Question

which of the following would more likely be involved in computing the wind stress on a building?
a cryogenics
b aerodynamics
c thermodynamics
d electromagnetics

Explanation:

Cryogenics studies low temperatures; thermodynamics focuses on heat/energy; electromagnetics deals with electric/magnetic fields. Aerodynamics is the study of air flow and forces (like wind stress) on objects, which directly applies to computing wind stress on a building.

Answer:

B. aerodynamics
