KEY VOCABULARY
Word Meaning
pneumaticcontaining or operated by air or gas
under pressure
pneumatic
system
a fluid power system which transmits
force through compressible air
compressed airair that is at pressure more than
atmospheric pressure
vacuum a space entirely devoid matter
valvea device for controlling the passage of
liquid or air through a pipe, duct, etc.
innovation a uniquely new idea, device or method
Air is all around us even though we can’t see or feel it. Air
presses on our bodies with a great force. We don’t feel this
because the air inside our bodies is pushing back equally
hard. Air pressure is know as pneumatics and is very
important.

PNEUMATICS - DEFINITION
• The study of pneumatics deals with system operation
with air to impart power or to control power.
• The term pneumatics is derived from the Greek word
pneuma, meaning wind or breath.
• Pneumatic power is the power that is transmitted by
pressurized/compressed air.
A BRIEF HISTORY OF PNEUMATICS
Most of the modern machinery we see today uses
some type of pneumatics to make it function.

New York City
pneumatic mail system
1897
Pneumatics was discovered in
the 16 th century by a German
physicist and engineer named
Otto.
He experiment with air and the
idea of compressing it and
invented the first vacuum pump.
that used pneumatic force.

HOW DOES THE HYPERLOOP WORK?
1. There’s a tube (tunnel) from point A to B.
2. The air from the tube has been removed
(low air pressure is present inside the
tube).
3. Then there are some pods inside that
tube.
HOW DOES THE HYPERLOOP WORK?4. These pods will levitate and move forward tracking friction and
reducing drag (as the air has already been removed).
5. For some air left in that tube, compressor fans installed in the
front of the pods will suck in the air and push them via air bearing.
6. Anything can be put the pods, depending upon its dimensions
and capacity.
7. These pods will move from point A to point B, moving the things
(or people) in them.
