SaSn00424 1.Define hydraulic ? Hydraulic is the study of pressure in liquids. 2.Define pnumatic. The study on pressure in gasses. 3.What are 4 hydraulic devices? • Excavator • Hydraulic hot molding press • H frame hydraulic press • Hydraulic Auto Indexer machine Sander Drill 4.What are 4 pneumatic devices? • Drill • grinder • sander • wrench

5. How do hydraulic systems work? The Force that is applied at one point is transmitted to another point using an incompressible fluid. 6.How do pnumatic systems work? A pneumatic system is any system that uses air pressure to move either a turbine or a cylinder to accomplish some work.

7.What are the major differences between hydraulic and pneumatic systems? a) Pneumatic systems use compressed gas such as air or nitrogen to perform work processes. b) Hydraulic systems use liquids such as oil and water to perform work processes.
