Define hydraulic. Hydraulic is the study of pressure in liquid.

Define pneumatic. Pneumatic is the study of pressure in gases.

What are 4 hydraulic devices? Four hydraulic devices are: cannons, switches, pumps, and bulldozers.

What are 4 pneumatic devices? Four pneumatic devices are: tire pumps, vacuums, rock drill, and cylinder.

How do hydraulic systems work? Moving fluids transfers power. pressure on fluids transfer force.

How do pneumatic systems work? A pneumatic system works by using air pressure to move something. The air is compressed and enters a cylinder, the cylinder has a rod attached to it. The air must leave the cylinder through a smaller hole. For example, the bicycle tire pumps air into the tire as you push the handle. The air inside the pump is then compressed and forced to leave through a smaller hole, which will then enter the tire.

What are the major differences between hydraulic and pneumatic systems? A couple major diffrences between pneumatic and hydraulic systems are: pneumatic systems use compressed like air or nitrogen to dowork, hydraulic systems use liquids like water and oil to do work. Pneumatic systems are open systems, exhausting the compressed air to atmosphere after use, hydraulic systems are closed systems, recirculating the oil or water after use.

These are some pneumatic tools.
