Drag (Air Resistance) The force acting opposite to the relative motion of any object moving with respect to a surrounding fluid (in this case air).

Drag Coefficient The measure of drag of an object.

Drag Profile The sum of the surface friction drag and the form drag for a body moving subsonically through a fluid

Friction The resisting force of surfaces to a moving object

Lift The component force of fluid passing through an object that is perpendicular to the oncoming flow direction. Aerodynamics

Weight - The force on an object due to gravity.

Grip Force - The term describing the total cornering envelope of a race car by the friction component of the

Downforce - The downwards thrust created by the aerodynamic characteristics of a car.

Traction - The force used to generate motion between a body and a tangential surface Bernoulli Effect

The increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. Mechanical Terms

Kammback - A is a car body style that derives from the research of the German aerodynamicist Wunibald Kamm in the 1930s. A car body style that includes a smooth top back that ends at the tail. This body style reduces drag

Car Exterior - Exterior detailing involves cleaning and restoring or exceeding the original condition of the surface of the car's finish, chrome trim, windows, wheels, and , as well as other visible components on the exterior of a vehicle. Defines how aerodynamic a car is. How fast it goes.

Rear Spoiler Fin - A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion, usually described as turbulence or drag.

Wing - A wing is a type of fin that produces lift, while moving through air or some other fluid. Car Model Inspiration

● Molding the car to your desire after 3d printing it was hard ● Doesn’t perfectly come out as expected ● Designing the car was also hard ● Design the car out of scratch instead of using the autodesk fusion as a template ● Autodesk Fusion and fusion flow to design and make adjustments to my car accordingly to aerodynamics ● Technical drawing skills improved ● Learned ○ Sanding (which specific sanding tool to use) Personal Reflection

● With mutliple project deadlines, work management improved ● This class helped me be a better learner through self learning of tutorials ● Designing the car has made me a better thinker ● Being able to use multiple forms a media on this presentation will help me improve with communication ● This class has shown and given me the option to contribute to the world through engineering. bibliography https://en.wikipedia.org/wiki/Aerodynamics https://en.wikipedia.org/wiki/Automotive_aerodynamics https://en.wikipedia.org/wiki/Drag_(physics) https://en.wikipedia.org/wiki/Lift_(force) www.baysideautoworks.com/Spring%20Hill-auto-maintenance.html
