    • D.

      None of the Above

    Correct Answer
    A. Criteria
    Explanation
    Criteria refers to the desired specifications or elements that a product or system should have. It is a set of standards or requirements that need to be met in order for the product or system to be considered successful or effective. Criteria help to define the expectations and goals for the development or evaluation of a product or system, and they serve as a benchmark for determining its quality or performance.

    Rate this question:

  • 13. 

    Which step in the design process uses a design brief? Why?  

    • A.

      Define the Problem, because the problem is given to you by a client.

    • B.

      Develop Ideas, because it is what students do when they first see a design brief.

    • C.

      Research, because a design brief gives criteria to research.

    • D.

      Communicate Results, because design briefs deal with clients.

    Correct Answer
    A. Define the Problem, because the problem is given to you by a client.
    Explanation
    The correct answer is Define the Problem, because the problem is given to you by a client. In the design process, the first step is to clearly understand the problem or challenge that needs to be addressed. A design brief is a document that outlines the objectives, requirements, and constraints of a project, and it is typically provided by the client. By analyzing the design brief, designers can gain a clear understanding of the problem they need to solve and the goals they need to achieve. This step sets the foundation for the entire design process and ensures that the final solution meets the client's needs and expectations.

    Rate this question:

  • 14. 

    Which step in the design process uses a decision matrix? Why?  

    • A.

    • B.

      Design Brief, because that’s where you find a criteria to judge an idea.

    • C.

      Choose the Best Idea, because a decision matrix helps you make educated decisions.

    • D.

      All of the above.

    Correct Answer
    C. Choose the Best Idea, because a decision matrix helps you make educated decisions.
    Explanation
    The correct answer is "Choose the Best Idea, because a decision matrix helps you make educated decisions." In the design process, a decision matrix is used during the step of choosing the best idea. This is because a decision matrix provides a systematic way to evaluate and compare different ideas based on specific criteria. By using a decision matrix, designers can objectively analyze the strengths and weaknesses of each idea and make an informed decision on which idea is the most suitable for further development.

      Height and Width

    • C.

      Width and Depth

    • D.

      Depth and Width

    Correct Answer
    B. Height and Width
    Explanation
    The front view of a drawing shows an object's height and width. This view provides a two-dimensional representation of the object, displaying its vertical and horizontal dimensions. The height refers to the vertical measurement, while the width refers to the horizontal measurement. Together, these dimensions give a comprehensive understanding of the object's size and shape from the front perspective.

    Rate this question:

  • 17. 

    The right side view of a drawing shows an objects _______________.

    • A.

      Height and Depth

    • B.

      Height and Width

    • C.

      Width and Depth

    • D.

      Depth and Width

    Correct Answer
    A. Height and Depth
    Explanation
    The right side view of a drawing shows the height and depth of an object. This view provides a perspective of how tall and how deep the object is when viewed from the right side. It does not show the width of the object, as that would be visible in a different view.

    Rate this question:

  • 18. 

    Why is it important to follow the “rules” of sketching and dimensioning?  

    • A.

      If rules are followed engineers, designers, and manufacturers, can see the size, and location of all features.

    • B.

      If rules are followed engineers, designers, and manufacturers, understand the working drawing because all working drawings follow the same rules and language.

    • C.

      If rules are followed engineers, designers, and manufacturers, can see the size, and location of all features.

    • D.

      All of the above.

    Correct Answer
    D. All of the above.
    Explanation
    Following the "rules" of sketching and dimensioning is important because it allows engineers, designers, and manufacturers to accurately understand the size and location of all features in a working drawing. By following these rules, all working drawings will follow the same language and standards, making it easier for everyone involved to interpret and communicate the information effectively. Ultimately, adhering to these rules ensures consistency, clarity, and accuracy in the design and manufacturing process.

    Rate this question:

  • 19. 

    What is NOT an example of a geometric constraint?

    • A.

      Parallel lines

    • B.

      Horizontal and vertical lines

    • C.

      Isometric shapes

    • D.

      Perpendicular lines

    Correct Answer
    C. Isometric shapes
    Explanation
    Isometric shapes are not an example of a geometric constraint because they do not impose any restrictions or limitations on the shape or position of other objects. Geometric constraints are typically used to define relationships between different elements in a design, such as parallel or perpendicular lines, to ensure that they meet specific criteria. Isometric shapes, on the other hand, are a type of three-dimensional representation that maintains equal angles between the axes, but they do not impose any specific geometric relationships between objects.

    Rate this question:

  • 20. 

    Which is the correct order of steps for completing a final product?

    • A.

      Hand-drawn sketch, 3D Model, Working Drawing, Prototype

    • B.

      Hand-drawn sketch, Working drawing, Prototype, 3D Model

    • C.

      Hand-drawn sketch, Working drawing, 3D Model, Prototype

    • D.

      Prototype, Working drawing, Hand-drawn sketch, 3D Model

    Correct Answer
    A. Hand-drawn sketch, 3D Model, Working Drawing, Prototype
    Explanation
    The correct order of steps for completing a final product is to start with a hand-drawn sketch to visualize the concept, then create a 3D model to further refine the design, followed by creating a working drawing which includes all the necessary details and dimensions. Finally, a prototype is made to test and validate the design before mass production.
