Why do I Dragster? A question that at first may sound really weird. This question actually asks why would you want to race C02 cars. First, to understand what this is, lets start with the Basics. Co2 Dragsters as they are called are essentially small Race cars. They are propelled by a small Carbon Dioxide Cartridge in the back of the car. This cartridge is Pierced, and then releases the colorless and odorless gas. They are often used to demonstrate mechanical principles, such as Mass, Force, Acceleration, and Aerodynamics. Two screw eyes are attached to a string (usually fishing line).to keep the racer on the path. Most Co2 dragsters are carved out of balsa wood and or Basswood because of the light weight. Co2 dragsters are used in part …show more content…
Simply put, the less weight your dragster has, the faster it will go. This is the most important factor that will figure into your design. Keep it light! Friction: The second most important fact you'll face. Because the dragster has parts moving against one another, friction is created. You can help reduce it by making sure the axles are free to rotate, and that the wheels and tires are not rubbing on the car body. Drag: Here's where aerodynamics come into play. As an object moves through the air, it is met with air resistance as speeds increase. This air resistance pushes against your CO2 car and prevents it from going as fast as it could in a vacuum. You can't completely ever reduce drag, but you can help reduce it by building a more aerodynamic car, but those are more difficult to create. Now To talk about the forces that allow the car to move. There are two main aerodynamic forces acting on any object moving through the air. Lift is a force that acts 90° to the direction of travel of an object. Usually we think of lift when we think of an airplane. The plane travels forward (horizontally), and lift acts 90° to that motion of travel –
Carbon Dioxide (CO2) is a colorless gas, which was first discovered in 1577 by Van Helmont who detected it in the products of both fermentation and charcoal burning. CO2 is used in solid, liquid, and gas forms in a variety of industrial processes. These include: beverage carbonation, dry ice, welding and chemicals manufacturing. It is produced by the combustion of all carbonaceous fuels and can be recovered in an abundance of ways. It is widely used today as a by-product of synthetic ammonia production, fermentation, and from flue gases by absorption process. CO2 is also a product of animal metabolism and is important in the life cycles of plants and animals. It is present in the atmosphere only in small quantities (.03% by vol.)
The purpose is to drive more, it is not important to compete with cars, it is not important to win, it is important to be on the road.
The faster the wheels spin, the faster the car will go. Our project requires our car to go at least 3 meters. Our initial trials were successful because our car went 7,8, and then 9 meters. The car went 7 meters in 8 seconds with a speed of 0.875 m/s. It went 8 meters in 10 seconds with a speed of 0.8 m/s. It finally went 9 meters in 12 seconds with a speed of 0.75 m/s. It is what makes the wheel spin instead of just sliding on the ground.
The word demolition means collisions and hitting two objects together while derby mean a race. These two words put together creates a competitive place for people to enjoy derby cars. Demolition derby drivers come from long family history of drivers. The pasion starts when they are old enough to walk, helping dad at the garage. He can remember their first demolition derby going forty miles per hour, smashing into another car and coming in third. From that moment on, he was hooked. From my experience and research, I know there is a lot of time and effort that goes into building the car, participating in the demo derby, and keeping a driver and spectators safe and these are the three areas of focus on in this paper.
Looking up, you see that it is almost your turn. After getting off the hood of the car, open the door, and sit inside the vehicle. As you firmly grasp the wooden steering wheel, the scent of unleaded gasoline fills the air, the rigid feel of the leather racing seat brushes skin, and the warm touch of chrome on the shifter radiates through the car. Sliding the key into the ignition, you turn it and hear the low grumble of the HiPo 302 cubic inch engine. You shift the car into first gear and begin to creep forward to the drag strip.
Take a look at your car, it probably can only hit eighty on a good day. Then watch the top fuel and funny car dragsters of the National Hot Rod Association who get three hundred miles per hour on a bad day. You would be blown away at the diffrence in power. The pure power and the amount of noise that these cars produce will blow you away. I'm going to inform you on a lot of the amazing facts about the nitro powered dragsters of the NHRA. First, i'm going to inform you on how drag racing started and on how drag racing works, then how the dragsters work. Following that i'm going to explain how the equipment keeps the drivers and workers safe, finally I will explain how the sport is evolving,
Hundreds of thoughts swarm through my head, as I think of potential car and launcher designs. It was the beginning of 8th grade. A new year of middle school, a new year of Science Olympiad, a new year of studying for my events, and a new year of challenges: my first building event, Scrambler. I’ve always been interested in science, specifically medicine, ever since I was 7 or 8. I read a book called When I Grow Up, I Want to Be a Doctor, which inspired me to aspire to become a doctor. Ever since then, I’ve been exploring the field of science and medicine through a variety of learning experiences such as Science Olympiad, a science competition consisting of several events that cater to a variety of fields in science. This year, my partner and I were faced with the task of building a mechanical vehicle, powered by a falling mass, that is capable of traveling down a straight, level track with a barrier at the end while carrying an
Over his years in the racing world, Ricky Johnson has firmly established himself as a versatile and formidable champion. He has always proven to his fans and his competition that he can handle a range of vehicles, terrains, and events. From his early days as a motocross and supercross competitor to his later adventures in off-road and stock car racing, Johnson has never failed to impress. Fans will just have to wait and see what new tricks Johnson may have up his
Drag is a major contributor to how an object travels through fluid/air. Drag is caused by the disrupted air immediately behind an object moving through fluid/air. It acts perpendicular to and in the opposite direction of travel of the object and impedes the motion of the object. It would make sense that if the drag is minimized the object will travel farther.
The tradeoffs of using gasoline for cars are large emission of carbon dioxide and required large amount of chemical t...
Fuel efficiency in automobiles has become a topic of much discussion in recent years in the United States. This is due largely to the environmental devastation that fuel emissions cause, but it is also sparked by the rising fuel costs. Making cars with high fuel efficiency not only saves consumers money, but also will drastically reduce the pollution that is caused by emissions. Today automakers are putting a tremendous amount of effort into making their cars more fuel efficient, both to meet government regulations and to make their car more appealing to the consumer.
Cars are a fantastic invention. They make our lives even more carefree by getting us from place to place quickly while eradicating the need for legs altogether. There is no doubt that the benefits of driving from place to place are numerous. However, driving takes a whole lot of fuel, and everyone knows that fuel for cars isn’t the most plentiful (or cheapest!) of resources.
In order to have a fast and efficient car all these things I have discussed need to be taken into consideration. A fast car should be designed with aerodynamic surfaces for a balance of maximum production of downforce and minimum drag creating surfaces. It should have as small an engine as possible to reduce mass and reduce the necessary size of the frontal area, but a large enough engine to be able to produce enough horsepower to be able to create more force than the resistance the car faces to accelerate and enough to balance with those forces at high speeds. The tires should be wide enough for fast acceleration and good cornering but not so wide it creates large amounts of rolling resistance. Your overall best example of such a car would be formula one races or Indy cars because they have to have good handling, fast acceleration and reach and maintain high speeds.
The four forces that help a rubber band airplane fly are thrust, air drag, lift, and gravity. Thrust is important in making a rubber band airplane fly because it propels the airplane forward and without thrust your airplane would never take-off. Air drag is also important in making a rubber band airplane fly because air drag is when air is hitting the surface area of the airplane. Lift is important also because it is the ability to overcome gravity, which makes the airplane leave the ground. Another crucial thing for an airplane to fly is gravity. Gravity pulls the plane down while
Even when cars capable of these speeds are put into the hands of world-class drivers such as Ferrari’s Michael Shumacher and McLaren’s Mika Hakkinen, mishaps are bound to occur. This is what makes this sport so exciting to watch. Crashes however, are not the only exciting events of the race. It is thrilling to watch a car out brake another in order to squeeze its way ahead, or to watch the cars bump tires in an effort to occupy the same piece of race track to be set up correctly for the turn ahead. Other points of interest are the pit stops and the strategies that the various teams use in order to make a fast pit stop.
