Question 1

Have you ever taken a small piece of plastic or metal and bent it back and forth until it broke? If you have,you have performed a(n)____ test.
A) Young
B) failure
C) fatigue
D) tensile

Accepted Answer

Fatigue tests involve subjecting a material to repeated loading and unloading cycles, which can cause failure due to the accumulation of small cracks or damage. Bending a material back and forth until it breaks is an example of a fatigue test. The other options (Young, failure, and tensile) refer to different types of mechanical tests that do not involve repeated loading cycles.

Question 2

If you keep stretching a material it will eventually get to a point where it will no longer return to its original shape when the tension is released.This stage is called the ____ limit.
A) ultimate
B) tensile
C) failure
D) elastic

Accepted Answer

The elastic limit is the point beyond which a material will not return to its original shape after the tension is released, indicating the transition from elastic deformation to plastic deformation.

Question 3

____________________ cost is the total cost of a product that includes the amount spent on energy to run it.

Accepted Answer

Life-cycle
Life cycle

Question 4

One well-known product testing organization is ____ Laboratories (UL).
A) Utah
B) Underwriters
C) United
D) Unlimited

Accepted Answer

Underwriters Laboratories, commonly known as UL, is a well-known product testing organization that provides safety-related certification, testing, and inspection services.

Question 5

Test results most often take the form of descriptions.

Accepted Answer

Test results typically take the form of quantitative data or scores, rather than descriptions, to objectively measure performance or outcomes.

Question 6

____________________ is the change in length of the material that is under stress.

Accepted Answer

The answer of ____________________ is the change in length of...

Question 7

____ are opinions of those who have tried your product and will endorse it.
A) Descriptions
B) Analyses
C) Evaluations
D) Testimonials

Accepted Answer

Testimonials are statements or endorsements from people who have tried a product and are satisfied with it. They are an important form of social proof and can help to build trust and credibility with potential customers.

Question 8

____ refers to the pleasurable response you get to an object or experience.
A) Ergonomics
B) Aesthetics
C) Impact
D) Yield

Accepted Answer

Aesthetics refers to the beauty or attractiveness of an object or experience, which can lead to a pleasurable response from the individual.

Question 9

When a material stretches (strains)proportionally to the amount of force (stress),that material conforms to Hooke's law.

Accepted Answer

Hooke's law describes the relationship between stress and strain in a material that behaves elastically, meaning that it returns to its original shape after the stress is removed. The law states that stress is proportional to strain, and this relationship is observed in many materials, such as steel, rubber, and some plastics. Therefore, when a material stretches proportionally to the amount of force applied to it, it conforms to Hooke's law.

Question 10

A standard measurement of hardness is the ____________________ hardness test.

Accepted Answer

The answer of A standard measurement of hardness is the...

Question 11

Hardness is indicated by a letter: R,L,M,E,and K.

Accepted Answer

This is true, hardness can be indicated by different scales such as the Rockwell (R), Brinell (B), Vickers (V), Mohs (M), Shore (S), and others, but R, L, M, E, and K are indeed among them.

Question 12

In your evaluation,you must only look at your own role in the designing and making of the solution.

Accepted Answer

Evaluation should consider multiple perspectives, including the end-users, stakeholders, and broader impacts, not just the designer's role.

Question 13

Engineering testing is only performed on the product or system as a whole once its components are assembled.

Accepted Answer

Engineering testing is also performed on individual components and sub-assemblies before they are assembled into the final product or system. This ensures that each component meets the required specifications and can function properly within the larger system.

Question 14

The criteria of good design are ____.
A) immune to compromise
B) all based on aesthetics
C) all interrelated
D) entirely separable

Accepted Answer

The criteria of good design are all interrelated, meaning that they are dependent on one another and cannot be considered in isolation. Aesthetics may be a part of good design, but there are other criteria such as functionality, usability, sustainability, and innovation that are equally important. Good design also involves making compromises and balancing different priorities to create a successful product or solution. Therefore, choices A and B are incorrect, and D is not applicable as the criteria are not entirely separable.

Question 15

____________________,or "human factors engineering," has to do with designing products and environments that work well with people.

Accepted Answer

The answer of ____________________,or "human factors engineering," has to do...

Question 16

The modulus of elasticity is also called ____ modulus.
A) Newton's
B) Young's
C) Hooke's
D) Rockwell's

Accepted Answer

The modulus of elasticity is commonly known as Young's modulus, named after the British scientist Thomas Young, who first introduced the concept in 1807. Hooke's modulus is used to describe the elasticity of materials exhibiting Hookean behavior (linear elasticity), while Newton's modulus and Rockwell's modulus are not widely used terms in materials science.

Question 17

The failure point is also known as the ____ point.
A) rupture
B) strain
C) stress
D) yield

Accepted Answer

The failure point is commonly referred to as the rupture point, where a material breaks or fails under stress.

Question 18

____ is the force applied to a material.
A) Stress
B) Strain
C) Failure
D) Yield

Accepted Answer

Stress is the force applied to a material, typically measured in units of force per unit area. Strain is the resulting deformation or change in shape of the material in response to stress. Failure is the point at which the material can no longer bear the applied stress without permanent deformation or fracture. Yield is the point at which the material begins to deform plastically, meaning it will not return to its original shape after the stress is removed.

Question 19

____ refers to whether the product does what it is supposed to do.
A) Life-cycle
B) Aesthetics
C) Performance
D) Durability

Accepted Answer

Performance refers to whether the product is able to meet the intended requirements and fulfill its purpose. Aesthetics refer to the appearance or visual design of the product, durability refers to how long the product lasts, and life-cycle refers to the various stages a product goes through from production to disposal.

Question 20

The maximum force a material can withstand is called its ____________________ strength.

Accepted Answer

The answer of The maximum force a material can withstand...
