GCSE Design Technology Examination Quiz

What are the properties of thermoplastics and thermosetting plastics? Provide examples of each.

• Thermoplastics cannot be melted

• Thermosetting plastics can be re-melted

• Examples of thermoplastics include rubber and glass

• Thermoplastics can be melted and re-molded, while thermosetting plastics cannot be re-melted. Examples of thermoplastics include polyethylene and polypropylene, while examples of thermosetting plastics include epoxy and phenolic.

Explain the concept of tensile strength and how it is important in material selection for product design.

• Tensile strength is the ability of a material to withstand compression forces

• Tensile strength is not important in material selection for product design

• Tensile strength is only important for flexible materials

• Tensile strength is the maximum amount of tensile (pulling) stress that a material can withstand before breaking. It is important in material selection for product design because it determines the ability of a material to withstand forces and loads without breaking or deforming.

Describe the stages involved in the product design and development process.

• Research, ideation, concept development, prototyping, testing, and final production

• Packaging, branding, pricing

• Manufacturing, advertising, sales

• Sketching, marketing, distribution

What is the importance of user feedback in the product design and development process?

• User feedback only adds unnecessary complications to the process

• User feedback is only useful for marketing purposes

• User feedback helps in identifying areas for improvement and ensures that the final product meets user expectations.

• User feedback has no impact on product design and development

Explain the difference between subtractive and additive manufacturing processes.

• Subtractive manufacturing and additive manufacturing are the same process

• Subtractive manufacturing removes material, while additive manufacturing adds material.

• Subtractive manufacturing adds material

• Additive manufacturing removes material

Discuss the role of automation in modern manufacturing processes.

• Automation has no impact on modern manufacturing processes

• Automation increases the cost of production in modern manufacturing processes

• Automation leads to a decrease in productivity in modern manufacturing processes

• Automation improves efficiency and productivity in modern manufacturing processes.

How can design technology contribute to sustainable development? Provide examples.

• By creating energy-efficient products, using renewable materials, reducing waste, and minimizing environmental impact.

• By using non-renewable materials and increasing waste

• By ignoring environmental impact and creating energy-inefficient products

• By contributing to deforestation and pollution

Explain the concept of life cycle assessment in the context of sustainability in design technology.

• It is a method used to evaluate the aesthetic impact of a product or process throughout its entire life cycle.

• It is a method used to evaluate the environmental impact of a product or process throughout its entire life cycle.

• It is a method used to evaluate the social impact of a product or process throughout its entire life cycle.

• It is a method used to evaluate the economic impact of a product or process throughout its entire life cycle.

What are the advantages of using CAD/CAM technology in the design and manufacturing process?

• Slower production, increased errors, difficult modification of designs

• Less precision, inability to simulate and test designs, increased errors

• Increased precision, faster production, reduced errors, ability to simulate and test designs, easier modification of designs.

• No impact on precision, slower production, inability to simulate and test designs

Discuss the impact of 3D printing on product prototyping and production in the design industry.

• 3D printing has led to a decrease in the quality of product prototyping and production in the design industry.

• 3D printing has made product prototyping and production in the design industry more expensive.

• 3D printing has revolutionized product prototyping and production in the design industry.

• 3D printing has had no impact on product prototyping and production in the design industry.
