Question 2: How does the design of the engine cooling fan affect the thermal efficiency of an automotive system?

Which action should you take?

Choose only one option

By enhancing fuel efficiency through reduced drag

By reducing the overall weight of the cooling system

By increasing air flow to improve heat dissipation

Question 3: When selecting materials for automotive powertrains, what is the key consideration regarding material density?

Which action should you take?

Choose only one option

The material must be able to resist thermal expansion

The material should be dense to increase strength

The material should have a high density for better heat absorption

The material must have a low density to reduce vehicle weight

Question 4: How does the use of aluminum affect the design of an automotive powertrain compared to steel?

Which action should you take?

Choose only one option

Aluminum is unsuitable for powertrain applications

Aluminum reduces weight and improves fuel efficiency but requires consideration of strength and fatigue resistance

Aluminum is cheaper and more durable than steel

Aluminum increases the overall weight of the powertrain

Question 5: How do you ensure that vehicle components, like doors and windows, contribute to both structural integrity and safety?

Which action should you take?

Choose only one option

By focusing only on aesthetics without considering safety features

By designing the door independently from the overall frame structure

By reducing door strength for easier opening and closing

By designing door frames and window structures to integrate with the vehicle's crumple zones and ensure occupant protection

Question 6: In automotive mechanical design, how does increasing the stiffness of a suspension system affect the vehicle's handling?

Which action should you take?

Choose only one option

It reduces the vehicle's ability to absorb impacts

It improves the vehicle's responsiveness during cornering

It decreases the comfort of the ride for passengers

It increases the risk of component failure
