Air machines are devices that use air pressure or movement to perform various tasks. Common examples include fans, which circulate air to cool spaces, and air compressors, which store and compress air for powering tools. These machines can be found in homes, industries, and vehicles, playing essential roles in everyday life. Another type of air machine is the airplane, which uses wings and engines to fly through the atmosphere. Airplanes rely on the principles of aerodynamics to lift off the ground and travel long distances. Overall, air machines are vital for comfort, efficiency, and transportation in modern society.
