Professor Vandiver ,thank you for a beautiful lecture on the Mass Moment of Inertia of Rigid Bodies. These lectures are preparing students for Advanced courses in Mechanical ,Civil and Aerospace Engineering.
thank you mit for the free course.
23:35 I think he is looking for the term Eigenvector?
Thank you mit
What a teacher!!

22:18 -> 22:30 no it will not always be dynamically balanced! Rotating a body about its minor or major principal axes will remain dynamically stable. However, rotating a body about its intermediate principal axis will always lead to instabilities. This is demonstrated in the classic tennis racket problem.
You can say it's balanced but not stable.
We were taught this concept during undergraduate course and it's very important topic for iit entrance exam.
They teach the topic so much better than my college
Hi maaadaham
Super Professor.
9:54 sounds like "little ass particles"
great
This is epic!
Grt sir
What would a proof look like to prove that any object you throw that rotates will do so about the COM
So easy
Conservation of linear momentum.
What is the physical interpretation of product of inertia ? e.g. in beams the area moment of inertia is resistance to bending and in dynamics mass moment of inertia is resistance to rotation then what does product of inertia means?
products of inertia describe the asymmetries of mass in the rigid body
nicely done...btw this is an undergraduate course so those who found this awful might needs to brush up their fundamentals , kids ! you didn't understand it because this might be your first lecture in rotational dynmics and guess what - you directly hit to the intermediate level without passing through beginner level !
..
and his explanation is better than my indian instructor !
👌
~ 26:10 "Where to put? You want it down here? Oh you want it like this, OK."
Oh come on! 😂
what is the principal of mass moment of inertia for rigid body? i want answer ,please.
It really has little to do with ethnicity. This poor soul simply has a very monotone voice and is quite low energy, but that appeals to certain students, and not others. Some indian professors are so horrendously awful at teaching you wonder how they tricked the faculty into hiring them, while other who are indian are excellent. Generally speaking though the handicap with any foreign professor is their ability to communicate in English, not just their accent. Sometimes it is difficult to explain technical concepts for a foreigner, when they lack the vocabulary necessary.
Спутник для увеличения скорости на 10км\ч, потребляет Х кг газа. Почему Х кг газа не может ускорить спутник до 1 миллиона км\ч?
What??????
Please in English
Has anyone read the short story "the billiard Ball" by Issac Asimov?
He uses a pool table and an anti-gravity/inertia ray to remove all of a moving billiard balls momentum, effectively giving it total inertia, pinning it to the Higgs field. causing the ball to instantly disappear from the table, leaving a hole in the professors nemesis, and the wall behind him. The earth moved from the ball This theory has rattled in my head since i read the story in 1981. Why cant this work, and what
Indian teachers can teach far better than this... :(
I think he's not bad. He asks a lot of questions to the class which makes people think. And he uses physical objects to illustrate rather than diagrams on a 2d board.
You have a point bro.... Indian teachers are way better
+shashank saxena hes better than my indian maths teacher. so...
+shashank saxena but nobody speaks indian.
You're watching this for free but you're complaining? Makes sense. At least I can I understand him...
This was a very boring lecture😏🙄. I wouldn't stay for this lecture it's too much unnecessary information
Not good as Walter Lewin....
This is not high school physics.It does not even make sense to compare.
Anonymous ... it's not about high school or master degree , bachelor degree.... it's about teaching method ... that makes student to learn interestingly in particular subject......
@@painpeace3619 Grow up. You come here to learn, not to have someone make you learn things you don't enjoy in a fun way.
You retard
