Day 8 Outside Work: Structural Fasteners Flashcards
Why should countersunk rivets be avoided in areas where aerodynamic smoothness is not a priority?
They are weaker in tension.
What is the significance of the ‘T7351 temper’ for Alloy 7075?
Enhances corrosion resistance
Which rivet material is primarily used for high-strength applications and can handle elevated temperatures without losing integrity?
Alloy 2219
What is a crucial factor in selecting a rivet for repairing an aircraft structure?
Compatibility of the rivet material with the material being riveted
Which factor is not considered when determining the edge distance for rivet installation?
Color of the material
What defines the ‘universal head’ rivet among other rivet types?
Its versatility in use where protruding head has no aerodynamic significance
Why is Alloy 3003 preferred over 1100 for certain applications, despite their similarities?
Higher strength and hardness
When using a countersink for rivet installation, what angle is typically used for creating a flush surface on high-speed aircraft?
100°
The solid shank rivet is commonly used in aircraft construction. What is a major disadvantage of this type of rivet?
Low tensile strength relative to shear strength
What is the primary use of Alloy 2024 in aircraft?
Airfoil and fuselage skins
Which aluminum alloy is described as having good workability, very good corrosion resistance, high fatigue strength, weldability, and moderate static strength?
Alloy 5052
Which of the following is a primary consideration when choosing a bucking bar for rivet installation?
Weight
In terms of rivet installation, what does the term ‘grip length’ refer to?
The combined thickness of the materials being joined
Alloy 7075 is noted for its strength. What is a drawback of using the T6 temper of this alloy?
Poor corrosion resistance
For rivet head identification, what does the prefix ‘MS’ signify?
Military Standard
