Questions and Answers
(2022/2023) (Verified Answers)
1. Fracture is a type of material failure. Of the following which is another
type of material failure✔✔✔ Permanent deformation.
2. Which of the following statements best differentiates between a defect
and a discontinuity✔✔✔ Discontinuities can propagate and become
defects.
3. Nondestructive testing is often differentiated from other measurements
or inspection techniques in that✔✔✔ NDT involves indirect tests related
to some other quality or characteristic of material.
4. What are the functions of NDT✔✔✔ Identifying and sorting of
material. Identifying of material properties.
Ensuring absence of faults or defects that could cause a part to fail.
,5. An important basis for the success of fracture control design
procedures is✔✔✔ The need to ensure that unexpected flaws of some
critical size are not present when the component enters service.
6. If properly used, NDT can assist in fracture control by✔✔✔ Providing an
accu- rate evaluation of the number and type of discontinuities that
exist in a material .
7. A statement that a particular experiment produced a 0.9 probability of
detection with a 95% confidence level means that✔✔✔ There is a 5%
probability that the probability of detection is overstated.
8. Most solid metals and plastics that have reasonable strength at
room temperature are called✔✔✔ Engineering materials.
9. Material properties, as used in design, are most frequently
determined by✔✔✔ Materials testing.
10.Even at the early stages of product planning, NDT should be
considered because✔✔✔ The design of the part should permit easy
access to critical areas for later inspection.
, 11.which of the following material properties are of most concern if
corro- sion resistance is essential✔✔✔ Chemical properties.
12.Which of the following is true relative to the comparison of the
properties of aluminum-based alloys and iron-based alloys✔✔✔ Iron can
exist in several dif- ferent crystalline structures and its properties can
be controlled by heat treatment.
13.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✔✔✔ Destructive tests.
