How Was the Wheel Invented?
In its earliest, most primitive form, the wheel was just a circular block of stone, the center of which was bored to form a whole into which an axle bearing could be inserted to allow for creating more complex structures. The exact time when the wheel was invented is not known, but supposedly, the wheel came about as the result of a process that took place during the Neolithic Age. The initial wheel is considered by many experts to be the invention that made rapid technological development possible during Copper Age and Bronze Age.
According to historic evidence, precursors of the wheel as we know it today were used in the Middle East in the 5th millennium BCE. The first wheels that were easy to turn were used for making pottery starting with 3500 BCE and the first evidence of using wheels as components for means of transport also dates back to around 4000 BCE, to Mesopotamia. The usage of the wheel-axle vehicle spread across the world very quickly – the first depiction of a vehicle that used two axles and four wheels dates back to 3500 – 3350 BCE and was found in Poland. The period was also marked by adjustments and amendments to the original concept – units that used rotating and non-rotating axles were developed to meet specific regional requirements. Today – you can find many variations of wheels and operations, and the driving schools in Denver offer maintenance classes to inform you how to change tires and keep them maintained, so you are safe on the road.
