Machines of Ancient China
A lot of the inventions really attest to how more advanced Ancient China was in science and technology.
Simple machines are the foundation of all complex and large scaled machines. From the point of view of classical mechanics, there are four simple machines: lever, pulley, inclined plane, and screw. From the lever, shadoofs were invented. From the pulley, wheel-and-axles, and cranes were invented. The inclined plane evolved into wedges, or into screws when the wedge was coiled. Construction technology also had simple machines such as ropes, chains, hinges, linkages, cranks, wheels, gears, and springs. Vehicles included both manual, and animal-drawn carts. They were some of the oldest means of transportation, hauling and also military vehicles. To use an animal to pull a cart, to operate a mill, or to plow the field, an effective harness first had to be custom made to address the unique shape and form of the animal. The invention of the harness was an outstanding achievement which opened the door to many other developments. The compass-equipped “south-pointing chariot” (zhinan che) and an odometer-equipped chariot called the “li-recording drum chariot” (jili guche) or hodometer were two brilliant inventions that incorporated machines in vehicles. As for animal powered machines, the eight-wheeled ox-powered mill (niuzhuan bamo) and the field mill (chemo) were first invented by the Chinese in ancient times.
They wondered with a goal, and they explored with direction.  It can be said that, based on their early inventions, they created because they valued the gift of life highly. They sought not only to exist, but also to live. To merely go throughout life breaking one’s back for daily meals did not appeal to them. They created tools such as the wheelbarrow and trip hammer that would help alleviate the workload of everyday life. They created games such as Cu Ju and Chui Wan that would allow one to enjoy life. They created practices and medicine to sustain life. They created things such as the early seismograph and star maps to understand life and the world around them (Hochman, Karen). They also created weapons, but not with the primary purpose of destroying life, but with the purpose of protecting life and protecting order.
Major mechanical elements and mechanisms of ancient Chinese machines, such as linkage mechanisms, cam mechanisms, gear mechanisms, and flexible connecting mechanisms (ropes and chains), were invented.
