No entendi ni madre de lo que hablo el maestro, pero se ve que vacila un poco al comienzo de la clase, hasta tiene que ver los apuntes en el papel que trae en la mano, porque no se acuerda de las formulas. Yo recibi clases de calculo de un alumno ayudante en la universidad que tenia la capacidad de resolver problemas de calculo aplicado, mentalmente; claro que necesitaba de una calculadora cientifica para entrar los datos numericos.

That is the better way to explain all Mechanical Vibration basics I've never seen.

Fine, such a fantastic Lecture! Isn't it?

Right now, seeking the complete course…

nice job. Thanks

東大と問題はどっちの方が難しいのかな

AAAAMMMMMMAAAAAAAZZZZZIIIIINNNGGGGG

you should hook air tank up to an air piston motor. a challenge to build one and drive your go carts around. When you see it works you can build one for your car… I have designs for one on my you tube channel….never pay for fossil fuels again… hope this brings a good day to the world around….or use it to run a generator

Thank You! 🙂

VERY GOOD VIDEO, MAKE ME CAN EASY TO CALCULATED Mechanical Vibration.

you have not explained the other 4 methods of deriving the differential equations. You do not state that other methods exist. It is a misleading lecture at the start.

check https://www.youtube.com/watch?v=Ki3hh-Lb_4M out for proper list of methods.

this is very good and super course of Basics Vibration.top prof.

great video

Great lecture but at minute 48:38, there is an omega term missing after the plus and minus. isn't it?

test

Great- But it is Pend a lum, not pendge a lum.

For some reason my original test message did not go through, so I'm sending a longer one, in the hopes that this one does Perhaps the first one was just too short.

i wish study in america really …in my university there is not even a chair to sit on it

This is awesome, man my high school is so basic, I wish high schools would introduce these types of courses. Is it weird that I'm watching a lecture on mechanical vibrations and I'm only 15, I've been reading some thesis papers on Quark Matter so it's nice to take a beak and learn a new topic. If anyone wants to learn about or learn more about quark Matter, here's a link. https://arxiv.org/abs/astro-ph/0407155 go to the section on the right, where it says PDF

som super explain

wow …the basics have been taught very nicely

Just stumbled on this while working on a dynamic balancer. I hadn't seen this good of a simple derivation of spring, mass, dashpot in years. It flowed nicely like an old song and warmed the cockles of my heart. Stu Fields BSEE

Its really fantastic & i am very much convinced with the approach used to find out the critical damping. Thanks a lot for such a great lecture sir.

…and k1+k2 to the power of [WTF]^2 explains why these people have 0.0000001% chance of being good in bed!! If you understood more than 1% of what was taught here, you probably have no life, no friends and sex is just a biological thing happening to other people. But you probably know how to assemble a vibrator and you will be rich selling dildos and love dolls. It is all about vibration, right?

sound is very low

I agree with Dr. Vandiver up to a point. The kinetic vibration from a K1 and K2 facilitated solution has to be met with proper centrifugal force applied properly. I am excited with the new development of Euler's Formula to prove true kinetic energy displacement. MIT has allowed me to broaden Euler's Formula and has allowed me to truly invent the way kinetic motion through displacement exists. This will actually be covered in my theses. 7.5 years at MIT and I am finally starting to visualize the light at the end of the tunnel.

Amazing lecture. Really explained the mathematical ground-work and the physical meaning behind it.

intellectual masturbation. Not terribly applicable in the real world. Give a real world solution for stopping destructive vibration at a range of frequencies.

nice .perfectly.

at 1:02:09 added mass is not the correct reason for that because gravity works independent of mass.specially in case of simple harmonic motion. it may be resistance offered by water that is may be drag force.

i think so

This was awesome. Thank you. Very straightforward explanation of the basics.

This is really a perfect introduction to vibration theory, Prof. Vandiver really made it easy to digest! Strongly recommend this to you all.

wonderful presentation

What a great professor…….he uses examples to show natural frequencies of various objects and then mathematically explains it. Vibration expertise is very important to Engineering but is very difficult to learn. You must do many problems before it "clicks".

please,how do I reduced vibration in a yam pounding machine

Just one problem: I do not like when professors read notes in their classes… They should study it before…

Thank you sir for your lecture

Want to get one of those empty seats…😍😍😘

Does anyone know where v can watch others lectures regarding vibration

what is the reasons of natural freq. ? and what is the energy is produce this freq. ??

ezberci sistem

You are amazing, thank you

thanks for improving of engineering knowledge

What an outstanding lecture! He laid out the foundation for vibrations perfectly. This lecture has made me consider MIT for my master's degree.

We are all created by vibration! Everything is

16:48 Why are they equal?

To engineering students is study help to me this is rocket science

I really enjoyed the lessons thanks teacher and I'll like to get your books and i don't know what to do so i can get them

Watched the whole class, would like to applaud for great refresher of stuff learned 30 years ago.

Thanks for uploading.

I really needed this. I'm taking structural dynamics this semester and the first lecture I received was a 3hr class that lecturer didn't stand up once to explain anything. He sat through the whole class and read from his slides. Thank you for this

Great lecture

Thank you.is there a formula which tells the proportions of vibration.for example is the next vibration is a 25% of the main one and the next to it is the 50% of the main one which has the main vibrated wave?

excellent

How do the k terms in (k1+k2)xs= L/2(k1-k2) cancel out????? @ 17:12 ????????

Time delay is phi(phase angle) over omega n(natural frequency).

Students at mit have no excuse of getting Cs or even Bs

Was this lecture for undergraduate or postgraduate students? Just curious

This is why MIT is MIT

Is there anybody who can clear my doubts? I have some doubt while solving the problems.

So far, one of the best lectures of the course, very good.

Is there some lactures on governor on mit? Pls share link…

He doesn't know what a phase angle is on the diagram

What he pointed to is (180-phi) and not phi itself

Did an MIT graduate design your chalkboard?

Having problems with vibration. Comes from downstairs a apartment below me.

I dont know how or why and my manager of the apartment can't help unless I can prove my point. So I am interested in any thing have to with vibration and how its cause and why someone use it and how they can make vibrates/Vibrations upstairs. HELP PLEASE

I can not even imagine this teacher has a paper while teaching in MIT LoL hahahaha………

Wow super

and meanwhile… my professor takes an entire lecture to derive one equation and solve one problem… why are we still here… just to suffer..

This knowledge must have been a holy grail to ancient people (and also to some of us). How do you compute Q from the damping ratio?

When I was in college, my lecturer missed dynamic part. It is very important and hence useful topic for practice engineers alongside with Fourier transform. Excellent lecture ! I am learning this part.

Even me could copy from a paper to the blackboard.

Hi Professor thank you for the information, I didn't get the clarity on Phase angle

If India or Muslims keep on praising themselves on how hard their university is or smart their culture is, how come they are in this lecture watching and commenting? LMAO

Thank you very much for providng us with such a great lecture.

Phase expatiation is wrong…

Kaio

There are some girls in a mechanical engineering class !!!!!!

Never been as bored in my life

1:12:10 My brain hurts just looking at those blackboards

alex trebek in disguise

Thank you ..Bless you

some statements that he does, are already copied from books, that why pupils do not comprehend from where the formulas or "solutions" comes from, because it look like spontaneous apparition in the solution of the equations. Pardon, but teacher really most understand that the people came to classes knowing Zero, and all the explanation of any mathematical, fisical, or calculus most, imperative start from Zero, meaning in the level that they start…. VIBRATIONAL equation become more and more intrincate, and if the students do not get the initial knowleges…they will just VISIT THE CLASS ROOM…

It is very satisfying to hear the sound the chalk piece makes with the blackboard.

Why can't my professors teach this clearly and not fumble through chapters like a 5 year-old reading a Harry Potter book.

I was able to learn a lot more than i already knew about Mechanical engineering because of the following website. It has a number of courses in it that a learner can take and once you take the course you get a lifetime access to it.

Imagine paying half a million dollars to go to one of the best schools in the world, then they post all your lectures on youtube.

I feel like the school should teach mechanical vibration before quantum mechanics, since it helps a lot in understanding the wavefunction

博士好深奥，作用力和反作用力以及动能加浮性防阻和速度无反作用力，，，。

对了，若从出発点到高空再順时針方向或逆时针方向呢?，以前，而直上测或斜上测从动能以及矩離上的时问点和动能上，顺时针或逆时针或钭右上或斜左上，，，??。

只剩控方向陣列以及接收発波原理了，，，博士太猛了，，，。

Ok.

This video is the reason that I finally learnt damping . Thank you so much!

如果柱撞击後，向上而不是左右作用力，音擴会比較久，因为柱的空气圍作用力，而向上的作用力，非←排音，，，。

Great explanation. thanks, from brazil!!!

Why aren't there lectures for 2.004, Dynamics & Control II, MIT OCW? So many course on OCW for Mechanical Engineering lack lectures…many courses lack lectures. Wish it would get filled up.
