People have understood centripetal and gyroscopic forces for millennia. Centripetal forces are used in threshing machines to separate grain, spinning tops and hoops have been children's toys for thousands of years, and people knew an arrow with fins flew through the air better by imparting spin to the arrow.

Some of the first bicycles used driveshafts or interlocking gears. Transmitting power has been commonly understood since the middle ages. Gears were used to drive clocks, windmills, and irrigation pumps. How did the gears rotate without ball bearings, btw? Additionally, there are examples like the Antikythea mechanism that are thousands of years older showing a knowledge of gearing.
