Fluid Technology Quiz

What does fluid technology combine?

• Mechanics with the omni-directional nature of fluids

• The study of gases only

• Hydraulic systems without mechanics

• Pneumatics without the use of liquids

What is controlling gases under pressure called?

• Pneumatics

• Hydraulics

• Mechanics

• Fluidics

How is pressure measured?

• Cubic feet per minute

• Liters per square meter

• Pounds per square inch

• Inches per square foot

What does Pascal's law state?

• Fluids compress under pressure

• The pressure at any point in a body of fluid is the same in every direction

• Pressure at any point in a body of fluid is different in every direction

• Pressure in a fluid acts upward only

What happens when force is applied to a piston in a hydraulic cylinder?

• The force is not transmitted to the other cylinder

• The force only acts on the piston it is applied to

• The force decreases due to friction

• The force is transmitted equally to the bottom cylinder

What can create efficiency-robbing molecular friction in hydraulic systems?

• Using a very short hose

• Using a hose of moderate length

• Using extremely small or long connecting hoses

• Using a rigid hose only

How can a hydraulic system create a mechanical advantage?

• By using gases instead of liquids

• By varying the size of the piston from one side of the system to the other

• By using the same size pistons on both sides

• By applying less force

What is the result if the larger cylinder’s piston surface is 5 times that of the smaller cylinder?

• The resulting force will be 10 times greater

• The resulting force will be 5 times greater

• The resulting force will be the same

• The resulting force will be 2 times greater

If 2 lbs. of force is applied to the input cylinder’s piston rod with an area of 1 in2, what is the force out if the output piston area is 5 in2?

• 5 lbs.

• 10 lbs.

• 20 lbs.

• 2 lbs.

Where are fluid technology principles applied?

• In backhoes, elevators, and liftgates

• Only in hydraulic presses

• Only in educational settings

• Exclusively in space technology
