Question

When the Wright brothers designed their aircraft, they built a wind tunnel to model the aerodynamics of different wing designs. Identify each of the factors below as endogenous or exogenous to the Wright brothers' model.

Answer 1

Answer:

Endogenous factors (variables that can be controlled when performing a model test):

• aircraft speed
• wing angle

The Wright brothers used the wind tunnel to improve the design of their aircraft's wings.

Exogenous factors (variables that cannot be controlled when performing a model test):

• wind and rain
• air pressure

No one can control the climate.
