Which of these scientists was not involved in modern aeronautics?
- A.
  
  George Cayley
- B.
  
  Roger Bacon
- C.
  
  Leonardo da Vinci
- D.
  
  Albert Einstein
Correct Answer
D. Albert Einstein

Explanation
Albert Einstein was not involved in modern aeronautics. While he made significant contributions to the field of physics, including the theory of relativity, his work did not directly relate to the development of aircraft or aeronautical engineering. On the other hand, George Cayley is known as the "father of modern aeronautics" for his pioneering work in aerodynamics and aircraft design. Roger Bacon and Leonardo da Vinci also made important contributions to the study of flight and aeronautics.

Who is the founder of modern aeronautics?
- A.
  
  Leonardo da Vinci
- B.
  
  George Cayley
- C.
  
  Galili Galileo
- D.
  
  Isaac Newton
Correct Answer
B. George Cayley

Explanation
George Cayley is considered the founder of modern aeronautics because he made significant contributions to the field. He designed and built the first successful human-carrying glider, which demonstrated the principles of flight and paved the way for future developments in aviation. Cayley also proposed the concept of a fixed-wing aircraft, invented the modern aerofoil, and conducted extensive research on aerodynamics. His work laid the foundation for the development of airplanes and influenced many subsequent aviators and engineers in the field of aeronautics.

  7
Correct Answer
A. 3

Explanation
Aeronautics is the study and practice of designing, building, and operating aircraft. The main branches of aeronautics include aerodynamics, which deals with the motion of air and how it interacts with aircraft; aircraft structures, which focuses on the design and construction of aircraft components; and propulsion, which involves the study of engines and their performance. These three branches form the foundation of aeronautical engineering and are essential for the development and advancement of aircraft technology.

Which of these is the practice of aeronautics?
- A.
  
  Aeronautical engineering
- B.
  
  Aviation
- C.
  
  Aerospace engineering
- D.
  
  Aeronautical science
Correct Answer
C. Aerospace engineering

Explanation
Aerospace engineering is the practice of aeronautics as it involves the design, development, and construction of aircraft and spacecraft. It encompasses both aeronautical engineering, which focuses on aircraft, and astronautical engineering, which focuses on spacecraft. This field combines principles of physics, mathematics, and engineering to create and improve aircraft and spacecraft for various applications, such as commercial aviation, military defense, and space exploration.

8.

Which of these scientific laws is applicable in aeronautical science?
- A.
  
  Newton's law of motion
- B.
  
  Hooke's law
- C.
  
  Ohm's law
- D.
  
  Achimedes' law
Correct Answer
A. Newton's law of motion

Explanation
Newton's law of motion is applicable in aeronautical science. This law states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and direction, unless acted upon by an external force. In aeronautical science, this law is important for understanding the motion of aircraft, including the forces acting on them such as lift, drag, and thrust. Newton's laws also help in designing and analyzing the performance of aircraft, as well as predicting their behavior in different flight conditions.

Which of the following is NOT a primary control surface on an aircraft?
- A.
  
  Aileron
- B.
  
  Elevator
- C.
  
  Rudder
- D.
  
  Spoiler
Correct Answer
D. Spoiler

Explanation
Primary control surfaces are used to control the roll, pitch, and yaw of an aircraft. Ailerons control roll (movement around the longitudinal axis), elevators control pitch (movement around the lateral axis), and the rudder controls yaw (movement around the vertical axis). Spoilers are secondary control surfaces primarily used to disrupt airflow over the wing, increasing drag and decreasing lift.

Which of these forces does not act on spacecraft?
- A.
  
  Propulsive force
- B.
  
  Centrifugal force
- C.
  
  Gravitational force
- D.
  
  Aerodynamic lift and drag
Correct Answer
B. Centrifugal force

Explanation
Centrifugal force does not act on spacecraft. Centrifugal force is an apparent force that is experienced in a rotating frame of reference. It is the force that pushes objects away from the center of rotation. However, in the context of spacecraft, they operate in the vacuum of space where there is no air or atmosphere to create a rotating frame of reference. Therefore, centrifugal force does not come into play in the motion of spacecraft.
