its amazing to see how well he articulates his thoughts ,sometimes pausing to get the right words. Succinct descriptions of the otherwise complex hard to explain things !
I'm here at the penultimate video of this lecture series. Thank you so much for these! These have been a part of my journey through my vibrations class and I'm quite grateful.
Professor Vandiver, thank you for a real world lecture on the Response of Two Degree of Freedom Systems by the Use of Transfer Functions. I took this class at the old Catonsville Community College in Catonsville, Maryland in 1985 and my professor was very bad. The professors at MIT are incredible. These lectures are of the learning charts.
In current skyscraper buildings many engineers uses "optimally tuned and damped dynamic absorber" to counter building oscillations. An example is the Taipei 101. This man is by far one of the best teachers I've heard in a long time.
@1:08 - does the absorber act like a beam in such that when it is moved further away from the point where the force is applied, it causes the node to shift closer to the point of applied force?
I have one question though. At 21:00 you assumed the excitation frequencies are the same. How would you solve for the equations of motion if the forces were acting at different frequencies?
