Engineering quiz review - Fundamentals of Aerodynamics

What are the four forces that affect a planes flight?

• Lift, Weight, Thrust, and Water content

• Lift, Drag, Thrust, and Weight

• Lift, Drag, Thrust, and Mass

• Drag, Thrust, Weight, and Volume

What is the lift?

•  is a mechanical force generated by a solid object moving through a fluid (liquid or gas) and is created by the wings. The direction of the lift is perpendicular to the flight direction. The magnitude of the life depends on several factors including, the shape, size, wing type, and velocity of the aircraft.

•  is a mechanical force generated by the engine to move the aircraft through the air. The thrust is provided by the propulsion system. The magnitude of the thrust depends on many factors like the type of engine, the number of engines, and the throttle setting. 

• is a force created by the gravitational attraction(pull) of Earth. The magnitude of the weight depends on the mass of all the airplane's parts (deadweight) plus the amount of fuel, plus any payload (cargo) on board (people, baggage).

•  is a mechanical force generated by a solid object moving through a fluid (liquid or gas). The drag is created by the air resistance to aircraft motion. The magnitude of the drag depends on surface area, velocity, and air density (it is directly proportional to the other 3 forces). The drag is the undesired force that is created as a result of the lift.

What is Thrust?

• s a mechanical force generated by a solid object moving through a fluid (liquid or gas). The drag is created by the air resistance to aircraft motion. The magnitude of the drag depends on surface area, velocity, and air density (it is directly proportional to the other 3 forces). The drag is the undesired force that is created as a result of the lift.
