    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".

    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.

    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.

      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.

    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.

    ⇒ 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.
