What does 'preferred futures' mean in the context of engineering design?

• A vision of the future that reflects societal values and aspirations
• A prediction of future technological advancements
• A preference for traditional designs
• A forecast of economic trends

What is a key element of design strategies in engineering? (click all that apply)

• Prioritizing safety and speed

• Focusing on user experience and functionality
• Ignoring environmental impacts
• Limiting technological innovation

Which of these is an example of a social need in car design?

• Making cars more luxurious

• Ensuring accessibility for all users

• Designing for maximum speed

• Focusing on aesthetic appeal

Answer explanation

Ensuring accessibility for all users is an example of a social need in car design. It prioritizes inclusivity and equal access for everyone, making cars more accessible and user-friendly.

An ethical need in engineering often involves:

• Ignoring user safety for innovation
• Prioritizing profit over sustainability
• Balancing technological advancement with societal impact
• Designing products with a short lifespan

What is a sustainability need in engineering design?

• Using rare materials for better performance

• Incorporating renewable energy sources

• Maximizing product size

• Focusing only on aesthetic aspects

Answer explanation

A sustainability need in engineering design is incorporating renewable energy sources for better environmental impact and long-term resource availability.

Which safety feature was first introduced in commercial cars in the 1950s?

• Anti-lock Braking System (ABS)
• Seatbelts
• Airbags
• Rear-view cameras

What is a 'need' in the context of engineering design?

• A feature added to increase product cost
• A basic requirement that the product must fulfill
• An optional aesthetic enhancement
• A tool used during the manufacturing process

Match the following car features with their primary function (Safety or Speed).​

Groups:

(a) Speed

,

(b) Safety

• Traction control systems

• Adjustable suspension

• Seatbelts

• Turbo chargers

• Airbags

• Engine Control Unit (ECU) tuning

• Racing tyres

• Anti-Locking Braking Systems (ABS)

• Spoilers

• Reinforced roll cage

• LED Headlights

• Crumple Zones

Answer explanation

1. Airbags - Pops out to protect you in a crash.

3. Spoilers - Helps the car stick to the road when going fast.

5. Seat Belts - Keeps you in your seat if there's a sudden stop or crash.

7. Turbochargers - Gives the car's engine more power to go faster.

9. Anti-lock Braking System (ABS) - Prevents the wheels from locking up during braking.

11. Racing Tires - Provides better grip on the road for high speeds.

13. Crumple Zones - Designed to absorb and reduce crash impact.

15. Engine Control Unit (ECU) Tuning - Adjusts engine settings for optimal performance.

17. Traction Control System - Prevents wheel spin during acceleration.

19. Reinforced Roll Cage - Provides a strong protective frame around the driver.

21. Adjustable Suspension - Fine-tunes how the car handles on the road.

23. LED Headlights - Brighter lights for better visibility at night.

What is a key ethical consideration in car manufacturing?

• Maximizing profit

• Minimizing cost

• Ensuring safety

• Enhancing speed

Answer explanation

Ensuring safety is a key ethical consideration in car manufacturing as it prioritizes the well-being of consumers and prevents potential harm.

Which of the following is an example of a sustainable technology in car manufacturing?

• Diesel engines

• Electric motors

• Hydraulic steering systems

• Nitrous oxide boosters

Answer explanation

Electric motors are an example of sustainable technology in car manufacturing because they produce zero emissions and are more energy-efficient compared to diesel engines and nitrous oxide boosters.
