1.2.2 How critical evaluations can be used to inform design decisions

Question 1

Define Synthetic

Answer 1

Synthetic: human-made

Question 2

Define Nitinol

Answer 2

Nitinol: an alloy of nickel

and titanium

Question 3

Define Alloy

Answer 3

Alloy: a metal mixed with
another metal or element
such as carbon| to improve
its properties in some way.

Question 4

Applying critical thinking to contemporary problems and potential future scenarios such as natural disasters?

Answer 4

CAD programs allow for 3D simulations of real-life disasters and help visualise how a structure might respond.

Question 5

Applying critical thinking to contemporary problems and potential future scenarios such as medical advances?

Answer 5

Emerging technology has had a major impact on the medical profession, for example the 3D printing of synthetic cartilage fits the knee joint perfectly, and the use of Nitinol (an alloy of nickel and titanium) in medical implants such as
stents

Question 6

Applying critical thinking to contemporary problems and potential future scenarios such as travel?

Answer 6

Electric cars are seen by many as the way
forward. Battery technology continues to evolve and driving range will increase. Electric cars do not produce emissions, are efficient and environmentally friendly.

Question 7

Applying critical thinking to contemporary problems and potential future scenarios such as global warming?

Answer 7

The main cause of global warming is the release of greenhouse gases such as carbon dioxide into the atmosphere. Solar and wind farms are examples of technology that can help reduce these emissions

Question 8

Applying critical thinking to contemporary problems and potential future scenarios such as communication?

Answer 8

Emerging technology in fibre optics and wireless [Bluetooth] have led to a vast range of digital devices that allow easy communication on a global scale.
