Each one has its advantages and disadvantages so it depends on what you wish to achieve.

You measure it with an aneroid gauge.
Pneumatics have the advantage over Hydraulics in that they are clean, require lower maintenance and respond quicker. When the application does not require that much force, pneumatics will do the job. Furthermore: the force needed for train doors should not be that large. It should only open and close the doors but not crush people that manage to get stuck in between
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)
Meter in and meter out circuits are not in pneumatics as air is compressible.Hence uniform control of actuators are not possible
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
hydrolics work using fluid under pressure what else stupid
Basically pneumatics deal with lower loadings, hydraulics offer a better power to space ratio, useful in say aircraft design.
hydrolics
with hydrolics
Pneumatics is the use of pressurized gas to affect mechanical motion.
you just spelled it
you dont
people
it compresses and expands gas so i would say pneumatics but not in the normal sense
In an Automobile Pneumatics is used in tyres, breaks, suspension speed control and time delay
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
