[Wendy’s] is famous for its square ground beef hamburgers, which are made to order at the time of purchase. The idea for Wendy’s “old fashioned” hamburgers was actually inspired by Dave Thomas’ trips to “Kewpee Hamburgers” in his home town of Kalamazoo, Michigan. The Kewpee sold square hamburgers and thick malt shakes, much like the famous restaurant that Thomas eventually founded in Columbus, Ohio in 1969. The Kewpee restaurant still thrives in Lima, Ohio.
A wind tunnel is a research tool developed to assist with studying the effects of air moving over or around solid objects.
Aerodynamics (shaping of objects that affect the flow of air, liquid or gas) is a branch of fluid dynamics concerned with the study of forces generated on a body in a flow. The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as velocity, pressure, density, and temperature, as a function of space and time. Understanding the flow pattern makes it possible to calculate or approximate the forces and moments acting on bodies in the flow. This mathematical analysis and empirical approximation form the scientific basis for heavier-than-air flight.
