you! you explained it way better than my teacher did

MIT: making worlds best tech people Also MIT microphone: we use raw audio with noise

woah very nice explanation

How do we calculate if the disc is inclined at an angle to the vertical?

Thank you so much Sir

Why we have taken dm x r^2 only as difinetion of MI of rotational disc

Thanks

thanks

Since total mass is constant why couldnt we have integrated like this m ∫ r^2 dr from the definition of inertia

The mass of the total disc is constant however when we consider smaller mass elements the only thing constant is the mass 'distribution'/'density'. So you can't take dm out of the integral!

Sir can we slove moment of interia of a circle by considering triangle strip. If can please tell me how to slove

If you want to compute that I think you're gonna use how you compute for the area of a shape in polar coordinates, so you start from θ=0 to θ=2π and then do the rest

2:51 How can you say that the 2nd order differential dr is zero as dr approaches zero but the first order differential remains unchanged?

Considering the fact that dr is very close to zero, dr^2 can be approximated to 0 because it is way, way smaller by the same factor dr, which is already extremely small.

Use a calculator. If r = 0.001 then r^2 = .000001 and so on and on. You can see that dr^2 will approach 0 within that limit.

How are you writing this ...I'm confused! Are you writing mirrored or flipping the image?

Rotate 90 degree to left /right

Why should r be the integration variable, why can't m be the integration variable?

@LerAnd-hm9fe

Isn't the mass constant? Maybe that's why.

The DM is the tricky part

This is wrong,,,Icm of disc is=MR^ 2/4

@kelvinadimas8851

no, its 1/2 mr^2

@Lucas-yh5zz

i'm kinda late but 1/4 MR^2 are the momments of inertia tha correspond to the x and z axis that are parallel to the disc while 1/2 MR^2 is the momment of inertia of the y axis which is perpendicular to it

Thanks

thanks
