The era of "wheel" movement

The exhibit consists of four types of wheel hub devices and graphic boards, including wood, iron, aluminum alloy, and carbon fiber composite materials. Through a display format that combines mechanical interaction with graphics and text, the public can experience the differences in weight, performance, and other aspects of wheels made of different materials, and feel the tremendous promotion that material development has brought to social progress.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

(1) The invention of wooden wheels was around Mesopotamia. At that time, the wheel was actually a round wooden stake, and primitive humans used several wooden stakes placed side by side under the load-bearing object to roll forward. Over time, people began to improve wooden wheels to enhance their stability and handling. For example, in the 1st century BC, the Romans used wooden strips to support wooden wheels, making them lighter and more convenient. The wooden wheel hub is made up of several hardwood boards spliced together, with a hole in the center for installing the shaft. It was very common in early horse drawn carriages and some old-fashioned cars. (2) The invention of iron wheels can be traced back to the Iron Age, around 1000 BC, when the Celts began using iron rimmed wheels on their two wheeled carriages. Iron wheels are made of cast iron or steel. Iron wheels are heavier than aluminum alloy wheels, but the production cost is relatively lower. In modern cars, iron wheels are usually used as.
