Final answer:
The group of design engineers from Ford testing the Mustang Shelby are engaged in engineering. They are using the test results to improve fuel consumption and maneuverability in the car. By analyzing the aerodynamics of the car, engineers can reduce drag force and increase fuel efficiency.
Step-by-step explanation:
The group of design engineers from Ford who tested the Mustang Shelby at a hot test track in Arizona are engaged in engineering. Specifically, they are involved in the field of automotive engineering, which focuses on designing and improving cars.
By testing the Mustang Shelby's performance at extreme temperatures, the engineers can gather data on its fuel consumption and maneuverability. This information can be used to make improvements to the car's design, with the aim of enhancing its efficiency and performance.
For example, by analyzing the aerodynamics of the car's body shape, engineers can determine how to reduce the drag force caused by air flowing around the car. This can lead to improved fuel efficiency. The engineers may use physical models or computer simulations to study the airflow patterns and make adjustments to the design accordingly.
