AEROSPACE MATERIALS 2026/2027 QUESTIONS AND
SOLUTIONS RATED A+
✔✔ The main or central structure of a heavier-than-air aircraft, typically streamlined,
which carries the crew and passengers and to which the wings are attached -
✔✔Fuselage
✔✔A principal span-wise structural member of a wing or other airfoil - ✔✔Spar
✔✔A principal longitudinal (fore and aft) member of the framing of an airplane fuselage,
usually continuous across a number of points of support. - ✔✔Longeron
✔✔A supporting brace that bears compression loads, tension loads, or both, as in a
fuselage between the longerons or in a landing gear to transmit the airplane. - ✔✔Strut
✔✔A longitudinal member installed between fuselage frames and former to give support
and strength to the skin. - ✔✔Stringer
✔✔A chordwise member used to give the wing its shape and to transmit the load from
the fabric or other covering to the spar - ✔✔Rib
✔✔A beam or member supported at or near one end only, without external bracing. -
✔✔Cantilever
✔✔An assemblage of members forming a rigid framework, which may consist of bars,
beams, rods, tubes, or wires. - ✔✔Truss
✔✔A structure that contains no internal members. - ✔✔Monococque
✔✔A structure that consists of a framework of vertical and longitudinal members
covered with a structural skin that carries a large percentage of the imposed stress. -
✔✔Semi-Monococque
✔✔Possibly, the most successful aircraft ever produced. The first airliner that gave the
airlines the ability to make a profit without relying on government mail subsidies. -
✔✔DC-3
✔✔One of the most famous early stressed skin aircraft constructed by Lockheed Martin.
This aircraft design proved to have a big increase in performance over its
contemporaries and rapidly became a favorite of early aviators. Lockheed used wood as
the structural material on the early models but later began to use aluminum. -
✔✔Lockheed Vega
, ✔✔The first jet transport that was also pressurized for high altitude flight. The original
design experienced a couple of in-flight failures due to metal fatigue. - ✔✔Comet
✔✔A vertical structural member that carries major structural loads in the fuselage and is
oriented perpendicular to the longitudinal axis. This term is also used to describe walls
or partial walls that separate fuselage compartments from one another. - ✔✔Bulkhead
✔✔An airplane with only one wing - ✔✔Monoplane
✔✔An airplane with two wings mounted one above the other - ✔✔Biplane
✔✔A non-structural part attached to a truss structure to streamline the shape. This
piece is oriented perpendicular to the longitudinal axis. - ✔✔Former
✔✔What type of aircraft construction did the Wright "R" of 1910 use? - ✔✔Truss or Box-
Type structure
✔✔An internal force that resists deformation of a body caused by the imposition of an
external load. - ✔✔Stress
✔✔The property of a solid body whereby it undergoes a permanent change in shape
when the yield point is exceeded. - ✔✔Plasticity
✔✔This type of stress is applied to a body when it is twisted. The stresses set up by the
force applied are actually shear stresses caused by a combination of internal tension
and compression. When a body is twisted, tension is created which operates diagonally
across the body. At right angles to the tension stress is a comprehensive stress. The
combination of these two stresses is known as this type of stress. - ✔✔Torsion
✔✔This term is used to describe the point where material becomes permanently
deformed. When a material is stressed beyond this point, the elastic limit has been
exceeded and it will no longer return to its original shape. - ✔✔Yield Point
✔✔This term is used to the describe the most stress that can be applied to a member
before it will fracture or break - ✔✔Ultimate Strength
✔✔The property of a material to fracture without changing shape. - ✔✔Brittleness
✔✔The property of a material to resist abrasion, penetration, or permanent deformation.
- ✔✔Hardness
