    What needs to be considered when designing the controls of a car?I. Psychological factorsII. Physiological factorsIII. Anthropometric factors

    • I only

    • II only

    • III only

    • I, II and III

    Correct Answer
    A. I, II and III
    Explanation
    When designing the controls of a car, it is important to consider psychological factors, such as the cognitive abilities and mental workload of the driver. Physiological factors, such as the physical capabilities and limitations of the driver, should also be taken into account. Additionally, anthropometric factors, which include the body dimensions and proportions of the driver, are crucial to ensure comfortable and ergonomic control placement. Therefore, all three factors - psychological, physiological, and anthropometric - need to be considered when designing car controls.

    What type of drawing is shown in the diagram?

    • Exploded isometric

    • Perspective

    • Orthographic

    • Isometric

    Correct Answer
    A. Exploded isometric
    Explanation
    The diagram in question shows a drawing that combines elements of both isometric and exploded views. In an exploded isometric drawing, the components of an object are shown separated from each other to illustrate their individual parts and how they fit together. This type of drawing is commonly used in technical and engineering fields to provide a clear understanding of the assembly process.

    Which statement does not describe an advantage of using computer aided design (CAD)?

    • Ability to interface with other computerised systems

    • Low capital cost

    • Ease of storage for designs

    • Reduction in time taken to update engineering drawings

    Correct Answer
    A. Low capital cost
    Explanation
    The statement "low capital cost" does not describe an advantage of using computer-aided design (CAD). CAD software typically requires a significant investment in terms of purchasing licenses, training, and hardware requirements. While CAD can bring cost savings in the long run by reducing the need for physical prototypes and improving efficiency, the initial capital cost is generally high.

    Rate this question:

    Which data are influenced by individual’s perceptions?I. AnthropometricII. PsychologicalIII. Physiological

    • I, II and III

    • I and II

    • I and III

    • II and III

    Correct Answer
    A. II and III
    Explanation
    The correct answer is II and III. Psychological data are influenced by an individual's perceptions because they involve thoughts, emotions, and behaviors that are subjective and can vary from person to person. Physiological data are also influenced by an individual's perceptions because factors such as stress, anxiety, and mood can affect physiological responses in the body. Anthropometric data, on the other hand, are objective measurements of the physical dimensions of the body and are not influenced by perceptions.

    • Computer aided design

    • Better qualified designers

    • More manufacturers

    • Technology

    Correct Answer
    A. Computer aided design
    Explanation
    Computer aided design (CAD) has had the most impact on the shortening of the product cycle. CAD allows designers to create and modify digital models of products, streamlining the design process and reducing the time required to bring a product to market. With CAD, designers can quickly iterate and make changes to their designs, resulting in faster prototyping and production. This technology has revolutionized the design industry by increasing efficiency, accuracy, and speed, ultimately leading to shorter product cycles.

    A “reach envelope” is the volume in 3-D space that a person can reach. Reach envelopes are used by designers, e.g. for the design of a cockpit-style workspace (see Figure 2a and 2b below).Data for which percentile range would ensure that the maximum numbers of users would be able to reach items within the workspace?

    • 99th

    • 95th

    • 50th

    • 5th

    Correct Answer
    A. 5th
    Explanation
    The 5th percentile range would ensure that the maximum number of users would be able to reach items within the workspace. The 5th percentile represents the lower end of the range, meaning that it includes the shortest reach distances. By designing the workspace to accommodate the 5th percentile, it ensures that even individuals with shorter reach capabilities can comfortably access items within the workspace.

    Which type of drawing is constructed to a set angle of 60 degrees to the vertical?

    • Orthographic

    • Dimetric

    • Isometric

    • Perspective

    Correct Answer
    A. Isometric
    Explanation
    An isometric drawing is constructed to a set angle of 60 degrees to the vertical. In an isometric drawing, the object is represented in three dimensions, with all three axes (x, y, and z) equally foreshortened. This means that the angles between the axes are all 120 degrees, with the vertical axis being at a 60-degree angle to the horizontal axes. Therefore, an isometric drawing is the correct answer for a drawing constructed to a set angle of 60 degrees to the vertical.

    Mathematical modelling is used with

    • CAD/CAM.

    • Flowcharts.

    • Algorithms.

    • Orthographic drawings.

    Correct Answer
    A. CAD/CAM.
    Explanation
    Mathematical modeling is used with CAD/CAM systems. CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) are software tools that allow engineers and designers to create and manipulate 2D and 3D models of products. These models can then be used to simulate and analyze various aspects of the design, such as stress analysis, fluid flow, or heat transfer. Mathematical modeling is an integral part of this process as it involves using mathematical equations and algorithms to represent and solve the physical phenomena being studied. Therefore, CAD/CAM is the correct answer as it specifically mentions the use of mathematical modeling in conjunction with these systems.

    Which model type is a designer most likely to use in discussions with a manufacturer?

    • Algorithm

    • Perspective drawing

    • Orthographic drawing

    • Mathematical model

    Correct Answer
    A. Perspective drawing
    Explanation
    A designer is most likely to use a perspective drawing in discussions with a manufacturer. Perspective drawings provide a realistic representation of how an object will look in three dimensions. This type of drawing allows the designer to communicate their vision and design intent to the manufacturer, giving them a clear understanding of the final product. Perspective drawings are commonly used in fields such as architecture, industrial design, and product development to convey the overall look and feel of a design.

    What is true of physical models and mathematical models?

    • They are easy to understand by clients.

    • They are 3D.

    • They represent selected features of a design.

    • They are realistic representations.

    Correct Answer
    A. They represent selected features of a design.
    Explanation
    Physical models and mathematical models are both used to represent selected features of a design. Physical models are tangible representations that can be touched and examined, while mathematical models are abstract representations that use equations and calculations to describe the design. Both types of models are used to simplify complex designs and highlight specific aspects that are important for understanding and analysis. They may not necessarily be easy to understand by clients or be 3D, and while physical models aim for realistic representations, mathematical models focus on accuracy rather than realism.

    A performance test provides

    • Aesthetics data.

    • Quantitative data.

    • Qualitative data.

    • Data about users’ opinions.

    Correct Answer
    A. Quantitative data.
    Explanation
    A performance test is designed to measure and evaluate the performance of a system, product, or service. It focuses on collecting objective and measurable data, such as response time, throughput, and resource usage. This type of data is known as quantitative data because it can be expressed numerically and analyzed statistically. Aesthetics data, qualitative data, and data about users' opinions are not typically collected in a performance test as they are subjective and not directly related to the performance of the system being tested.
