In this video from Minute Physics youtube channel, host Henry Reich inserts a mass damper in Lego’s amazing Saturn V set to demonstrate how engineers prevent structures from shaking.
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.A tuned mass damper, also known as a harmonic absorber or seismic damper, is a device mounted in structures to reduce the amplitude of mechanical vibrations.
Their application can prevent discomfort, damage, or outright structural failure. They are frequently used in power transmission, automobiles, and buildings.
