The invention of the wheel in about 3500BC enabled mankind to make use of rotational motion. The wheel is one of the six simple machines that allow us to change the direction or magnitude of forcesForce. It is considered to be one of the most important inventions of all times. We think of it as revolutionizing transportation, but it has many very different uses such as a water wheel or a potter’s wheel. Some of the themes of the chapter are represented in Fig. 4.1.

摘要

The invention of the wheel in about 3500BC enabled mankind to make use of rotational motion. The wheel is one of the six simple machines that allow us to change the direction or magnitude of forcesForce. It is considered to be one of the most important inventions of all times. We think of it as revolutionizing transportation, but it has many very different uses such as a water wheel or a potter’s wheel. Some of the themes of the chapter are represented in Fig. 4.1.
