Aerodynamics Test

Front

What is the main purpose of the vertical stabilizer on an aircraft?

Back

To control yaw.

Front

Which of the following best describes Bernoulli’s Principle?

Back

An increase in the speed of a fluid occurs simultaneously with a decrease in pressure.

Front

What property describes the tendency for an object to remain at rest or in constant motion until acted upon by unbalanced forces?

Back

Inertia.

Front

The weight of a car is 40,000N, what is the mass? (Remember, W=mg and g=10m/s²)

Back

4000kg.

Front

Which part of the aircraft is primarily responsible for controlling roll?

Back

Ailerons.

Front

Define lift in the context of aerodynamics.

Back

Lift is the force that directly opposes the weight of an aircraft and holds the aircraft in the air.

Front

What is drag in aerodynamics?

Back

Drag is the aerodynamic force that opposes an aircraft's motion through the air.

Front

Explain the concept of thrust in aviation.

Back

Thrust is the force that propels an aircraft forward, generated by engines.

Front

What is the role of the elevator in an aircraft?

Back

The elevator controls the pitch of the aircraft.

Front

Define the term 'aerodynamic efficiency.'

Back

Aerodynamic efficiency is a measure of how effectively an aircraft uses thrust to overcome drag.
