How does a CO2 car work?
CO2 cars are propelled by carbon dioxide rapidly escaping from the cartridge. The cartridge is positioned in the car so that the escaping gas moves rearward. The rearward force of the escaping gas is the initial action described by Newton. The reaction part of Newton’s law is fulfilled by the car’s movement.
What makes a CO2 car fast?
Aerodynamics, thrust-to-weight ratio, surface drag, rolling resistance and friction–all play a role in what makes a CO2 car fast or slow.
What shape makes a car go faster?
The shape of the chasis is similar to an upside down airfoil. The air moving under the car moves faster than that above it, creating downforce or negative lift on the car. Airfoils or wings are also used in the front and rear of the car in an effort to generate more downforce.
What are co2co₂ dragsters?
CO₂ dragsters are miniature racing cars which are propelled by a carbon dioxide cartridge. Required Materials: ( Wheels can be 3d printed from the tinkercad file) The best way to start is with concept sketches, also known as thumbnail sketches. These are small, quick sketches used by designers to quickly communicate ideas.
How do you test a CO2 car?
Insert the CO2 cartridge into the hole in the back of car. 5. Screw eyes are optional but can be used to run a string or wire through them to make sure the car goes in a straight path on a CO2 car track. 6. Roll test the car on a smooth, horizontal surface.
How do you draw a car design?
Draw the top and side views. Make light projection lines from one view to the other to help you locate axle holes and other features of your design. Show the location of hidden details (such as the cartridge hole) by using dashed lines. Check the specifications. Look at your design sketch to see how each spec applies to your design.
What is a working drawing for a car?
WORKING DRAWINGS The working drawing is a precise, 1:1 scale drawing that describes your car and its features. Working drawings should have top and side, or profile, views. An accurate working drawing is important for two reasons: 1) A copy of the working drawing serves as a template for rough-cutting your car blank.
