The force that keeps an airplane in the air, generated by the wings.
What is lift
100
This plane became the first commercially successful jet airliner in the 1950s.
What is the Boeing 707?
100
The name of the original Boeing company founder.
Who is William (Bill) Boeing?
100
The torque-controlled fastener commonly used for primary joints in aircraft structures that requires precise installation and may use a shear-off head.
What is a Hi-Lok or Hi-Shear fastener (or torque-controlled bolt/sheer head fastener)?
100
The line along which bending moment is zero in a simply supported beam with a symmetric load.
What is the neutral axis?
200
This instrument shows an aircraft’s altitude above sea level.
What is the altimeter?
200
The aircraft that first demonstrated controlled, powered, heavier-than-air flight by humans.
What is the Wright Flyer?
200
The historic Boeing model that first used jet propulsion in a bomber role for the U.S. Air Force during the early Cold War and later inspired commercial designs.
What is the Boeing B-47 Stratojet?
200
The design practice of orienting plies at multiple angles (e.g., 0°, ±45°, 90°) with symmetry about a neutral plane.
What is quasi-isotropic layup (or balanced, symmetric layup)
200
The slope of the load-deflection curve at small strains for a linear elastic material, commonly denoted E.
What is Young’s modulus (elastic modulus)?
300
The angle between the wing chord line and the oncoming airflow, which dramatically affects lift.
What is angle of attack?
300
The record-breaking German rocket-powered research aircraft that first exceeded Mach 1 in a dive.
What is the Messerschmitt Me 163 Komet?
300
The major aerospace competitor Boeing merged with or acquired in 1997, a deal that reshaped the corporate product lineup.
What is McDonnell Douglas?
300
The joining method that forms a metallurgical bond between parts via heat, often used for high-strength, leak-tight assemblies.
What is welding?
300
The type of buckling that occurs when a slender column fails by lateral deflection under axial compression.
What is Euler buckling (or elastic buckling)?
400
v is the fluid flow speed, p is the static pressure, and ρ is fluid density.
What is Bernoulli's equation?
400
The iconic U.S. Navy fighter used extensively in the Pacific Theater in 1945, recognizable by its foldable wings for carrier storage.
What is the F6F Hellcat? F4U Corsair was land based and F4F was used earlier in the war.
400

What is Pacific Aero Products Co.
400
The UG NX command used to give a solid feature thickness by extending a sketch perpendicular to the sketch plane.
What is Extrude (or Pad)?
400
The structural analysis method that superposes effects of individual loads or load cases because the governing equations are linear.
What is the principle of superposition?
500
The navigation system that uses time difference of arrival from multiple ground stations to determine position (historically used before GPS).
What is LORAN?
500
The German World War I biplane widely credited with advancing fighter aircraft design; flown by pilots like the Red Baron.

The geometric property that strongly affects bending stiffness and stresses in a beam section, commonly denoted I.
What is the second moment of area (moment of inertia)?
500
The energy-based theorem stating that the work done by external forces equals the strain energy for conservative systems and used in virtual work formulations.
What is Castigliano’s theorem (or the principle of virtual work)?
