• A piece of paper

The jaws of an ant exert a pressure of 0.005 kPa.

• True

• False

Pascal's Law states that a fluid transmits pressure equally in all directions.

• True

• False

Hydraulic systems use natural gas as an enclosed fluid.

• True

• False

Pneumatic means it uses:

• Wood

• Gasoline

• Air

• Water

To find the pressure on an object you need to calculate:

• pressure = F/A

• pressure = A/F

• pressure = F x A

• pressure = A x F

A pneumatic system would be found in a dentist drill, air brakes of a big truck, jake hammer and paint sprayers.
