CIVE 2700 Quiz 2 (Lec 9 - 16) Questions Answered Correctly
Seasoning is the process of ... - Answers drying timber to equivalent moisture content (EMC)
What are the three corrosion resistant types of steel according to CSA classification? - Answers
Types R, A, AT
A measure of energy absorbed during the fracture of a specimen of standard dimensions and
geometry when subjected to very rapid (impact) loading. Charpy impact tests are used to
measure this parameter, which is important in assessing the ductile-to-brittle transition
behaviour of a material - Answers Impact Energy
The basic structural unit of a crystal structure. It is generally defined in terms of atom (or ion)
positions within a parallelepiped volume. - Answers Unit Cell
A linear crystalline defect associated with the lattice distortion produced in the vicinity of the
end of an half-plane of atoms within a crystal. - Answers Edge dislocation
Loose knots in timber can... - Answers decrease strength and stiffness of lumber
The valence electrons are the electrons in the nearest shell to a nucleus of an atom. True or
False? - Answers False.
The valence electrons are the electrons of the outer shell of the atom.
What are the charges of Blast Furnace in steel production? - Answers Iron ore, coke, and
limestone
FCC (Face Centred Cubic) structure has 1 whole atom in the centre of the unit cell. True or False.
- Answers False
BCC (Body centred cubic) structure has 1 whole atom in the centre of the unit cell.
FCC has an atom at each corner and at each face of the unit cell.
steel shear stirrups with the bent ends will be used in a beams of concrete structure in
Manitoba where the temperature can be as low as -40. What are the mechanical test have to be
performed on the rebars' martial to evaluate the suitability of the material for the specified
application? Choose three tests that are required and explain. - Answers Bend Test
- to determine whether the material will suffer from cracking due to bending and deformation
under tensile stresses
