They are gases, usually air.

Fluids are used in Hydraulics - fluids are essentially incompressible - they transmit forces well (e.g. a car bottle lack) Gases are used in pneumatics - gases are compressible - you can therefore store energy in a pneumatic system (e.g. a car tyre)

pneumatics consists of using air or gas to do work. hydraulics use water or a liquid to do work both gasses and liquids are considered fluids

Pneumatics is a method to transfer energy from one point to another using actuators which which are driven by fluids under pressure. Pneumatics restricts itself to gaseous fluids while hyraulics uses liquids to transfer the energy. The transferring of energy in pneumatics such as pumping air into a pneumatic cylinder must be controlled. You can control the pressure by manually opening a valve, automaticall by detecting its pressure, or by sending an electrical signal. The cotrol of pneumatic components by elecrical impulses is known as electropneumatics. This science is fast expanding as it can make use of all electronic developments such as PLCs and PCs. However electropneumatics has restrictions as it cannot be used in places where electricity cannot be used such as gas factories,etc. jacob m

a disadvantage of hydraulics is that if the pipe breaks the oil or other fluids will leak all over everything. Where as pneumatics uses gas when a line breaks when using pneumatics it wouldn't spill

Pneumatics have been used for thousands of years, ever since hunters used the blow-gun to take down their prey.

In an Automobile Pneumatics is used in tyres, breaks, suspension speed control and time delay

hydraulics is the use of liquids particularly hydraulic oils as a medium to create force where as pneumatics also used air.

In road works. The massive pneumatic drill that makes all that noise lol

Pneumatics is the branch of physics or technology concerned with the mechanical properties of gases. And that's what "Pneumatics" mean

Pneumatics could be used in a system like at the bank drive-through to shoot the container through the tube, or air powered tools, such as nail guns and drills.

Pneumatics is the use of pressurized gas to affect mechanical motion.

It is extremely essential in Hydraulics and mechanics. Your car would not run without pneumatics.

My thoughts go like this...(from watching 'Scrapheap Challenge"0 plus a little basic knowledge of physics. 1/ Pneumatics involve the movement of pistons and what not via the medium of compressed air or air under pressure. 2/ Hydraulics involve the movement of pistons and what not via the medium of compressed fluids or fluid under pressure. 3/ Fluid is denser than gas (compressed air). I believe hydraulics can handle far heavier loads than pneumatics. Pneumatics would appear to use a lighter more flexible medium than hydraulics. In answer to your question, I believe hydraulics would be far more effective at manipulating heavy loads versus pneumatics. However, pneumatics would be a more flexible system than hydraulics. Hows that?

it compresses and expands gas so i would say pneumatics but not in the normal sense

pneumatics are used only in low power applications hydraulics are used in medium to high power applications.

easy: Both use pressure now hydrolics used liquids (liquids cannot be compressed) to exhert pressure pneumatics uses gasses which are compressed to exhurt pressure thtas the basics anyway

In a nutshell, pneumatics is a means whereby signals and energy are transmitted, controlled and distributed using pressurized air as the medium. Pneumatics can be effectively combined with other technologies through the use of sensors, transducers and microprocessors

The body fluids shift out of the blood vessels and into the interstitial space. These fluids are used for re-hydration.

Each one has its own advantages. Generally hydraulics are more powerful while pneumatics are less expensive overall and simpler to maintain. Pneumatics are also generally cleaner environmentally. Pneumatics can also be pre-pressurized while hydraulics cannot. Hydraulics tend to be better for large things, like heavy machinery. Pneumatics tend to be better for small things, like cars, robots, and Legos.

It can be used as just a fun experiment for kids learning what non newtonian fluids are. It can also be used to show what viscous elastic fluids are.

pneumatic is a medium to control valves, through the tiny tubes{just like electricity through the wires}.....

I'll ignore the horrible way the question was asked.. Pneumatics use the flow of pressurised gas to transmit motion.

oil is slightly compressible 0.5 % at 70 bar. but air is compressible. so to get the required pressure pneumatics require more energy source than hydraulics also there are some limitations for pneumatics in terms of force.
