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.
What is one of the best places to get up close with the large hydraulic machines?
At the local mall
A deli
A construction site
Farmers market
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.
A hoist uses hydraulic pressure to lift a car.
True.
False.
