      Fitting the job or work environment to the worker 

    Correct Answer
    D. Fitting the job or work environment to the worker 
    Explanation
    Ergonomics is the science of fitting the job or work environment to the worker. This means designing and arranging workspaces, tools, and equipment in a way that maximizes efficiency and comfort for the worker. It involves considering factors such as body posture, movement, and physical capabilities to reduce the risk of injuries and improve overall productivity. Ergonomics aims to create a work environment that is well-suited to the needs and abilities of the worker, ultimately enhancing their performance and well-being.

    Detailed orthographic drawings are BEST used to show:

    • A.

      Early stages of product development

    • B.

      3D views of a finished product

    • C.

      The dimensions of a finished product for manufacturing

    • D.

      How mechanical components fit together to make a product

    Correct Answer
    C. The dimensions of a finished product for manufacturing
    Explanation
    Detailed orthographic drawings are used to show the dimensions of a finished product for manufacturing. These drawings provide accurate and precise measurements of the product, including its length, width, and height. This information is crucial for manufacturers as it helps them understand the exact size and shape of the product, allowing them to create it accordingly. Additionally, orthographic drawings also include annotations and notes that provide further details about the product, such as tolerances and material specifications, which are essential for the manufacturing process.

  • 5. 

    A technical worker in construction and manufacturing industries is paid more than a skilled or semi-skilled worker because they have

    • A.

      A better position

    • B.

      Highly academic qualifications

    • C.

      Higher levels of knowledge and skills

    • D.

      Greater production output

    Correct Answer
    C. Higher levels of knowledge and skills
    Explanation
    The correct answer is "higher levels of knowledge and skills". Technical workers in construction and manufacturing industries are paid more than skilled or semi-skilled workers because they possess advanced knowledge and skills that are necessary for their job roles. These workers typically have specialized training and expertise in their respective fields, allowing them to perform complex tasks and handle advanced machinery. Their higher levels of knowledge and skills make them more valuable to employers, leading to higher pay.

    When using a grinder, the eyes should be protected by:

    • A.

      Wearing gloves

    • B.

      Wearing goggles

    • C.

      Holding the work firmly

    • D.

      Holding the work on the tool rest

    Correct Answer
    B. Wearing goggles
    Explanation
    When using a grinder, wearing goggles is necessary to protect the eyes from any potential hazards such as sparks, debris, or fragments that may be generated during the grinding process. Gloves are not specifically designed for eye protection and may not effectively shield the eyes. Holding the work firmly and using a tool rest are important for stability and control, but they do not directly address eye protection. Therefore, wearing goggles is the most appropriate safety measure for protecting the eyes when using a grinder.

  • 7. 

    When must employers identify possible workplace hazards?

    • A.

      When the need arises

    • B.

      When directed to by authorities

    • C.

      Before workers return from lunch

    • D.

      Before making changes to work practices

    Correct Answer
    A. When the need arises
    Explanation
    Employers must identify possible workplace hazards when the need arises in order to ensure the safety and well-being of their employees. This means that they should be proactive in identifying and addressing any potential hazards or risks that may arise in the workplace, rather than waiting for an incident or accident to occur. By identifying hazards as they arise, employers can take appropriate measures to mitigate risks and create a safer work environment for their employees.

    Which of the following operations is NOT done using computer numerically controlled machines?

    • A.

      Milling

    • B.

      Plasma cutting

    • C.

      Milling

    • D.

      Filing

    Correct Answer
    D. Filing
    Explanation
    Filing is the correct answer because it is not typically done using computer numerically controlled (CNC) machines. Filing is a manual process that involves using a hand tool to remove material from a workpiece, whereas CNC machines are automated and controlled by computer programs to perform precise operations such as milling and plasma cutting.

    Computer-aided manufacturing is the use of computer software to:

    • A.

      Reduce the amount of labour-intensive activities

    • B.

      Control the manufacture of high-quality parts

    • C.

      Move work pieces around the manufacturing plant

    • D.

      Move work pieces around the manufacturing plant

    Correct Answer
    B. Control the manufacture of high-quality parts
    Explanation
    Computer-aided manufacturing (CAM) is a process that utilizes computer software to oversee and manage the production of high-quality parts. By using CAM, manufacturers can ensure precision and accuracy in the manufacturing process, resulting in consistent and reliable products. This technology allows for greater control over various aspects of production, such as tooling, machining, and quality assurance, ultimately leading to improved efficiency and reduced errors. CAM eliminates the need for manual intervention and reduces labor-intensive activities, making the manufacturing process more streamlined and cost-effective.

    A product developer is designing a number of products for a client who specifies that the products are to be used by persons of various weights and heights. Which of the following factors should he consider during the design process? 

    • A.

      Economics

    • B.

      Anthropometrics

    • C.

      Suitability of material

    • D.

      Functionality

    Correct Answer
    B. Anthropometrics
    Explanation
    The product developer should consider anthropometrics during the design process. Anthropometrics refers to the study of human body measurements and proportions. Since the products are intended to be used by persons of various weights and heights, it is important to design them in a way that accommodates the different body sizes and shapes. By considering anthropometrics, the developer can ensure that the products are comfortable, safe, and suitable for a diverse range of users.
