| The Archimedean screw |
|
| |
In ancient times, the Archimedean screw
was turned by men or animals. It was used to raise water from
wells or pump water out of the holds of ships... Today, it is
operated with a motor. It is also used for raising sand, mud
and wheat.
Its principle: a pipe is coiled into a spiral, like a big screw.
When it is rotated, water rises with each turn of the handle. |

| The wall of gears |
|
| |
The gears transmit movement
and enable direction and speed to be changed. The connecting
rod (which makes locomotives move), the piston or the Maltese
cross are mechanical systems used to transform movement. Gears
are used in many machines: car transmissions, locomotives, drills,
etc. |

| The manipulator |
|
| |
In the laboratory, the
manipulator enables dangerous products such as radioactive substances
to be remotely manipulated. The machine reproduces the movements
of the user's hands, using cables that link the grip to the
claw. |

| Measure your speed |
|
| |
Equipped with photoelectric
cells, this machine measures speed. Two light rays control a
chronometer which starts when the first light ray is cut and
stops when the second ray is obstructed.
The computer then calculates the speed of the runner between
the two cells. |

| Manufacture your badge |
|
| |
It takes just two minutes
to manufacture a customised badge before your eyes. In series,
four machines handle each stage in its manufacture: dispensing
of the raw material (the sheet), engraving the name and the
drawing, cutting the sheet, delivering the badge. The whole
process is controlled by computer. |

|
| The electron microscope
|
|
| |
The child observes the
same samples as under the optical microscope and discovers the
possibilities of this observational instrument, which enables
exploration of the infinitely small. |
