Posted at 21:42h, 26 May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，，，。

Posted at 21:42h, 26 MayOk.

## 刘宇龙

Posted at 21:42h, 26 May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，，，。

Posted at 21:42h, 26 MayI feel like the school should teach mechanical vibration before quantum mechanics, since it helps a lot in understanding the wavefunction

Posted at 21:42h, 26 MayImagine paying half a million dollars to go to one of the best schools in the world, then they post all your lectures on youtube.

## Maham Hussain

Posted at 21:42h, 26 MayI 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.

Posted at 21:42h, 26 MayWhy can't my professors teach this clearly and not fumble through chapters like a 5 year-old reading a Harry Potter book.

## Max Abraham James

Posted at 21:42h, 26 MayIt is very satisfying to hear the sound the chalk piece makes with the blackboard.

## Castro Salvador

Posted at 21:42h, 26 Maysome 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…

## Niels Ohlsen

Posted at 21:42h, 26 MayThank you very much for providng us with such a great lecture.

## artem leon

Posted at 21:42h, 26 MayIf 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

## guduri harsha

Posted at 21:42h, 26 MayHi Professor thank you for the information, I didn't get the clarity on Phase angle

## Alter Kater

Posted at 21:42h, 26 MayEven me could copy from a paper to the blackboard.

## Bo Zhao

Posted at 21:42h, 26 MayWhen 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.

## ebiros2

Posted at 21:42h, 26 MayThis 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?

## dog

Posted at 21:42h, 26 Mayand meanwhile… my professor takes an entire lecture to derive one equation and solve one problem… why are we still here… just to suffer..

Posted at 21:42h, 26 MayI can not even imagine this teacher has a paper while teaching in MIT LoL hahahaha………

## Malcolm Anderson

Posted at 21:42h, 26 MayHaving 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

## MegaJohnhammond

Posted at 21:42h, 26 MayDid an MIT graduate design your chalkboard?

## Michael

Posted at 21:42h, 26 MayHe doesn't know what a phase angle is on the diagram

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

## Abhishek Gaur

Posted at 21:42h, 26 MayIs there some lactures on governor on mit? Pls share link…

## Anonymous

Posted at 21:42h, 26 MaySo far, one of the best lectures of the course, very good.

## Lalendra Kumar

Posted at 21:42h, 26 MayIs there anybody who can clear my doubts? I have some doubt while solving the problems.

## Usman Rajput

## Shen Kai

Posted at 21:42h, 26 MayWas this lecture for undergraduate or postgraduate students? Just curious

## astafzciba

Posted at 21:42h, 26 MayStudents at mit have no excuse of getting Cs or even Bs

## Benevant Mathew

Posted at 21:42h, 26 MayTime delay is phi(phase angle) over omega n(natural frequency).

## Anthony G

Posted at 21:42h, 26 MayHow do the k terms in (k1+k2)xs= L/2(k1-k2) cancel out????? @ 17:12 ????????

## Amal Suresh

Posted at 21:42h, 26 Mayexcellent

## M M

Posted at 21:42h, 26 MayThank 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?
