Mathematics is found everywhere in life and work and auto racing is

no exception. There are many applications of math in racing.

The purpose of racing is to win and in order to do that there must be a lot of

math involved. If you don’t use math and use it correctly then you will not win.

Mathematics is involved in racing in two ways, the car setup and scoring an

measurements. The car setup involves tire pressure, down force, wedge,

aerodynamic Drag, camber, track bar and valance. The scoring system also uses math.

In addition to scoring math is also used to measure different racing related

subjects such as car weight, gas mileage time interval, qualifying, and the track

characteristics.

Tire pressure is used as a setup tool that is akin to adjusting spring rates in

the vehicles suspension. Increasing the air pressure in the tires raises the spring rate

in the tire itself and changes the vehicles handling characteristics. In order for

optimal performance the teams must know the proper p.s.i ( Pressure per square inch)

for a certain tire on a certain track for a certain air temperature.

Math is also used in measuring the “downforce.” Downforce is the air pressure

traveling over the surface of the car. This air pushes the car downwards which creates

the term downforce. The greater the psi the greater the downforce which creates better

tire grip for higher speeds through turns.

Wedge is another racing term that relies on math. Wedge refers to the relationship

from corner to corner of the weight of the car. The weight on any corner of the vehicle

affects the weight of the other three corners in direct proportion. The wedge determines

how the car handles by either stiffening the wedge or loosening it up.

Aerodynamic drag is another math related racing factor. A number that is a

coefficient of several factors indicates how well a car will travel through the air is the

aerodynamic drag. Teams use specific tests to determine how to achieve the least amount

of drag on the car in order to obtain the fastest speed possible.

Math is involved in the camber of a tire which is also very critical in creating

the fastest car possible. Camber is the angle at which a tire makes contact with the track

surface. The camber varies from tire to tire dep...

... degree of the angle of the track, usually the banking is the

steepest in the turns. The banking can range from 0 degrees to 34 degrees which is

significant to the team when preparing for a race.

Math is very important in the world of racing. In order to be the most

competitive teams must know how to use math and use it correctly.

Incorrect calculations can cause dismal performance, fines and be dangerous

to the driver. Due to these reasons race teams accept no error in calculations

and always make sure to use the math to their advantage. Math is used in different ways

in racing. Math is used to determine the proper setup of a car and is used to determine

the scoring and measurements of racing subjects. The car setup involves math in

the tire pressure, downforce, wedge, aerodynamic drag, camber, track bar and the

valance. Math is used in the scoring to determine how many points a driver receives each

race and is used in measuring the car weight, gas mileage, time interval, qualifying and

the track specifications. All of these are just some of the many examples of how math is

relevant in all areas of life including auto racing.

## Physics of Car Racing Essay

- This paper is a look at the physics behind car racing. We look look at how we can use physics to select tires, how physics can help predict how much traction we will have, how physics helps modern cars get there extreme speed, how physics lets us predict the power of an engine, and how physics can even help the driver find the quickest way around the track. Tires are the most important part of race or any car for that mater. (Physics of Racing) After all they are the only thing that is contact with the ground....   [tags: physics sport sports racecar car race racing]

## The Racing Twenties Essay

- While automobile racing is a sport that is firmly ingrained in American culture now, it wasn't always the mature sport we see today. The motorsport that tests a driver's precision, reflexes, and car is only around 110 years old. There is a decade in racing history that many NASCAR fans never think about, and that is the 'Roaring Twenties'. The 1920s really laid the groundwork for the fierce competition seen in the 1930s with innovation in car technology, skilled racing teams, and new championship events....   [tags: Auto Racing]

## Essay on The Use of Similes in Auto Wreck

- The Use of Similes in  Auto Wreck           In his poem Auto Wreck (p. 1002), Karl Shapiro uses carefully constructed similes to cause the events he relates to become very vivid and also to create the mood for the poem. To describe the aftermath, especially in people's emotions, of an automobile accident, he uses almost exclusively medical or physiological imagery. This keeps the reader focused and allows the similes used to closely relate to the subject of the poem. Three main similes used are arterial blood, tourniquets and cancer....   [tags: Auto Wreck]

## Horse Racing : The Ethics Of Winning Essay

- Horse Racing: The Ethics of Winning Even though tensions rise between the ethics in sport and the ideas of winning, families identify accomplishment in the bond between hobbies and the good life, as horse racing is a favorite past-time. Although desiring to win compromises the conduct and character of the owner, trainers, jockeys, and horses, many fans remain uptight toward betting on cheaters while taking them at face-value. While articles, periodicals, and congressional hearing testimonies about the sports culture of horse racing feature opposing strands of greed and reveal the binary just/unjust, the more interesting ideas come from the differences in the tone of voice, which show a patte...   [tags: Horse, Horse racing, Whip, Jockey]
