dm/dx= m/l (this is because the rod is assumed to be uniform, hence the mass per unit length ratio is same for any arbitrary piece of the rod) dm=(m/l)dx ( by multiplying both sides by dx)
m/l tells you how much mass there is per unit length. but the dm entity aint a unit length long, its infinitesimal small(dx). so to get dm (mass) we multiple dx (length) with m/l (mass per unit length)
@@mognokhan1701 yep... cos they teach you whats required.... for us they just say fk off, go learn everything we too lazy to revise the books. they don't remove outdated portion like how to use those old inaccurate af equipment or how they work, etc... only portion that has scientifically been proven wrong because they kinda forced to.
Dr Dourmashkin, Brilliant Presentation.
Thank you very much,I was so confused before I see this video
THANKS A LOT!!
thanks
I love you! Thanks alot
bit late to the part but amen for this vid
Thats a Grade 11 easiest question
I dont understand how dm equals m/L dx
dm/dx= m/l (this is because the rod is assumed to be uniform, hence the mass per unit length ratio is same for any arbitrary piece of the rod)
dm=(m/l)dx ( by multiplying both sides by dx)
m/l tells you how much mass there is per unit length. but the dm entity aint a unit length long, its infinitesimal small(dx). so to get dm (mass) we multiple dx (length) with m/l (mass per unit length)
Amazing
beautifull
really helpful
🙏🙏
Cool
Mm the red marker is fun
Very nice.
nice professor I want to study from you at MIT.how can I get there?
people learn this in college? indian schools teach this in 11th grade.
😅😂rght, i am in 11th and tomorrow is my exam... So i am right here
For the lil doubts in integration 😆 part....
They will teach you the same thing in college too. And to be honest, NA's education is easier than Asia's.
