It is known as aerodynamic to vehicles and other objects that have adequately to reduce air resistance and maintaining performance. The word aerodynamic is of Greek origin, formed by “aero” which means “air” and “dynamos ” that expresses “force”.
The science known as aerodynamics is part of mechanics, which studies the movements related to gases and solids. The development of aerodynamic models occurred in the 1950s, particularly in race cars, as they should be designed to withstand high speeds and maintain stability, since then cars with sharp tubes are observed, similar to the cars of Formula 1.
Two basic forces act in aerodynamics: aerodynamic drag and lift. The first is the resistance force generated when an object moves in the air or water, which increases the speed and shape of the object (the greater the ability to face the resistance of the air, the greater its aerodynamic capacity). On the other hand, lift is the force that opposes the weight of the object allowing it to remain in the air, for example: aircraft.
The aerodynamic coefficient (Cx) is the value that indicates the ability of the car to break the front air. The aerodynamic coefficient must be analyzed as follows: lower value, greater breaking capacity and lower fuel consumption. In cars it should be 0.30; ATVs between 0.35 – 0.45.
Some objects that are subject to the forces of aerodynamics are: bridges, submarines and skyscrapers.
