AFAB 115 Final Study Guide Questions
with 100% Correct Answers
What is ductility? - Answer-The property of a metal, which permits it to be permanently
drawn, bent, or twisted into various shape without breaking
What is the ability of a material to resist the forces that tend to damage it at the point of
applied load called? - Answer-bearing strength
What does a metal which can be hammered, rolled, or pressed, into various shapes
without cracking, breaking, or having some other detrimental effect have? - Answer-A
high malleability
What is brittleness? - Answer-The property of a metal, which allows little bending, or
deformation without shattering
What is the point at which load would cause an initial indication of a permanent
distortion called? - Answer-yield strength
True or false: Tensile strength is measured by the resistance of a material to a force
that would tend to pull it apart. - Answer-True
What does the aircraft structures basic construction consists of? - Answer-The fuselage,
wings, empennage, landing gear, and powerplants.
What should the bearing strength of the sheet metal and the shear strength of the rivet
be? - Answer-relatively equal
True or False: the shear strength of the rivet must be greater than the bearing strength
of the sheet metal - Answer-True
What are the parts of an aircraft structure designed to carry loads and or stresses
called? - Answer-structural members
What is a spar? - Answer-The wings principle structural member
What are the Ailerons, Rudder, and Elevator? - Answer-The three Primary flight Control
Surfaces of an aircraft
, What are the three secondary control surfaces? - Answer-The Slats, Spoilers, and
Flaps.
What are the purposes of Slats and Flaps? - Answer-To increase the camber of a wing,
and increase lift at slower speeds
What is the purpose of spoilers? - Answer-To slow the aircraft and disrupt the lift of an
airfoil.
What are structural supports that are under the aircraft skin? - Answer-Longerons,
bulkheads, and stringers
True or False: Longerons do not run the entire length of the aircraft fuselage. - Answer-
False.
(They do run the entire length)
What are are tension, compression, torsion, shear, and bending? - Answer-The five
major stresses that act on an aircraft
What is strength? - Answer-The ability of a material to withstand forces, which tend to
deform it in any direction, and the ability of that material to resist stress without breaking
What is shear strength? - Answer-The point at which a materials would fail under shear
force
True or false: The property of metal to return to its natural shape is called ductility. -
Answer-False
(It is called elasticity)
What is The outer covering of an aircraft called? - Answer-The skin
What is an example of the bearing strength of a joint being insufficient? - Answer-If a
bolt were installed in a hole that was too large, and the head was pulled through the
material when torque was applied
What is a non flammable, chromic acid based coating chemical? - Answer-Alodine 1201
What does Alodine 1201 produce? - Answer-A chrome conversion coating on aluminum
and its alloys
What color is applied Alodine? - Answer-gold or tan
What does Applied Alodine do? - Answer-It becomes part of the aluminum surface
