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?
Hydraulics is the use of liquids to transmit power. Pneumatics is the use of gases (usually air) to transmit power.
Hydraulic and Pneumatic systems are similar in that they both use double/single acting cylinders to operate something - Be it an automatic door for pneumatics and other such trivial tasks, or JCBs with hydraulics. Another key similarity would be the way in which they work - they both take the easiest path where available and both use 3/2 valves. A major difference between them is the pressures involved, the output forces and the use of 4/3 (hydraulics) and 5/2 (pneumatics) to operate a double acting cylinder.
Machines of all types need power. Power allows the machines to do specific kinds of work. Two of the most efficient and compact forms of power for machines are hydraulic and pneumatic systems. Hydraulics and pneumatics can be configured into different types of power sources to lift, lower, pull, push, turn, rotate and move machines carrying tremendous loads. Tools can also be powered to break stone, join steel and cut wood. Hydraulics and pneumatics provide the energy to make work happen.
One similarity is that they both use fluids. Both gasses and liquids are fluids. the two are also compressible.
In hydraulics. Power is transmitted through the air. The pneumatic. Power is transferred by the oil.
Hydraulics use liquids as the working fluid, pneumatics use gases as the working fluid.
Both pneumatics and hydraulics have their own advantages and disadvantages. Pneumatics are generally faster and more responsive, but hydraulics can handle higher loads and pressures. The choice between the two depends on the specific application requirements and constraints.
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.

BMW uses hydraulics for its brakes
One uses a liquid, one uses air. not the same
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
Basically pneumatics deal with lower loadings, hydraulics offer a better power to space ratio, useful in say aircraft design.
"in" and "out" are the direction of the pressure.
It is extremely essential in Hydraulics and mechanics. Your car would not run without pneumatics.
