Aerodynamics is concerned about the motion of a solid object in the air. Based on the understanding that solid objects move when acted upon by an external force, aerodynamic seeks to explain the forces that keep the object in motion against the force of gravity. Do you know this? Get tested now!

• 1.

Who was the first to carry out a project in aerodynamics?

• A.

Otto Loewi

• B.

Otto Lilienthal

• C.

Otto Gammali

• D.

Otto Lomania

B. Otto Lilienthal
Explanation
Otto Lilienthal was the first to carry out a project in aerodynamics. He was a German aviation pioneer who made significant contributions to the understanding of flight. Lilienthal conducted extensive experiments with gliders and developed a systematic approach to studying the principles of aerodynamics. His work laid the foundation for modern aviation and influenced future aviation pioneers such as the Wright brothers.

When was the first project based on  aerodynamics conducted?

• A.

1891

• B.

1893

• C.

1899

• D.

1892

A. 1891
Explanation
The correct answer is 1891. This was the year when the first project based on aerodynamics was conducted.

Which of these issues is not related to aerodynamics?

• A.

Compressible flow

• B.

Boundary layers

• C.

Corrosion

• D.

Turbulence

C. Corrosion
Explanation
Corrosion is not related to aerodynamics because it is the process of deterioration of a material due to chemical reactions with its environment, typically involving the presence of moisture or corrosive substances. Aerodynamics, on the other hand, is the study of how air moves around objects and the forces that act on those objects in motion through the air. Compressible flow, boundary layers, and turbulence are all concepts and phenomena directly related to the study of aerodynamics.

Which of these is not a fundamental part of aerodynamics?

• A.

Continuum

• B.

Drag

• C.

Fluid mechanics

• D.

C. Fluid mechanics
Explanation
Fluid mechanics is not a fundamental part of aerodynamics. Aerodynamics is the study of how air flows around objects, and it includes concepts such as drag, pressure gradient, and the continuum assumption. Fluid mechanics, on the other hand, is a broader field that encompasses the study of how fluids, including both liquids and gases, behave and interact with forces. While fluid mechanics is certainly relevant to aerodynamics, it is not specifically a fundamental part of it.

Who was the first person to develop a theory about air resistance?

• A.

John Orwell

• B.

Isaac Newton

• C.

Logan Luke

• D.

Micheal Watkins

B. Isaac Newton
Explanation
Isaac Newton is the correct answer because he was the first person to develop a theory about air resistance. Newton's laws of motion, specifically his second law, explain how air resistance affects the motion of objects. He described air resistance as a force that opposes the motion of an object through a fluid, such as air. Newton's work on air resistance was a significant contribution to the understanding of physics and the study of fluid dynamics.

B. 1726
Explanation
The first theory about air resistance was developed in 1726.

When was the Hydrodynamica phenomenon first described in aerodynamics?

• A.

1788

• B.

1738

• C.

1739

• D.

1718

B. 1738
Explanation
The correct answer is 1738. This is the year when the Hydrodynamica phenomenon was first described in aerodynamics.

• 8.

Which of these is not explained in hydrodynamica?  ​​​

• A.

Density

• B.

Pressure

• C.

Flow velocity

• D.

Motion

D. Motion
Explanation
Hydrodynamica is a book written by Daniel Bernoulli that explains the principles of fluid dynamics. It covers various concepts such as density, pressure, and flow velocity, but it does not specifically explain motion. Motion is a broader concept that involves the movement of objects or particles, which may be influenced by fluid dynamics but is not directly addressed in Hydrodynamica.

Rate this question:

• 9.

Which of these is not a way by which aerodynamics is used?

• A.

Empirical approximations

• B.

Wind tunnel experimentation

• C.

Mathematical analysis

• D.

Mechanical simulation

D. Mechanical simulation
Explanation
Mechanical simulation is not a way by which aerodynamics is used. Aerodynamics is the study of how air moves around objects and the forces that act on those objects. Empirical approximations, wind tunnel experimentation, and mathematical analysis are all methods used to study and understand aerodynamics. However, mechanical simulation, which involves using computer models to simulate airflow and analyze its effects on objects, is not mentioned as a way of using aerodynamics.

When was the principle of heavier-than-air flight first expressed?

• A.

1809

• B.

1804

• C.

1805

• D.

1817

B. 1804
Explanation
The correct answer is 1804. In 1804, Sir George Cayley, an English engineer and inventor, first expressed the principle of heavier-than-air flight. He published a paper titled "On Aerial Navigation" in which he outlined the basic principles of flight, including the concept of lift, drag, and the use of a separate propulsion system. Cayley's work laid the foundation for the development of modern aviation and his designs and theories greatly influenced the pioneers of flight in the years to come.
