concerning hydraulic machines
gas are compressible, so the result wouldn't be good. (You can easily decrease the volume of the gas, the other side wont lift at all =[ )
whereas "ideal liquids" are assumed to be incompressible. Thats why hydraulic machine works.
Solid. If you have a giant piece of metal across the machine, of course it doesnt work, becuase when you apply force on one side, the force is as you are working on the center of mass.. so the other side wont go up.
