AQA GCSE Design and Technology
Four main stages that make up an electronic system - correct answer ✔Input
device
Process
Output device
Driver stage
Miccrocontrollers - correct answer ✔Can be programmed to add functionality
to products, such as timing and counting
Light-dependent resistor - correct answer ✔Has a resistance that changes
depending on the light level
Thermistor - correct answer ✔Has a resistance that changes depending on
temperature
Market research - correct answer ✔Information is collected to find out
whether there is a place in the market for a proposed product
Focus group - correct answer ✔A group of people assembled to discuss and
give feedback on a product or design idea
Virtual meeting technologies - correct answer ✔Allow designers to meet with
clients almost anywhere in the world
Presentation software - correct answer ✔Used to create visual aids for a
presentation
,Computer-aided design (CAD) software - correct answer ✔Can be used to
draw, model and simulate ideas
Rotating motion - correct answer ✔Movement in a circle
Linear motion - correct answer ✔Goes in a straight line direction
Reciprocating motion - correct answer ✔Moving backwards and forwards
Oscillating motion - correct answer ✔Swinging backwards and forwards, like
a pendulum
Levers - correct answer ✔A simple form of machine
Fulcrum - correct answer ✔The fixed point around which a lever pivots
First-order lever - correct answer ✔The fulcrum is between the load and the
effort
Second-order lever - correct answer ✔The load is applied between the effort
and the fulcrum
Third-order lever - correct answer ✔The effort is applied between the load
and the fulcrum
Linkages - correct answer ✔Used to transfer motion between two positions
, Push-pull linkage - correct answer ✔Can reverse the direction of linear
motion
Bell crank - correct answer ✔Changes the direction of motion by an angle,
for example 90°
Cams - correct answer ✔Typically used to convert rotary motion to
reciprocating motion
Strength - correct answer ✔Ability to withstand a force or load
Elasticity - correct answer ✔Ability of a material to return to its original shape
when a force on it has been removed
Ductility - correct answer ✔Amount that a material can be permanently
stretched or deformed when a force is applied to it
Malleability - correct answer ✔Ability of a material for its shape to be
permanently changed without breaking
Hardness - correct answer ✔Ability of a material to resist wear or being
scratched
Toughness - correct answer ✔Ability of a material to not break when a force
is applied to it suddenly
Fusibility - correct answer ✔Ability of a material to be changed from a solid to
a liquid by heat
