Nanoscale Size Quote by K. Eric Drexler
““Deep in the nanoscale-size range, however, engineering encounters ultimate, atomic constraints on the size of even the simplest devices. Gears, shafts, and bearings, for example, can’t be made smaller than a few nanometers in diameter, simply because mechanical components must contain enough layers of atoms to provide suitable shapes, surfaces, and mechanical properties for the devices to function.””

Source Book: Engines of Creation by K. Eric Drexler, 1992
At extremely small scales, physical limits of atoms prevent making mechanical parts smaller than a few nanometers, restricting device design.
In simple terms: Atomic size limits tiny mechanical parts.
