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.
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.
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.
@williambradley835 Yes, I mean that the quality of this explanation is much higher than any that I ever received at my university. Of course, the engineering is the same, but instead of learning it from lectures we mostly had to teach ourselves!
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...
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.
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
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
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.
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
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.
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
I am really grateful for this content. It allows me to learn so much. Thanks you so much, MIT. I really appreciate it. I believe there's a "issue" in one of the equations. When the professor analyses the value of s for values of etha bigger than 1. I believe he misses a factor of w in the second term of s. 47:33

@@cult4037 Bro, you’re only in 9th grade chill out. You’ll be fine, don’t stress about this. This is an MIT lecture. Just keep your grades high and take the hardest level math and science courses available at your school. Pass those. If you enjoy the pain by then, you’ll be a great engineer.
cuz in a static analysis there is no motion, therefore no velocity and no acceleration so both x double dot and x dot are zero. which means (k1+k1)xs=l/2(k1-k2)
@@damianblandi4294 When ignoring the dynamic forces, (k1+k2)xs=l/2(k1-k2), which means when plugged back into the equation involving dynamic forces, you can cancel like terms. Think of "(k1+k2)xs" and "l/2(k1-k2)" in terms of a variable "x". if you were to rewrite the equation in terms of this new variable "x", you could subtract x from both sides and cancel them out resulting in cero.
I'm shocked that a professor at MIT makes such a mistakes! k1 × 𝛿1 = k2 × 𝛿2 𝛿1 + 𝛿2 = L ⇒ 𝛿i = ki × L / (k1 + k2) defining 𝛿 as 𝛿 = 𝛿2 - 𝛿1 then equation of motion is m × a = (k1 × 𝛿1 - k2 × 𝛿2) - (k1 - k2) × x where a is acceleration, the second time derivative of x at the middle. could it be any easier?
Hi I'm a autistic man with sensory difcultuys is there anyone who understands low frequency and vibrashion, I'm having difficulty with both, iv made a you tube Ja play, to show the vibration and app picking up the noise, i hope it's ok to ask. Thank you Jason

I searched for it.
I just searched it but hi!
Welcome
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
Watched the whole class, would like to applaud for great refresher of stuff learned 30 years ago.

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

So nice thanks sir
I'm shocked that a professor at MIT makes such a mistakes!
k1 × 𝛿1 = k2 × 𝛿2
𝛿1 + 𝛿2 = L
⇒ 𝛿i = ki × L / (k1 + k2)
defining 𝛿 as
𝛿 = 𝛿2 - 𝛿1
then equation of motion is
m × a = (k1 × 𝛿1 - k2 × 𝛿2) - (k1 - k2) × x
where a is acceleration, the second time derivative of x at the middle.
could it be any easier?
