F- words (not what you are thinking)
A feature of some wind tunnels that involves the introduction of a visible vapor into the moving airstream. This enables racers to see how their car performs in an airstream. Drag inducing body features can be easily identified.
What is Flow Visualization?
A small handheld saw with a narrow blade, useful for making curved cuts in wood. Good for rough shaping race car bodies if a band saw is unavailable.
What is a Coping Saw?
The force that resists an object’s movement through the air. The more the object disrupts the laminar flow of air around it, the more drag is developed.
What is Drag?
To have balance, or to have the same shape or size on opposite sides.
What is symmetry?
A CO2 race car design in which a narrow rail connects the front axle to the back of the car and has wheels mounted on the outside of the car body.
What is a rail car?
Part of launch pod assembly with sharp pointed end that punctures a hole in cars’ CO2 cartridges to start a race. Made of hardened steel.
What is a firing pin?
A sanding machine in which the sandpaper is carried on a small-diameter vertical drum located on the work table of the machine
What is a Spindale Sander
The force that propels an object, sets it into motion, or keeps it moving.
What is Thrust?
Describing an object’s visual appeal or attractiveness.
What is the aesthetic?
A CO2 race car design in which two wheels are housed inside the body and two are mounted externally.
What is a hybrid?
The force that resists relative motion between two objects in contact.
What is Friction?
A high-speed hobby power tool that works well for intricate shaping, cutting, drilling, sanding, and polishing. A variety of bits give rotary tools excellent versatility. It is often referred to as a Dremel, which is a popular brand name.
What is a Rotary Multi Tool?
The aerodynamic force that pushes upward on a body as it moves through an airstream.
What is Lift?
The properties and forces produced as an object moves through the air or a stream of air moves around an object.
What are Aerodynamics?
A CO2 race car design in which all four wheels are housed inside the body of the car.
What is a shell car?
The race system component that is located on the finish line of the racetrack. As the two cars speed through the gate, individual sensors detect their presence, stopping the system’s electronic timers.
What is the Finish Gate?
A bench-mounted or freestanding power tool used to make precise, curved cuts that is ideal for rough shaping CO2 car bodies.
What is a Band Saw?
The act of slowing a moving object. In CO2 racing, a car must be safely decelerated after it crosses the finish line.
What is Decelerate?
The area of the racetrack before the starting line, on the extreme end. Pairs of cars are placed in this area (after they are threaded onto the monofilament guideline) to await their turn to race.
What is the Staging Area?
A race car that races a short distance on a straight track. CO2 race cars are often referred to as dragsters.
What is a Dragster?
is a push or pull upon an object resulting from the object's interaction with another object.
What is Force?
A bench-mounted or freestanding power tool used for drilling precise holes. Particularly useful for drilling properly aligned axle holes in the car body.
A turbulent flow of air that moves in a random tumbling, or circular, pattern.
What is Eddie?
A small, quick sketch used to rapidly communicate ideas.
What is a Thumbnail Sketch?
A race car with external wheels that has a triangular wedge body shape.
What is a wedge car?
