and become defects.
Nondestructive testing is often differentiated from other
measurements or inspection techniques in that: [ANS:] NDT
Guru01 - Stuvia
involves indirect tests related to some other quality or
characteristic of material.
What are the functions of NDT? [ANS:] Identifying and sorting of
material.
Identifying of material properties.
Ensuring absence of faults or defects that could cause a part to
fail.
An important basis for the success of fracture control design
procedures is: [ANS:] The need to ensure that unexpected flaws of
some critical size are not present when the component enters
service.
If properly used, NDT can assist in fracture control by: [ANS:]
Providing an accurate evaluation of the number and type of
discontinuities that exist in a material .

A statement that a particular experiment produced a 0.9
probability of detection with a 95% confidence level means that:
[ANS:] There is a 5% probability that the probability of detection is
overstated.
Most solid metals and plastics that have reasonable strength at
room temperature are called: [ANS:] Engineering materials.
Material properties, as used in design, are most frequently
determined by: [ANS:] Materials testing.

Even at the early stages of product planning, NDT should be
considered because: [ANS:] The design of the part should permit
easy access to critical areas for later inspection.

which of the following material properties are of most concern if
corrosion resistance is essential? [ANS:] Chemical properties.
Which of the following is true relative to the comparison of the
properties of aluminum-based alloys and iron-based alloys? [ANS:]
Iron can exist in several different crystalline structures and its
properties can be controlled by heat treatment.
Tensile test are conducted on specimens from a newly developed
alloy in order to determine the ultimate tensile strength of the
material. Such tests are referred to as: [ANS:] Destructive tests.
A bar that is 2 in. long, 2 in. wide and 1 in. thick is subjected to a
tensile load acting along the lenght of the bar of 36000 lbs. What is
the tensle stress within the bar? [ANS:] 18000 psi.
What is Point B on the Stress-Strain diagram where it first starts to
curve? [ANS:] Elastic limit.

Stress-Strain diagram, which of the following ranges indicates the
affect of work hardening, to its maximum, caused by plastic flow
of the material during a tensile load? [ANS:] Deformation rate to
the ultimate strength
On the Stress-Strain diagram, the points represented by E and F
would be closer together if the material being tested were: [ANS:]
Less ductile.
The modules of elasticity, or Young's modules, is related to the
material's relative: [ANS:] Stiffness and yield strength.

Which of the following materials is typically considered when the
application only requires high compressive strength? [ANS:] Cast
iron.

A fatigue failure can often be prevented by using NDT to: [ANS:]
Detect surface discontinuities that could be stress risers.
Which of the following tests uses a pendulum to break a specimen
that is notched and supported on both ends, with the results of
measuring energy absorption? [ANS:] Charpy test.
What is a S-N curve? [ANS:] An endurance limit curve diagram.
Direct hardness test provide a measure of a material's ability to
resist: [ANS:] Surface and near-surface penetration.
Under ordinary usage, metals exist as: [ANS:] Crystalline solids.
The term body-centered cubic BCC, face-centered cubic FCC
and hexagonal close-packed HCP all refer to the: [ANS:] Lattice
structures that make up unit cells in a solid metallic structure.
