Non of the above
The basic idea behind any hydraulic system is very simple: Force that is applied at one point is tranitted to another point using________
A compressible fluid
An incompressible fluid
A cold compress
A hot compress
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?

A deli
A farm
Farmers market
A ________ is a sliding plug that fits closely inside the bore of a cylinder
A jack
A piston
A valve
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.
