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".

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.

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.

​@@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.

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?

I think it's because xs is the displacement of the block in the static condition, meaning it's not dependent on time. This makes it a constant. Left and right side of the equation are equal meaning they can both be subtracted out of the equation.

The main reason is money. MIT contributes 1M+ every year to MIT OpenCourseWare. Even with that funding, we are only able to record a limited number of full courses each year (~12 courses). We try and prioritize which courses we can publish by a number of factors. Unfortunately, 2.004 has not made the video lists. Maybe sometime in the future we will get funding and time to recording 2.004. We do have materials for 2.004, just not videos: ocw.mit.edu/courses/mechanical-engineering/2-004-dynamics-and-control-ii-spring-2008/. Best wishes on your studies!

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?

Are all mechanical engineering courses this hard or is it just MIT?
