Perguntas do quiz (20)
11) The main components of an aircraft are:
(pg1)- Aa) Fuselage, wing(s), stabilishing surfaces, landing gear and flying control surfaces.
- Bb) Fuselage, wing(s), cockpit and flying control surfaces.
- Cc) Wing(s), stabilishing surfaces, engine(s) and flying control surfaces.
- Dd) Compressor, turbines, nozzle and combustion chamber.
22) How did aviation start?
pg1- AWith aircraft made up of mainly one wing, materials that were used were strong enough to bear the lift charge.
- BWith 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.
- CBy using semi-monocoque structures.
- DNone of the above
33) What are the main components of the semi-monocoque structures?
pg1- Aa) Frames, longerons, stringers and formers
- Bb) Frames, longerons and ribs
- Cc) Skin, floor, squares and panels
- Dd) All of the above
44) Mark the correct answer:
pg1- Aa) Frames make stronger the fuselage and spread the load
- Bb) Longerons give longitudinal strength to the wing
- Cc) Formers normally reinforce the shell structure when needed
- Dd) All of the above are correct
51) A classification of loads could be:
pg1- Aa) Ground and inertial loads
- Bb) Lift and drag
- Cc) Ground and air loads.
- Dd) Air and gusts loads.
62) Kinds of air loads:
pg2- Aa) Aerodynamic forces, acceleration, pressurization and weight.
- Bb) Aerodynamic forces, acceleration, inertia and gusts.
- Cc) Acceleration, inertia, weight and taxiing.
- Dd) Aerodynamic forces, acceleration, inertia and pressurization.
73) The load factor is:
pg2- Aa) The ratio between lift and weight of the aircraft.
- Bb) Lower in turnings.
- Cc) The ratio between weight of the aircraft and lift.
- Dd) The ratio between lift and weight of the wings.
84) Choose the best answer:
- Aa) DLL is the load for structural failure.
- Bb) Safety factor is 1.5 for aviation.
- Cc) DLL= Safety factor x DUL
- Dd) All are wrong.
95) Choose the wrong answer:
pg2- Aa) Safety factor is greatest in construction.
- Bb) Safety factor is 1.5 for aviation.
- Cc) Greater safety factor implies less weight.
- Dd) All are correct.
106) Referring to aeroelastic loads:
pg2- Aa) The aircraft is a rigid body.
- Bb) Aileron reverse causes break of wings.
- Cc) Flutter is caused of self-sustained oscillation.
- Dd) Wing divergence caused loss of control.
117) Landing gear loads exists on:
- Aa) Initial contact loads.
- Bb) Taxiing.
- Cc) Retracting loads.
- Dd) All of them.
128) Shock loads:
pg2- Aa) Consist of bird strikes and heavy landings.
- Bb) Bird strikes are so important in civil aviation.
- Cc) They can’t break the structure.
- Dd) They can’t generate permanent deformation.
139) Are fatigue loads lower than the design loads?
pg3- Aa) Yes
- Bb) No
- Cc) It depends
- Dd) They are mainly the same
1410) Fatigue loads are:
pg3- Aa) Cyclic load and they are less or the same than the last load
- Bb) Linear and independent of the last load
- Cc) Linear and higher than the last load
- Dd) Cyclic load and independent of the last load
1511) The damage caused by the fatigue is:
pg3- Aa) Inversely proportional to the fatigue load
- Bb) Acumulative
- Cc) Less as more times it is applied
- Dd) Independent of the load
1612) Are the elements with some perforations more or less favorable of getting loads concentration points?
pg3- Aa) More
- Bb) Less
- Cc) It depends on the type of perforation
- Dd) It is independent of the fact that the element is perforated or not
1713) Mark the factor which does NOT affect the fatigue:
pg3- Aa) Temperature
- Bb) Material
- Cc) Corrosion
- Dd) Size
1814) The estructure clasification is done by:
pg3- Aa) Material only
- Bb) Load and the grade of structure failure
- Cc) Temperature holding and material
- Dd) One of them is size
1915) One of the fail-safe structures is:
pg4- Aa) Landing Gear
- Bb) Flaps
- Cc) Wing skins
- Dd) Wing-fuselage joints
2016) One of the most used material in the current aviation is:
- Aa) Iron alloys
- Bb) Titanium alloys
- Cc) Mercury
- Dd) PVC
