A race car is tested in a wind tunnel for structural analysis. The wind at 2°C with a velocity of 138 km/h is blowing parallel to the side of the car. Assuming that the car only has 4 sides, What is the purpose of this test?
1) To measure the aerodynamic forces acting on the car
2) To determine the structural integrity of the car
3) To test the car's performance in different wind conditions
4) To evaluate the car's fuel efficiency
