- AA. Structural considerations
- BB. Aerodynamic considerations
- CC. A and B are true
- DD. A and B are false
3Q3. The failure of the Langley flight in 1903 was a consequence of

- CC. A wrong aerodynamic wing design
- DD. The interference between the front and rear wings
4Q4. The buckling is a phenomenon that appear in (i) structures subjected to (ii) loads
- AA. (i) wide (ii) tension
- BB. (i) wide (ii) compression
- CC. (i) thin (ii) tension
- DD. (i) thin (ii) compression
5Q1. What does the AXIAL STRESS consist on?
- Aa)It occurs when the aircraft is pressurised and the pressure hull lengthens.
- Bb)Stress raised in a container when it is filled, where the contents act to expand thecontainer.
- Cc)It occurs when an structure is subject to several different loads.
- Dd)It produces Stress Cracks due to tension and compression.
6Q2. The factor that doesn’t affect creep (elongation) is:
- Aa)Material type
- Bb)Temperature applied
- Cc)Duration of the load
- Dd)Type of object that produces it
7Q3. Which of the following events does not produce SHOCK LOADS?
- Aa)Bird strike directly on to the compressor blades of a jet engine
- Bb)Heavy landing
- Cc)Old rubber band stretches and then fails before the normal load is applied
- Dd)High intensity wind gust
8Q4. What is DESIGN LIMIT LOAD OR DLL
- Aa) This is the maximum load that the aircraft designer or component manufacturer expects the airframe or component to be subject to in operation.
- Bb) After the aircraft has been subject to this load, there may be permanent deformation of the aircraft’s structure, but it must not collapse.
- Cc) Is equal to the safety factor multiplied by 2
- Dd) Load which produces a catastrophic failure
9Q5. The Safe life is based on:
- Aa) Landings
- Bb) Pressurisation cycles
- Cc) Calendar time
- Dd) All the above
10Q6. About FAIL-SAFE STRUCTURE:
- Aa) Structure safe because one strong takes the entire load.
- Bb) Allows the structure to continue operating normally up to the static ultimate permanently.
- Cc) Damage would be found by luck because the structure does not show any problem.
- Dd) Extra structural items have a weight penalty, and this has led to a change toward designing damage-tolerant structures.
11Q7. DUL = Design Ultimate Load magnitude order in airplanes is:
- Aa) X4
- Bb) X5.5
- Cc) X10
- Dd) None of above
12Q.8 FRAME CONSTRUCTION in airplanes involves the use of mainly:
- Aa) SEMI-MONOCOQUE STRUCTURES

- Bb) It has a TOP Pressure Bulkhead
- Cc) The plane is completely pressurized to avoid internal forces
- Dd) The Pressure is different depending of the seat that you occupy
14Q.10.PASSENGER CABIN WINDOWS
- Aa) Are essential for temperature regulation
- Bb) The higher pressure of the outside can make them break in mid air
- Cc) Are non-FAIL-SAFE STRUCTURE
- Dd) Are points where the structure weakens

- Cc) Forward spar, main spar and auxiliary spar
- Dd) Front spar, forward spar and rear spar
21Q.17 The torsion box:
- Aa) Increases the rigidity of the wing and resists the twisting and bending motion
- Bb) Increases the mass of material used during the construction and due to this the weight is increased
