Cylinder 'Levitates' on an Oil-Coated Belt Running Like a Vertical TreadmillHere’s a surprising way you can defy gravity with a metal cylinder, a vertical treadmill and oil.Mohit Dalwadi at the University of Oxford, UK, and colleagues experimented with cylinders of various masses and several different treadmill belt speeds to model the conditions at which the cylinder will “levitate” whilst rotating on the oil-slicked belt.#fluiddynamics #levitation #physics #cylinder #oil #treadmill #lubrication
