Question 2: What is the primary aerodynamic challenge when designing high-performance electric vehicles?

Which action should you take?

Choose only one option

Optimizing yaw moments

Reducing rolling resistance

Minimizing drag while maintaining cooling

Increasing lift to improve efficiency

Question 3: How do "slip" and "no-slip" boundary conditions affect the results of a CFD simulation for vehicle aerodynamics?

Which action should you take?

Choose only one option

Slip boundary conditions reduce drag

No-slip boundary conditions typically result in higher drag

No-slip conditions are irrelevant to drag calculations

Slip boundary conditions result in higher drag

Question 4: What is the role of a "strut" in a wind tunnel test setup?

Which action should you take?

Choose only one option

To stabilize the vehicle model

To measure air pressure at various points

To generate artificial turbulence

To simulate road surface interaction

Question 5: How does the coefficient of drag (Cd) directly influence the top speed of a vehicle at constant power output?

Which action should you take?

Choose only one option

Lower Cd has no effect on top speed

Higher Cd reduces power consumption at high speed

Higher Cd increases the drag force, reducing top speed

Lower Cd increases the vehicle's top speed

Question 6: In automotive wind tunnel testing, what is the typical method used to measure drag force?

Which action should you take?

Choose only one option

Using laser Doppler velocimetry

Using pressure sensors along the vehicle body

Using a force balance system

Measuring the vehicle's speed
