Question 1
Question
1) The main components of an aircraft are:
(pg1)
Answer
-
a) Fuselage, wing(s), stabilishing surfaces, landing gear and flying control surfaces.
-
b) Fuselage, wing(s), cockpit and flying control surfaces.
-
c) Wing(s), stabilishing surfaces, engine(s) and flying control surfaces.
-
d) Compressor, turbines, nozzle and combustion chamber.
Question 2
Question
2) How did aviation start?
pg1
Answer
-
With aircraft made up of mainly one wing, materials that were used were strong enough to bear the lift charge.
-
With aircraft made up of two wings in order to distribute the lift charge, inasmuch as materials that were used were not strong enough to bear the charge in only one wing.
-
By using semi-monocoque structures.
-
None of the above
Question 3
Question
3) What are the main components of the semi-monocoque structures?
pg1
Answer

a) Frames, longerons, stringers and formers
-
b) Frames, longerons and ribs
-
c) Skin, floor, squares and panels
-
d) All of the above
Question 4
Question
4) Mark the correct answer:
pg1
Answer
-
a) Frames make stronger the fuselage and spread the load
-
b) Longerons give longitudinal strength to the wing
-
c) Formers normally reinforce the shell structure when needed

Question 6
Question
2) Kinds of air loads:
pg2

Question
5) Choose the wrong answer:
pg2
Answer
-
a) Safety factor is greatest in construction.
-
b) Safety factor is 1.5 for aviation.
-
c) Greater safety factor implies less weight.
-
d) All are correct.
