Hydraulics

A unit of pressure is called a

• bernoulli

• pascal

• pound

• meter

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

• Air

• Liquid

• Solid

• Gas

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 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.

It's important for a hydraulic system to contain what?

• Air bubbles

• No air bubbles

• Compressible fluid

• Compressible gas
