Презентация на тему: "The invention of the wheel"

Слайд 1

Слайд 2

A wheel is a circular component that is intended to rotate on an axle. Колесо - круглый объект, который вращается на какой-либо оси.

Слайд 3

The wheel is everywhere, on all our cars, trains, planes, machines, wagons etc. But as important as the wheel is as an invention, we don't know who exactly made the first wheel.

Слайд 4

The oldest wheel found in archeological excavations was discovered in what was Mesopotamia and is believed to be over fifty-five hundred years old.

Самое старое колесо, найденное в археологических раскопках, было обнаружено в Месопотамии, полагают, его возраст составляет более пятидесяти пяти тысяч лет .

Humans also realized a way to move heavy objects, with an invention archeologists call the sledge. Logs or sticks were placed under an object and used to drag the heavy object, like a sled and a wedge put together.

Слайд 7

Wooden pegs were used to fix the sledge, so that when it rested on the rollers it did not move, but allowed the axle to turn in-between the pegs, the axle and wheels now created all the movement. These were the first carts.

Слайд 8

Even in Europe, the wheel evolved little until the beginning of the nineteenth century. However, with the coming of the Industrial Revolution the wheel became the central component of technology, and came to be used in thousands of ways in countless different mechanisms.

Даже в Европе, колесо мало развилось до начала девятнадцатого века. Однако, с приходом Промышленной революции колесо стало центральным компонентом технологий и стало использоваться в различных механизмах.
