Chapter 3 Quiz

What is the primary purpose of a model in the design process?

• To visualize and test design ideas

• To replace the final product

• To increase the cost of production

• To reduce the lifespan of a product

Which of the following is an advantage of using computer-aided design (CAD) software for virtual modelling?

• Increases the complexity of communication

• Reduces the ability to share models globally

• Enhances accuracy and precision

• Limits the designer's creative options

Which of the following is NOT a characteristic of a physical model?

• Provides a tangible representation of the design

• Can be used for user testing and ergonomic analysis

• Can be easily modified without rebuilding

• Often used to simulate real-world behavior

What is a limitation of using a mathematical model in the design process?

• Inability to visualize the physical appearance

• High cost of materials

• Limited accuracy in testing physical interactions

• Requires physical prototypes for validation

Which type of model is typically used during the initial stages of the design process to explore basic ideas?

• Prototype

• Virtual model

• Conceptual model

• Mathematical model

In which scenario would a designer most likely use a clay model?

• To perform aerodynamic testing

• To evaluate ergonomic factors

• To determine exact dimensions for production

• To create a mathematical representation

Which of the following best describes a mock-up?

• A functional prototype used for testing final design performance

• A scaled-down version of the final product used in marketing

• A full-size but non-functional physical model used for visualizing form and space

• A mathematical equation used to predict a product's performance

What is the main benefit of using rapid prototyping techniques, such as 3D printing, in modelling?

• It reduces the need for conceptual models

• It allows for quick production of physical models

• It eliminates the need for virtual models

• It increases the production cost

What is the role of a wireframe model in the design process?

• To test the strength of materials

• To provide a detailed visual of the internal components of a product

• To simulate the product's behavior under various conditions

• To represent a skeletal outline of a 3D model without surface details

How do mathematical models differ from physical and virtual models in design technology?

• Mathematical models provide visual and tangible representations

• They are primarily used for testing physical characteristics of the product

• They use equations and data to predict outcomes without physical representation

• Mathematical models can only be used in the final stages of design
