What are the two types of power that uses fluids.
Pneumatics and Hydrogen
Pneumatics and Horsepower
Pneumatics and Hydraulics
Pneumatics and Horoscops
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.
Which one of the following is an example of a hydraulically operated machine?
A wheel barrow
A laptop computer
A bulldozer
A vacuum cleaner
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
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 so that the pressure is the same throughout.
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.
How are a hydraulic system and a pneumatic system similar?
Both use a gas.
Both use water.
Both use a fluid to apply force.
Both use valves and pistons.
A bicycle pump is an example of a ______________________.
Valve.
Pneumatic system.
Hydraulic system.
Piston.
What is a pneumatics system compressing?
water
air or gas
oil
milk
Force is measure in Newtons.
True
False
Pascal's Law states that a fluid transmits pressure equally in all directions.
True
False
To find the pressure on an object you need to calculate:
pressure = F/A
pressure = A/F
pressure = F x A
pressure = A x F
If there is a leak in a hydraulic or pneumatic system, the pressure will increase.
True
False
If a hydraulic system has 1000 N applied to the input piston and has an area of 81 cm2, what is the pressure?
12.35 Pa
12,346 Pa
1235 Pa
123,457 Pa
The reason gases can be compressed is because:
The particles are very close together.
The particles are merely vibrating.
The particles are unable to move.
The particles are very far apart.
If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?
The pressure will increase
The pressure will decrease
The pressure will remain constant
The pressure will equalize
Gas pressure is caused by
Gas molecules heating up
Gas molecules reacting with other gas molecules
Gas molecules hitting the walls of a container
Gas molecules hitting other gas molecules
The pressure inside the syringe will decrease if we move the plunger in what way?
Direction A
Direction B
We don't have to move the plunger as the pressure will change on its own.
None of the above answers.
We can increase the pressure of a gas by:
Adding more gas.
Reduce the volume of the container.
Increase the temperature of the gas.
None of the above answers.
What is the Pa equivalent to?
Newtons
N/m2
nanometers
1,000,000
Newtons
