2D CAD is used to draw:
- A.
Top view designs and plans
- B.
3D components
- C.
Top view designs
- D.
2D components
Correct Answer
A. Top view designs and plansExplanation
2D CAD is used to draw top view designs and plans because it allows users to create accurate and detailed representations of objects or spaces from a top-down perspective. This type of CAD software is commonly used in architectural, engineering, and construction industries to create floor plans, site plans, and other technical drawings that provide a clear and comprehensive view of the design from above. By using 2D CAD, designers can easily visualize and communicate their ideas, make precise measurements, and create documentation for construction or manufacturing purposes.Rate this question:

3D CAD is used to draw:
- A.
Top view designs and plans
- B.
3D components
- C.
Top view designs
- D.
2D components
Correct Answer
B. 3D componentsExplanation
3D CAD is used to draw 3D components. This means that it is used to create and design objects or parts that have three-dimensional shapes and dimensions. Unlike 2D components, which are flat and have only length and width, 3D components have depth as well. With 3D CAD, designers can accurately represent the shape, size, and spatial relationships of these components, allowing for more realistic and detailed designs.Rate this question:

Which of the following is not true about Traditional design work?
- A.
Drawing plans by hand takes time and needs a lot of accuracy.
- B.
Different views need to be drawn manually.
- C.
If a part of a plan goes wrong then it all needs to be redrawn.
- D.
If an error is not detected the product will still be OK.
Correct Answer
D. If an error is not detected the product will still be OK.Explanation
Traditional design work involves drawing plans by hand, which is a time-consuming process that requires a high level of accuracy. Different views also need to be manually drawn. If a part of a plan goes wrong, the entire plan needs to be redrawn. However, if an error is not detected, it can lead to significant issues in the final product. Therefore, the statement "If an error is not detected the product will still be OK" is not true about traditional design work.Rate this question:

Which of the following is a way CAD does not help team working?
- A.
Designs can be emailed or stored on a server so more than one person can access them.
- B.
Copies of designs can be printed using a plotter or A3 printer.
- C.
The software can check the design meets rules.
- D.
Parts can be designed by different people and the software can check they fit together.
Correct Answer
C. The software can check the design meets rules.Explanation
CAD (Computer-Aided Design) is a software that aids in the creation, modification, and optimization of designs. It provides various tools and features to enhance team collaboration and efficiency. However, the statement "The software can check the design meets rules" suggests that CAD does not help team working in this aspect. This means that CAD may not have a built-in feature to automatically validate designs against specific rules or standards, which could potentially hinder effective teamwork and quality control.Rate this question:

Which of the following is not a disadvantage of CAD?
- A.
The software has a lot of different tools for drawing
- B.
Users need to learn a lot before they can use CAD effectively
- C.
You need a powerful monitor and high quality screen
- D.
CAD packages can be very expensive
Correct Answer
A. The software has a lot of different tools for drawingExplanation
The given answer states that "The software has a lot of different tools for drawing" is not a disadvantage of CAD. This implies that having a variety of tools for drawing is actually an advantage of CAD. Having a wide range of tools allows users to have more flexibility and creativity in their designs. It also enables them to efficiently and accurately create complex drawings or models. Therefore, the given answer suggests that having a lot of different drawing tools is a positive aspect of CAD, rather than a disadvantage.Rate this question:

CAM is:
- A.
Computer Aided Making
- B.
Computer Abetted Manufacture
- C.
Computer Abetted Making
- D.
Computer Aided Manufacture
Correct Answer
D. Computer Aided ManufactureExplanation
CAM stands for Computer Aided Manufacture. This term refers to the use of computer software and hardware to control and automate manufacturing processes. It involves the use of computer systems to design, plan, and control the production of goods. CAM technology enables manufacturers to improve efficiency, accuracy, and productivity by automating tasks such as product design, toolpath generation, and machine control. It plays a crucial role in various industries, including automotive, aerospace, and electronics, by streamlining the manufacturing process and reducing errors.Rate this question:

How has CAM negatively impacted workshops?
- A.
Production can be sped up
- B.
Human error is removed
- C.
Skilled people need to retrain or lose their job
- D.
Ntelligent machines can read the CAD designs directly
Correct Answer
C. Skilled people need to retrain or lose their jobExplanation
CAM (Computer-Aided Manufacturing) has negatively impacted workshops because it requires skilled individuals to retrain or risk losing their jobs. With the introduction of intelligent machines that can read CAD (Computer-Aided Design) designs directly, the need for human intervention and expertise is reduced. This means that individuals who were previously skilled in traditional manufacturing methods may need to acquire new skills or face unemployment as their roles become obsolete.Rate this question:

Which of the following is usually employed in the open-loop control system?
- A.
Stepper motor
- B.
Servo motor
- C.
DC motor
- D.
Induction motor
Correct Answer
A. Stepper motorExplanation
A stepper motor is usually employed in an open-loop control system because it provides precise control over the position and speed of the motor shaft. It operates by converting electrical pulses into discrete mechanical movements, allowing for accurate positioning without the need for feedback. This makes it suitable for applications where precise control is required, such as in robotics, CNC machines, and 3D printers. Unlike servo motors, which rely on feedback to adjust their position, stepper motors can be controlled directly without the need for additional sensors or feedback mechanisms.Rate this question:
