Application of uniform
circular motion
1. Centrifuges - they are used to separate liquids of different densities i.e. cream and milk
2. Drying clothes in spin dryer- clothes are placed in a perforated drum rotated at high speed, water is expelled through the holes and this makes the clothes dry.
3. Road banking– especially for racing cars which enables them to move at critical speed along bends without going off the tracks.
4. Speed governor– the principle of conical pendulum is used here to regulate the speed by controlling the fuel intake in the combustion
chamber. As the collar moves up and down through a system of levers it thereby connects to a device which controls the fuel intake.
