Design and Technology Flashcards

What does LED stand for in electronics?

Answer: Light Emitting Diode

LED stands for Light Emitting Diode, a semiconductor component that emits light when an electric current passes through it in the forward direction.

Which sustainable design concept focuses on creating products that can be easily taken apart so their materials can be recovered and recycled?

Answer: Design for disassembly

Design for disassembly (DfD) involves designing products so components can be easily separated and recycled at the end of the product's life, reducing environmental waste.

Which manufacturing process heats a thermoplastic sheet until soft, then uses reduced air pressure to pull it over a mould to form a shape?

Answer: Vacuum forming

Vacuum forming heats a thermoplastic sheet until pliable, then uses a vacuum to pull it tightly over a mould, producing a shaped plastic product.

What is the main purpose of quality control in a manufacturing process?

Answer: To ensure products meet the required standards and specifications consistently

Quality control involves checking products at various stages of production to ensure every unit meets the required standards, dimensions, and performance criteria.

What does CAD stand for in design and technology?

Answer: Computer-Aided Design

CAD stands for Computer-Aided Design, referring to software used to create precise 2D drawings and 3D models of products and components.

Which of the following is a ferrous metal?

Answer: Mild steel

Mild steel is a ferrous metal because iron is its primary component; ferrous metals contain iron and are generally magnetic.

When evaluating a completed product against the original design specification, which approach is most appropriate?

Answer: Testing each design criterion listed in the specification systematically

Systematically testing each criterion in the design specification objectively determines whether the product has successfully met all of its stated requirements.
