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.
A “rake” means the rear of the race car is higher than the front. This results in the car’s body acting as an airfoil, and produces downforce for the entire vehicle. The special design of the underbody allows an area of low pressure to produce under the car. This results in the car being sucked toward the track by the passing airflow. References Aird, Forbes.
In order to gain a complete understanding of the physics that affect a car, it is necessary to conduct a study that examines all the aspects of physics in regard to acceleration, stopping, aerodynamics, speed, velocity and the list goes on. This paper has addressed the physics of what makes a car move and some of the forces that exist when a car is moving. Kinetic energy and friction play an important role in the movement of a vehicle. Similarly, drag will affect the movement of a vehicle through the surrounding air and is measured as the coefficient of drag. Lastly, the mass of an object times the velocity of the object will equal the momentum of the object.
Anthony Vaccaro Dr. Post Aero 315 25 February 2018 Aerodynamics of Race Cars Aerodynamics is extremely important for the high performance of race cars. A simple change on the angle of spoilers can make the difference between winning and losing. Functioning at such high speeds, race cars are constantly susceptible to large amounts of drag due to the velocity the vehicle and the ever-changing airflow around the car. Manufacturers across the world are constantly performing numerous tests with wind tunnels and other medians to minimize drag, and maximize the ability of a race car to speed smoothly through turbulent air. One must fully understand the aerodynamic concepts and processes at work when a race car speeds around the track, in order
The Bernoulli Effect states that the pressure of a fluid, in gaseous or liquid state, varies inversely with speed or velocity and a slower moving fluid will exert more pressure on and object than the same fluid moving slower (Yager). The goal of car designers is to make the air passing under a car move faster than the air passing over the car. This causes the air passing over the car to create more downforce than the air passing under the car creates upforce creating a force additional to the car’s weight pushing the car to the road. Large amounts of downforce are needed to keep light cars grounded at high speed and keep to cars from sliding around turns at high speeds. The Venturi Effect is also an important in aerodynamic design.

First gear is found to the far upper left, and is used to get the car moving from a stopped position. Down left is second gear, used for speeds up to twenty-five miles per hour. Third gear is located upper middle of the panel, used for speeds from about twenty-five to forty miles per hour. Fourth gear is found at the lower middle and would be good for between forty and fifty miles per hour. Fifth gear is found to the far upper right, and is used for higher driving speeds such as on the freeway.
Harsh weather conditions make it difficult and dangerous for people to drive, however, the car’s ability to drive through inclement weather “frees the user’s time, creates opportunities for individuals with less mobility, and increases overall road safety” (Bose 1326). With all the technology and software in the car, it can “improve road traffic system[s] and reduces road accidents” (Kumar). One of the purposes for creating the driverless car was to help “make lives easier for senior citizens, people with disabilities, people who are ill, or people who are under influence of alcohol” (Kumar). It can be frightening to know that that we share share our roads with drivers that could potentially endanger our lives as well as other people’s lives. How can people not feel a sense of worry when “cars kill roughly 32,000 people a year in the U.S.” (Fisher 60)?
Adaptive Cruise Control By Siva Kumar Raju M.Tech- Automobile Engg. A2326213005 Cruise Control .Cruise control is a system that is used to control the speed of a motor vehicle automatically. The system takes over the acceleration of the car to maintain a steady speed as preset by the driver. Need for Cruise Control .Reduce the risk of accidents. .Improve safety.
This is shown when the car hits the object it causes the car to slow down or completely stop (1). The crumble zone would protect the driver because all the energy has been diverted around the car, instead of the one spot. As a result of the cars mass and its acceleration, the force can be calculated (2).
