CHAPTER: 1
INTRODUCTION
There are various kinds of forces which act on an automobile vehicle while driving. These forces are responsible for the instability of the vehicle and they also cause rollover of the vehicle if there is more steering angle when it is running at high velocity.
• The types of forces acting on an automobile are given below:
i. Inertial Forces ii. Centrifugal force iii. Centripetal force iv. Acceleration force
v. Braking force vi. Aerodynamic force vii. Traction forces viii. Steering forces
i. Inertial forces:
• Inertia is a property of an object to resist the change in motion. In automobiles inertia is the resistance to change the direction or velocity of a body either at rest or in motion. Further briefly it is related

The magnitude of acceleration: The acceleration magnitude is the difference between the initial speed and arrival speed of the vehicle.
b. Mass of vehicle: If the mass of vehicle is less, then load on the vehicle is reduced. So acceleration force is also dependent upon the mass of vehicle.
v. Braking Force:
• This force is caused due to sudden deceleration of vehicle. When sudden brakes are applied on the vehicle, deceleration force is caused on the vehicle which reduces the stability of passengers inside the vehicle.
• The main factors influencing the braking force are:
a. Mechanical Braking: This force is caused when brake is pressed through brake pedal, which slows down the vehicle. It creates a loss of pure energy which is used to move vehicle.
b. Engine braking: Engine braking or compression means shifting to a lower gear to slow down the vehicle. Like mechanical braking, it creates loss of accumulated energy and also causes a force to passengers sitting inside the vehicle. vi. Aerodynamic force:
• This type of force depends on the dynamic pressure acting on a vehicle. This force is proportional to the square of speed. At very low speeds, this force is negligible. At normal highways, this force may contribute a force equivalent to about 0.03 g
Traction is the grip a tire has on a road or track. 7. Centrifugal Force- Centrifugal force is a natural law that helps a car to safely come out of a curve and into a straight path or road. 8. Centripetal Force- Centripetal force means center seeking force it is necessary for your car to move in a circular motion.
Unit 1 & 2: Acceleration When Lightning Mcqueen was on his way to visit Smokey, He saw the sign to Thomasville which had a picture of Doc on it when he was a racer because they passed by it at first, Mcqueen asked his truck driver to back up. This relates to acceleration because, in order to change directions, the truck driver had to come to an abrupt stop which increased the acceleration. Because the amount of time that it took to cease the speed was halved, the acceleration doubled. Unit 3: Newton’s 3 Laws While Lighting Mcqueen and his trainer Cruz were at the Thunder Hollow track, which was in the shape of figure 8, there were several cars in motion. However due to the law of Inertia, which states an object in motion stays in motion unless
Recently Get A Fifth Wheel Trailer? Follow These Tips For Driving With It Getting a fifth wheel trailer for the first time can be an exciting thing, especially for those starting retirement and looking to travel a lot more. Unfortunately, the practicality of driving with a fifth wheel trailer can be a bit daunting if you have never done it before. Before you set off on your first excursion, consider these tips for driving with your fifth wheel trailer.
Group and Topic The group was composed of Korbett, Emanuel and Joshua. The primary duty was to research various accelerometers that were designed for use in sports without helmets such as volleyball, soccer and boxing. Background The Project as a whole is focused on concussions.
By taking a hands off of the wheel, it can put others in danger. Some people think that driving without hands on the wheel is cool. But it is extremely dangerous to others. By the shape of the road, by how strong the wind is, if the car's tires aren’t balanced, or the car is not aligned correctly. It can pull the car to the side or the middle of the road.
Chapter 4 Elasticity What is elasticity? Elasticity means the ability of an object to resume its normal shape after being stretched, or the ability of something to change and adapt. Some examples of elasticity is a bungie cord and rubber bands. Then there things that can be the opposite of elastic; which is called inelastic.
For example there is centrifugal force which is what is used for the duration of the time that you spend cradling the ball. Centrifugal force is the outward force on a mass when it is rotated which causes it to be more difficult for something to move and change location. An example of this is when you are spinning a bucket of water around on your arm and none of it falls out because you are going so fast. This is because the outside force, which in this case the act of cradling, is applying more pressure on the lacrosse ball from the outside of the net than gravity is causing on the inside of the net which results in the lacrosse ball staying inside of the net of the lacrosse stick. Newton's first Law of Inertia is put into play because when you have control of the ball the only thing that can change that is either a change of gravity that can be caused by the lack of centrifugal force due to lack of cradling, or another force which in this case would happen to be another player that is applying pressure to you changing your force and affect the force on the ball.

Describe explicitly for both the hanging mass and the PAScar what the velocity and acceleration will be before and after the string is cut.
A flat tire? Tire blow out? These are situations, which warrant considerable sense to stop the vehicle at a slower pace towards the sides of the road away from the ongoing traffic. Regularly check the tires and maintain them with proper pressure.
1) If Toyota is not the cause of unintended acceleration, why was it blamed for it? Last quarter of 2009 The leading Toyota motor corporation has faced disaster in their products because of unexpected quality issues, so to overcome in their fault they issued huge formal recall of their products all over the world. In this period, Toyota recalls around 5.2 million cars for floor mat problem and 2.3 million cars for accelerator pedal problem. For both case around 1.7 million cars and following this Toyota amplify 1.8 million cars from Europe and 75,000 from China (almost 9 million cars recall all over the world within a month).
Self-driving cars have been discussed for many years now, and they will be used for our society everyday use in the future. Some of the possible causes of self-driving cars are distracted driving, drunk driving, and texting while driving. Many car companies, colleges, and universities have been involved along with technology and car experts. Some of the possible solutions to this problem are to help reduce traffic congestion, deaths, and fatal car accidents. Self-driving cars are new emerging technology, and it will be used for our society everyday use in the future.
The regenerative braking system on the model offers an even greater thrust of electrical power derived from braking and coasting. Hybrid cars can rightly be termed the transportation machines of the future. Thinking of
Since the driver is not actually maneuvering the car if an accident happens, who is to blame for this situation, is another essential issue. You cannot put the blame on the car, as it is an object, and even if it rules by a performant
CHAPTER 1 INTRODUCTION 1.1 ABOUT THE CAR A Formula Student car is an opened wheeled race-car designed and fabricated by university level students to compete at global level against other universities. The students involved in such projects conceptualize, design, fabricate, test and race a single seated, open-wheel Formula Style race car. The design of such a car aims at enhancing dynamic performance while maintaining the safety and following the guidelines lay down by the governing body. 1.2
The Automobile business is a blend of organizations and companies engaged with the plan, advancement, assembling, promoting, and offering of vehicles. External environment is outside influences which has an effect on the industry. The environment factors help the industry to go through vast changes. Emergence of new competition have huge impact on vehicle development and design. Advancement of technology has helped the industry to use more high-tech driving capabilities.
