Question 1: How do you design the structural framework of a vehicle to maximize crashworthiness while minimizing weight?

Which action should you take?

Choose only one option

By reducing the size of the crumple zones for better space utilization

By using the heaviest materials available to increase strength

By minimizing the number of parts to reduce weight

By integrating high-strength, lightweight materials and designing crumple zones for energy absorption

Question 2: In injection molding for automotive interiors, what is the primary purpose of using a hot runner system?

Which action should you take?

Choose only one option

To simplify the mold design

To increase the viscosity of the molten plastic

To reduce cycle time by eliminating the need for runners to cool and solidify

To enhance the color uniformity of the parts

Question 3: How do you address the challenge of weight reduction in vehicle frame design while maintaining strength and safety?

Which action should you take?

Choose only one option

By using high-strength lightweight materials such as aluminum alloys or composites

By using cheaper, heavier materials to reduce cost

By reducing the size of the frame

By ignoring safety features to reduce weight

Question 4: In the context of automotive structural design, what does the term "crash simulation" primarily involve?

Which action should you take?

Choose only one option

Analyzing the vehicle's electrical system under impact conditions

Testing the vehicle's aerodynamics in a wind tunnel

Using computer models to predict the vehicle's behavior during crash events

Simulating the vehicle's thermal response under high temperatures

Question 5: What role does the thermostat play in maintaining optimal engine temperature in an automotive thermal system?

Which action should you take?

Choose only one option

It circulates coolant through the engine without controlling temperature

It serves only to increase fuel efficiency

It increases engine temperature for better performance

It regulates coolant flow to maintain a constant engine temperature by opening or closing at specific temperatures

Question 6: For automotive battery casings, which polymer is preferred due to its impact resistance and chemical stability?

Which action should you take?

Choose only one option

Acrylonitrile Butadiene Styrene (ABS)

Nylon (PA)

Polycarbonate (PC)

Polypropylene (PP)
