Block 1

Pressure is expressed in units of...

source, medium & detector are three elements for the ...

a very thin layer of air lying over the surface of the wing

helicopters, movement around the longitudinal and lateral axes is handled by

Thrust is an example of Newton's __________ Law

An imaginary straight line running from the wing's leading edge to its trailing edge

Newton's first law is:

What stability would tend to bring the wing back to level flight

What in physics is the quantity which denotes both the speed of an object and the direction in which the object moves

what are the 3 methods of heat transfer

What stability will involve the time it takes the aircraft back to static stability

velocity of a fluid increases, the static pressure of that fluid will decrease is:

The actual amount of water vapor in a mixture of air & water is:

a lever with the resistance between the fulcrum and the effort is

what time is break

1 psi =

A lever with the fulcrum between the resistance and the effort

The ratio of the speed of an aircraft to the speed of sound is...

heat transferred by way of physical contact of two or more objects having different amounts of heat is:

What is the process by which heat is transferred by movement of a heated fluid?

Gauge pressure is

what is a device that creates a force based on Bernoullli's principles or newton's laws?

What stability would tend to pitch the nose of the aircraft up & down

Momentum is Newton's _________ Law

what has a purpose to create an aerodynamic force that keeps the flight control in a deflected position

The force that is equal to centripetal force, but acting in an opposite direction is called:

the force needed to move the flight controls can be excessive, what can be use to help move the flight controls

Helicopters with two main rotor at each end

An example of how the sun heats the earth is:

the formula for conversion from Celsius to Fahrenheit is

to change direction of force is the advantage of

helicopters, increasing lift on the back side of the main rotor

longitudinal, lateral and vertical axises intersect at this point

a lever with effort between the fulcrum and the resistance

Area is expressed in units of...

when air is flowing at subsonic speed, it acts like

Volume is expressed in units of

What is the purpose of flight controls

The initial response that an airplane displays after its equilibrium is disrupted

Force is expressed in units of...

(V_{1 x} P_{1) =} (V_{2 x} P₂) is the formula for _________ Law

pressure equal to gauge pressure plus atmosphere pressure is

The natural frequency at which the atoms within that matter vibrate is....

helicopters built in the USA, the main rotor, (view from the top down)

What form of energy is only produced by the conversion of one of the other form of energy

at supersonic flow, air acts like

semi- ridge rotor system use

absolute humidity is
