AQA Design and Technology Quiz

Which of the following is a property of aluminium that makes it suitable for use in aeroplane bodies?

• High density

• Corrosion resistance

• Poor electrical conductivity

• Brittle nature

Answer explanation

Aluminium's corrosion resistance is crucial for aeroplane bodies, as it helps prevent damage from environmental factors, ensuring durability and safety. High density, poor conductivity, and brittleness are not desirable properties for this application.

Which material is most suitable for making a chopping board due to its hardness and resistance to knife marks?

• Pine wood

• Oak wood

• Polystyrene

• Aluminium

Answer explanation

Oak wood is ideal for chopping boards due to its hardness, which helps resist knife marks and wear. Unlike softer woods like pine, oak maintains its surface better, making it a durable choice for food preparation.

Which of the following is an example of a thermoplastic?

• Epoxy resin

• Polyethylene

• Melamine formaldehyde

• Bakelite

Answer explanation

Polyethylene is a thermoplastic, meaning it can be melted and reshaped multiple times. In contrast, epoxy resin, melamine formaldehyde, and Bakelite are thermosetting plastics, which cannot be remolded after curing.

What is the main aim of sustainable design?

• To reduce production costs

• To minimise environmental impact

• To increase product lifespan only

• To use the most expensive materials

Answer explanation

The main aim of sustainable design is to minimise environmental impact by creating products and systems that are eco-friendly, reducing waste and resource consumption, rather than focusing solely on cost or material expense.

Which of the following is a renewable material?

• Steel

• Glass

• Bamboo

• Polycarbonate

Answer explanation

Bamboo is a renewable material because it grows quickly and can be harvested sustainably. In contrast, steel, glass, and polycarbonate are derived from non-renewable resources and do not regenerate naturally.

Which design practice helps reduce waste during manufacturing?

• Overproduction

• Just-in-time production

• Mass production

• Batch production

Answer explanation

Just-in-time production minimizes waste by producing only what is needed, when it is needed, reducing excess inventory and resource use. This contrasts with overproduction and mass production, which can lead to significant waste.

Which of the following is NOT a product analysis technique?

• Disassembly

• User testing

• Market research

• Injection moulding

Answer explanation

Injection moulding is a manufacturing process, not a product analysis technique. Disassembly, user testing, and market research are all methods used to analyze and evaluate products.

What is the purpose of a SWOT analysis in product design?

• To test product strength

• To identify strengths, weaknesses, opportunities, and threats

• To measure product weight

• To calculate production costs

Answer explanation

A SWOT analysis helps in product design by identifying strengths, weaknesses, opportunities, and threats, allowing designers to make informed decisions and improve the product's market fit.

Which manufacturing process is best suited for producing thousands of identical plastic bottles?

• Hand carving

• Injection moulding

• Sand casting

• Vacuum forming

Answer explanation

Injection moulding is ideal for mass production of identical items like plastic bottles, as it allows for high efficiency and precision in creating large quantities quickly, unlike hand carving or sand casting.

Which process is commonly used to join two pieces of metal together?

• Gluing

• Welding

• Sewing

• Stapling

Answer explanation

Welding is the process commonly used to join two pieces of metal together by melting the edges and allowing them to fuse. Other options like gluing, sewing, and stapling are not suitable for metal joining.
