Respect to the camera/sound crew! Very well recorded and filmed!
It is very satisfying to hear the sound the chalk piece makes with the blackboard.

A key part of what makes the MIT lectures so great to watch
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".
Thank God for people likethis lecturer!! Proud to be an Engineer! !

Watched the whole class, would like to applaud for great refresher of stuff learned 30 years ago. Thanks for uploading.
This is really a perfect introduction to vibration theory, Prof. Vandiver really made it easy to digest! Strongly recommend this to you all.

Fuck this explanation bcoz this is not modify vibration
So far, one of the best lectures of the course, very good.
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
Amazing lecture. Really explained the mathematical ground-work and the physical meaning behind it.
I am currently studying a mechanical engineering course in the uk and this video saved me on my CW when it comes to damped vibration and the experimental data analysation. amazing video keep doing what you love

Hi
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
Professor Vandiver, thank you for an incredible lecture on the Introduction to Mechanical Vibration. Mechanical Vibration is a very important third year class for Mechanical Engineering students. All students majoring in Mechanical Engineering should master these concepts before taking Mechanical Vibrations.
thank you for the lectures! Really enjoyed this one, even though it took me about two hours to get through it greetings from TUL, Czech Republic
Really nice explanation. Thanks, from India!
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.
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...
Que lindo, qualquer pessoa no mundo poder te a oportunidade de assistir aulas direto do MIT, como eu, aqui em uma pequena cidade do Brasil.

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.
Your simplifying how far it goes on a grand scale
great resource keep it up MIT
This was awesome. Thank you. Very straightforward explanation of the basics.
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.
I feel like the school should teach mechanical vibration before quantum mechanics, since it helps a lot in understanding the wavefunction

wow ...the basics have been taught very nicely
I need more lectures on Mechanical Engineering. Eng. Dynamics are good but I need others too!
Really nice videos! Congratulations!
Time delay is phi(phase angle) over omega n(natural frequency).
Thank you very much Professor and MIT service.
thanks for improving of engineering knowledge
this is why this school is called MIT, thanks professor
Really great content. Thanks!
Some of the greatest examples of vibration that people can relate to are tires out of balance and spinning washing machines out of balance..... Your shocks or struts in your car are dampers that absorb forcing functions such as potholes or seams on the freeway and hopefully keep you away from the natural frequency.
This was absolutely wonderful and helpful. Many thanks for sharing this video.
After seeing the quality of the instruction in these courses I understand why it means something different to go to these schools - compared to my 100% acceptance local engineering university... for a professor to exhibit this level of organization, eloquence, and lucidity is truly something special... would be fantasy at ATU...

In reality there’s only one way mechanical vibration works. Sadly if you were taught otherwise it was just incorrect. Some people are better at explaining to the masses than others but the solutions should be exactly the same.

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
Great explanation. thanks, from brazil!!!
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?
thank you so much, you make more easier for me
just awesome..
physical intuition of damping ratio (i.e. less the damping ratio doesnot mean it will vibrate for more time, it's actually take more number of cycles to decay the vibration amplitude) is lit

please solve this Mcqs Thank you. 1) All vibrating bodies have following Degree of Freedom: a)1 b)2 c)3 d)4 . 2) The frequency of vibrations with increase of damping in the case of free vibrations with coulomb damping will A.Remain the same B.Increase C.Decrease D.May increase or decrease depending upon the damping coefficient

merci monsieur pour ces cours
Thank you very much for providng us with such a great lecture.
nice job. Thanks
Thank You! :)
Thank you so so so much
Damn...it's been like 20 minutes into the video and I'm completely lost but surely entertained. I am a mechanical drafter but I'm considering going back to school for mechanical engineering and this is like Chinese to me lol. The hardest level of math I completed was trig and algebra 3. I thank this man for sharing his knowledge, so awesome :)

Jesus Carrillo that is probably why you can't get it. Iam currently coursing mechanical engineering and this subject belongs to my sixth term. Of course you don't get it, hahaha.
How could I obtain the relevant acceleration by taking into account the Fourier transform? Because if you use the Simple Harmonic Motion, acceleration will always increase as frequency increases. In reality, structures are affected by certain frequency. So, how can I consider both the peak acceleration and the frequency in which my structure will have resonance effects?
This is a essential lessions for students from 16-18 years old in VietNam. Too hard to study in that age

Do you take in that much detail of calculus, I doubt it!
Very helpful.
Why'd he use a dice? There are no dice.... e{a}/t=hv. A 5th above is a 4th below. So... can I put a KK2 controller board right next to the motor if I balance my prop with the motor? That's what I need to know before the operation..... Mass spring dashpot... I'll try to remember that term. Sounds important;-)
X refers to displacement
what is the reasons of natural freq. ? and what is the energy is produce this freq. ??
Hi Professor thank you for the information, I didn't get the clarity on Phase angle
this is very good and super course of Basics Vibration.top prof.
Wow I can't find a video now thay I can't find on sysmic vibrations and in hand with mechanical vibration but I'd like to hear your side on the matter I please sir
excellent
HEAVEN.

So nice thanks sir
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,,,。

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
