This video is about Tuned Mass Dampers, which can be used to reduce or avoid unwanted vibrations, swaying, swinging, bending, etc on engineered structures ranging from buildings, skyscrapers, electricity power transmission lines, airplane engines, formula one race cars, etc. TMD's use damped coupled oscillators.
