Abstract— Every second in a racing competition counts the performance of a team against the other. Many innovative and sophisticated techniques are being employed to overcome loses in time and add to the performance of the vehicle. Especially in a car racing challenge there is more freedom to install these innovative systems to empower the car to maximum efficiency due to availability of more space. At the global spectrum there are few events which encourage such innovations. Formula Student Racing competitions are one of the global events organized by the Society of Automotive Engineers of different countries which gives

Like any racing event, a student racing event also has the thrill and intensity of competition. Minimal lap timings are the concern of all the participating teams. Along with good acceleration and high velocity, a good deceleration is an important parameter which decides the performance of the vehicle. A good amount of deceleration is required especially while maneuvering sharp corners [2]. Besides, the Formula Student racing event is classified into static events and dynamic events. In order to qualify to the dynamic events every team must clear the scrutinizing which include the brake test [3] wherein every car should brake in a straight line between two marked lines on the track. It can be accounted that better deceleration is required to execute smooth cornering and qualify the brake test. In order to increase the braking ability of the car, the drag created while steering can be utilized. The aerodynamic wings also known as the spoilers can be modified to capture the drag force created due to the motion of the vehicle and thereby contribute to braking. This paper is based on the work done over the NITK Racing Formula Student Car to capture the drag force by changing the angle of attack of the rear airfoil while braking. On application of brakes, the aerodynamic wings present at the rear is adjusted to corresponding angle of attack where the drag created is maximum. A study has been done to find the amount
Cars are something that almost every person has or will use in their everyday life or need to use their car to get to and from work or school everyday. Well in this paper you will learn about what technology has done to change the Automotive Industry as well as your everyday life. This paper will be focusing on the Technologies inside of the car, along with the Technologies that keep you safe and also a little bit about Self-Driving Cars. So fasten your seatbelts while you are reading this paper.
In a little over hundred years since automobile took hold of most people’s imagination, technologies design to make acceleration faster and reaching higher speeds have evolved. Despite charges, turbo charges, twin turbo charges or NOX, there are limits, which cannot be greater by land-based vehicle in terms of speed. Not the same can be said about the rather unseen parts of the automotive evolution. The only limitation to them is in connection with the human body ‘s ability to withstand rapid decelerations. It would be a lot easier to stop a car then to make it go faster otherwise. Whether they come in form of drum brakes or as disk, the brakes have been the horsepower’s companions throughout decades, each pulling
They're fast, too -- on a 65.5-foot (20-meter) track, the cars can cross the finish line in just over a second, traveling at nearly 70 miles per hour (112.7 kilometers per hour)! But even with something to create motion, aerodynamics and weight still make a huge difference.” In order to test and race your dragster car you would need a finish line and of course the car, the car is connected to a machine that blasts out your dragster car and the way to make it to the finish line faster than your opponent is by having a car with less mass.
The Physics of NASCAR by Diandra Leslie-Pelecky: How can a car going 190 mph operate with precision? How can race car drivers walk away from disastrous crashes? The author, a physicist, caught a NASCAR race on television and wondered those same things. In The Physics of NASCAR, Leslie-Pelecky explores the science
Probably the most infuriating argument for an auto enthusiast is when someone ignorantly implies that the drivers are in no way athletes. A driver however must undergo an extensive amount of training, for visceral preparedness. While in the cockpit, the drivers depending on their flavor of driving can withstand extensive amounts of exhaust fumes and tire smoke, to having the need for a cool jacket, a shirt with tubing to pump ice water through it, to keep core temperatures down. In Formula 1, a driver must undergo up to 3.5 times gravity forces of sustained cornering force, meaning if a driver weighs 100 kilograms then they will feel 350 kilograms of lateral force, also called cornering force.
Our most recent Formula One cars are designed with a single seat open wheel racer. They are built mainly from carbon filter composites. In our last season cars were powered by 1.6 litre turbocharged v-6 hybrid engines. Many of these were Ferrari, Renault and Mercedes Benz. Most racing teams are cautious giving out information about their engine, car and performance. There are technical guidelines that the Formula 1 engine will put around 600 horsepower with hybrid drivetrain, this is in addition to the 160
NASCAR, IndyCar and Formula 1 have multiple factors that are similar or different, such as how the cars are set up, how the sports have evolved, and how the races are. There are various types of cars that people drive that are different to each other in unique ways. Furthermore, the ways that Motorsports increased their safety and evolved as a sport is similar to how everyday cars evolve. Safety concerns or crashes happen, causing inventors to create things that will save lives. Additionally, as time goes on, new features will be added to cars, like how the automotive sports evolved. The rules and regulations for these sports are like the laws set in place so that others are kept safe. Also, these sports give a picture of what futuristic cars
The balloon powered race car will be powered by the balloon. The balloon will be blown into and the straw will be the source of the air going into the balloon and then pinched so there is no release of air, then release the air, measure the distance and speed of the car when air is released. This uses the three Newton laws and they are when an object is at rest it stays at rest and an object is in motion it stays in motion in a straight line at constant speed unless acted upon by an unbalanced force, the next is the acceleration of an object depends on the mass of the object and the force applied, the last is every action there is an equal and opposite reaction.
Over the last 136 years stuntmen have done some crazy things with cars. Car stunts can involve racing, peeling out, sliding, jumping and even flipping a car in 100 different ways. As winch and CG technology continues to improve, car stunts that were once considered impossible have become expected and
Nascar is very well known American auto racing company, especially for its stock-car racing, and it stands for National Association of Stock Car Auto Racing. Nascar hosts many races such as the Daytona 500, Richmond Raceway, Kansas Speedway, and plenty of other races. All these races consist of 200 laps or more (2). The audience may not realize it, but the races, the drivers, and the cars have a lot of mathematics involved. For instance, a driver may have to calculate, instantly on the spot, how much their speed should be reduced when performing a sharp curve during the race in order to not lose control of their car and crash. Along with that, race car drivers design their own cars, measure their car’s average speed, calculate instantaneous
According to “slighshot” it is very clear that speed is a major requirement in racing that was presented by car. It is also observed that different racers having different speed limits and driving expertise and this makes car racing to be an interesting sport, for both the participants of the races and the spectators who really enjoyed to be part of the race. Individual with innate desires of car racing started purchasing many cars and from the video they are seen assembling in various places to take place in the car racing activities. Mechanics also had a
To those unaware, racing demands much more than driving fast to win. As far as responsibilities go there are quite a few, to say the least. 2. They include getting around the track as fast as possible, knowing how and when to properly accelerate/decelerate,
The name may not sound familiar, but Sebastian Vettel is the best Formula One driver thats driving today. Surprisingly, he is the youngest person to do this kind of racing since it started back in 1950. Coincidently, Formula One racing is a lot like NASCAR except the cars look different. Now, it is a popular sport around the world but not as popular here in America and that’s why a lot of people here don’t know a lot about this fast paced sport. In the last three years, Sebastian has won four world championships and could own a fifth next year. Also, he started racing at the age of seven by driving in go-kart races. There are a lot of racing legends when it comes to Formula One, but Sebastian is in a league all his own. When
Cars are meant to take you places, but sometimes you can’t get there on time. There are over 88.1 million cars sold in 2016. 16.1 million of those are sold in America. Mercedes-Benz E-Class, Lexus RX 350, and Toyota Prius are in the top 10 most popular cars in America. When there are tons of options of cars to choose from, it’s impossible to know which car will be the fastest of them all. This experiment will be done to prove whether the distance between the wheels matters or not. It will help car manufacturers know the best way to make a car.
The average driver doesn’t think about what keeps their car moving or what keeps them on the road, but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in
