PNEUMATICS AND HYDRAULICS

Hydraulic systems use ________ to transfer force from one point to another.

• Air

• Liquid

• Solid

• Gas

Pneumatics is concerned with a system that uses:

• Oil

• Expanded air

• Compressed air

• Electricity

Air is compressible and liquid is incompressible.

• True

• False

If an object is compressible it can be squeezed to fit into a smaller space than it normally does.

• True

• False

What is a hydraulic system?

• A system that uses a liquid under pressure to transmit a force to do work.

• A system that uses a gas under pressure to transmit a force to do work

• Pascal's law.

• It uses water to push an object.

Where can you look on your car to see a good example of a basic piston-driven hydraulic system?

• The power steering system

• The instrument panel

• The brake system

• The radio system

Which of the following sentence is true?

• Gases are easy to squish

• Liquids are easy to squish

What does Pascal's law state?

• When you apply a small amount of pressure to a compressed fluid, it will send that pressure nowhere.

• When you apply pressure to a confined fluid, the fluid will send that pressure out in all directions at the same rate.

• When you apply a large amount of pressure to an object, it will float.

• When you use a fluid to apply pressure, the pressure will release.

What is a pump?

• A fluid system that allows pressure to be applied to another object.

• Compressed air that pushes out pressure from an object.

• A mechanical device or part that is used to move a fluid through or into something.

• A mechanical device that does not move a fluid.

What is a valve?

• A mechanical device or part that moves a fluid through or into something.

• A system that allows a fluid to move quickly.

• A mechanical fluid system that releases pressure.

• A mechanical device or part that controls the flow of fluids.
