Quiz 1
The quiz is concerned with Chapter 1 - aircraft structure introduction and Chapter 2- airframe structure. There will be 25 questions picked in random order. Remember, you have to finish in 20 minutes.
Now, let's go!
The aircraft structure must remain substantially intact after experiencing:
the design ultimate load times a 1.5 factor of safety
the design limit load plus the design ultimate load
the design limit load times a 1.5 factor of safety
A fail safe structure:
is changed before its predicted life is reached
has redundant strenghth which will tolerate a certain amount of structural damage
is secondary structure of no structual significance
A safe life structure:
is changed before its predicted life is reached
should not fail until a predicted number of fatigue cycles has been achieved
will only fail after a known number of operations of hours of use
Of the airframe stresses, ( ) is a force which tends to shorten a structure.
Which design philosophy is applied for the following spar?
fail safe
damage tolerant
safe life
During testing, when a ( ) is applied to the structure, it must not suffer any permanent deformation.
Proof Load
Design Limit Load
Design Ultimate Load
The metal showed in the picture below suffered from:
oxidation corrosion
stress corrosion
electrochemicalcorrosion
