The Physics Of Nascar

  1. 1. By Sandra Cash
  2. 2. <ul><li>Okay NASCAR isn’t just someone driving at a really fast speed and if that’s what you think about NASCAR then I hope that this power point shows you that it’s not! </li></ul><ul><li>There are three categories The Sprint Cup, The Nationwide Series, and The Craftsman Truck Series. </li></ul>
  3. 3. <ul><li>The Sprint Cup is the sport's highest level of professional competition and is home to the world's top racing talent. The season is ten months long and it has 36 races. Also The Sprint Cup is the one that you have more likely have been seen on TV because it is the sport’s highest level, so it is the best of the best which makes it interesting. </li></ul>
  4. 4. <ul><li>The Nationwide Series also known as the Busch Series is the second-highest level of professional competition. This is also considered a stepping stone to Sprint Cup Series. </li></ul><ul><li>Craftsman Truck Series featuring tough, rugged, American-made trucks, has 25 races a year. This series is a favorite of those who like trucks. It is one of the three national divisions of NASCAR. </li></ul>
  5. 5. <ul><li>NASCAR teams must consider at least three physics concepts: friction, downforce and aerodynamics. </li></ul><ul><li>The tires are very important to NASCAR because they provide the right amount of friction so that the tires will stay on the track while going really fast. The car takes very fast turns, and you don’t want a tire to explode on you! </li></ul>
  6. 6. Unlike the tires you use on your car NASCAR has special tires that they use. Few factors play a more critical role in NASCAR races then the tires. Inflation pressures, tire wear and tire balance can all have a tremendous effect on a car’s performance. Tires must be changed quite often throughout the race as they wear down. These cars are going so fast that the tires start to melt because of all the friction. In NASCAR a NASCAR team will use between 9 to 14 sets of tires a race depending on how long the race is.
  7. 7. <ul><li>These race tires have a safety feature: a tire within a tire. This allows the car to return to the pits, even with a flat. Most of the teams remove the air from the tires and replace it with nitrogen. By using nitrogen instead of air, the teams have more control over how much the pressure will increase when the tires heat up. Compressed nitrogen contains less moisture than compressed air. When the tire heats up, moisture in the tire vaporizes and expands, causing the pressure inside the tire to increase. Even small change in tire pressure can noticeably affect the handling of the car. </li></ul>
  8. 8. <ul><li>The body of the car is important but not as much as the tires this is because the body only has to do with the looks, and downforce. Downforce is an aerodynamic force that tends to press the cars tightly against the ground, allowing the tires to grip the track with more force. This helps the cars go around the tighter turns as quickly as possible. </li></ul><ul><li>The cooling system is also very important because you don’t want your engine to overheat. If the car overheats that can cause a lot of problems. </li></ul>
  9. 9. <ul><li>NASCAR teams build two types of cars. They build cars for the short tracks, like Bristol Motor Speedway in Tennessee, where top speeds are lower and turns are tighter. They also build cars for the super-speedways, like Talladega in Alabama, where top speeds are higher but engine power is limited. </li></ul>
  10. 10. <ul><li>Short-track Cars The goal in designing a short-track car is to create as much downforce as possible. Downforce is an aerodynamic force that tends to press the cars tightly against the ground, allowing the tires to grip the track with more force. This helps the cars go around the tighter turns as quickly as possible. </li></ul>
  11. 11. <ul><li>Super-speedway Cars On the super-speedways, the track is much longer and straighter and the banking is high, allowing cars to maintain a high speed all the way around the track. The goal in building a car for super-speedway tracks is to reduce drag as much as possible. These tracks require the use of restrictor plates that reduce engine power from about 750 horsepower (hp) to 450 hp. </li></ul>
  12. 12. <ul><li>The thermostat is a valve that either restricts or allows the flow of coolant from the engine to the radiator. When the engine is cold the thermostat stays shut, confining the coolant to the engine only. The purpose of this is to help the coolant to warm up. As the coolant warms, the valve in the thermostat begins to open, allowing the coolant to now flow to the radiator and back to the engine. During normal conditions with a fully warmed engine, the thermostat will allow an unrestricted flow of coolant to the radiator. </li></ul>
  13. 13. <ul><li>Physics are very important to consider in NASCAR. Friction, aerodynamics and downforce are just three physics concepts that are used everyday in NASCAR racing. </li></ul>
  14. 14. <ul><li>NASCAR started as a backwoods illegal race to run moonshine. </li></ul><ul><li>The temperature inside a stock car can reach up to 140 degrees F or 60 degrees C during a NASCAR race. Drivers can lose between five and ten pounds during a race! </li></ul><ul><li>A NASCAR Pit Crew consists of 7 members: front tire changer, front tire carrier, rear tire changer, rear tire carrier, jack man, gas man and the gas catch can man. </li></ul>
  15. 15. <ul><li>NASCAR got it’s name from Red Vogt. Red Vogt thought of the name NASCAR, for National Association of Stock Car Auto Racing. </li></ul><ul><li>Bill France Sr. is the founder of &quot;NASCAR,&quot; and Fireball Roberts and Lee Petty were some of the first drivers of the sport. </li></ul><ul><li>A yellow strip across the rear of a NASCAR racecar signifies a rookie driver. </li></ul>
