1. Which material property best describes a material’s resistance to
deformation under load?
A. Elasticity
B. Strength
C. Hardness
D. Conductivity
Answer: B
Strength refers to a material’s ability to withstand applied loads
without failure or permanent deformation, making it a core
consideration in airframe structural design.
2. What is the primary function of the airframe structure?
A. Generate thrust
B. Provide lift
C. Support and distribute loads
D. Control fuel combustion
Answer: C
The airframe’s main role is to support all aerodynamic, structural,
, and system loads while maintaining aircraft shape and integrity
during operation.
3. Which type of stress causes a material to stretch or elongate?
A. Compression
B. Shear
C. Tension
D. Torsion
Answer: C
Tension is a pulling force that elongates a material by acting along its
length, commonly experienced in cables and structural members.
4. What is the main purpose of aircraft ribs in wing construction?
A. Increase engine thrust
B. Maintain airfoil shape
C. Reduce fuel consumption
D. Control hydraulic pressure
Answer: B
Ribs maintain the aerodynamic shape of the wing and help transfer
loads from the skin to the spars.
5. Which component carries the primary bending loads of a wing?
A. Stringer
B. Rib
C. Spar
D. Skin
Answer: C
Spars are the main structural members that resist bending forces
acting on the wing during flight.
6. What is the function of stringers in aircraft structures?
A. Absorb hydraulic pressure
B. Reinforce skin against buckling
, C. Generate lift
D. Control yaw
Answer: B
Stringers provide longitudinal reinforcement to prevent skin buckling
under compressive loads.
7. Which rivet type is most commonly used for high-strength structural
applications?
A. Blind rivet
B. Solid shank rivet
C. Split rivet
D. Plastic rivet
Answer: B
Solid shank rivets provide maximum strength and are widely used in
critical structural areas of aircraft.
8. What is the purpose of a countersunk rivet installation?
A. Increase aerodynamic drag
B. Reduce weight only
C. Provide a flush surface
D. Improve electrical conductivity
Answer: C
Countersunk rivets create a smooth aerodynamic surface by sitting
flush with the aircraft skin.
9. What is the main purpose of aircraft skin?
A. Store fuel
B. Provide aerodynamic contour and carry loads
C. Generate thrust
D. Control hydraulics
Answer: B
