Description
In Transportation Modeling, you will be tasked with researching, designing, and creating a scale model of the vehicle that fits the annual design statement. This is a prepared event, meaning you will have to create a product to bring and present at the conference.
This is a solo event.
At the conference, you will submit a display, scale model, and documentation portfolio.

Helpful Terminology
Helpful Terminology
Aerodynamics: How air flows around a vehicle; affects speed, drag, and efficiency.
Drag: Resistance caused by air; reducing drag makes vehicles faster and more efficient.
Lift: The upward force from airflow; can cause instability in cars if not controlled.
Downforce: The downward pressure created by airflow; improves grip and handling.
Coefficient of Drag (Cd): A measurement of how aerodynamic a shape is; lower means less resistance.
Chassis: The structural frame of the vehicle that supports all components.
Body: The outer shell that defines the vehicle’s shape and appearance.
Weight Distribution: How mass is spread across the vehicle; affects balance and stability.
Wheelbase: The distance between front and rear axles; impacts handling and turning.
Rolling Resistance: Friction between wheels and the surface; lower resistance means better speed.
Center of Gravity (CG): The point where weight is balanced; lower CG improves stability.
