This & That
100
What makes something a fluid.
What is flow?
100
This is a picture of this machine & the Principle that allows this to happen.
What are hydraulic lift caused by Pascal's Principle that states pressure is transferred equally throughout a fluid in all directions.
100
The upward force exerted by a fluid.
What is buoyant force?
100
The name of this shape and how it works.
What is an airfoil which forces air to move faster over the top, creating low pressure, and slower across the bottom, creating high pressure, causing lift?
100
The force that must be greater than weight for an airplane to fly.
What is lift?
200
The state of matter that doesn't flow.
What is solid?
200
Boats float in water and blimps float in air because of this principle.
What is Archimedes Principle?
200
The object sinks.
What happens when an object's mass is greater than buoyant force.
200
The force that pushes the airfoil forward and the force that opposes it.
What is thrust & drag?
200
The force that should be increased during level flight for the aircraft to go faster.
What is thrust?
300
The difference in shape & volume between solids, liquids, & gasses.
What is solids have definite shape & volume, liquids have indefinite shape but definite volume, & gasses have indefinite shape & volume?
300
This principle defies gravity and makes plumbing possible.
What is Bernoulli's Principle?
300
The object floats.
When an object's mass equals buoyant force.
300
The force that causes the airplane into the sky, and the force that opposes it.
What is lift and weight?
300
The direction a cargo plane will move after releasing a large crate to parachute to the ground.
What is up?
400
The states of matter that have the strongest attractive forces between molecules & weakest.
What are solids & gasses?
400
The definition of Bernoulli's Principle.
What is pressure decreases as fluid speeds up?
400
The object rises.
When the object's mass is less that buoyant force.
400
The law that explains how the air comes down off the back of the airfoil and it pushes the airfoil up.
What is Newton's Third Law of action & reaction?
400
Draw a hydraulic system.
500
The states of matter that take the shape and volume of its container, and take the shape but not the volume of it's container.
What are gasses & liquids?
500
The definition of Archimedes Principle.
What is a submerged object is pushed upward by a force equal to the weight of the fluid it displaces?
500
I sink when floating on my back, but rise when I take a deep breath.
When I float, my mass is greater than buoyant force, but when I take a deep breath, my lungs & stomach expand increasing the volume of fluid I displace (buoyancy) until it's greater than my mass.
500
How a helicopter lifts off the ground.
What is, the airfoil shaped blades spin forcing air over the airfoils & creating lift.
500
How a spoiler works on the back of a race car.
What is the upside down airfoil creates low pressure under the spoiler and high pressure above the spoiler, pressing the car down to the track and increasing maneuverability?
