Abstract - The force offered by the driver of an automotive in navigating the vehicle along the road is transmitted through the steering wheel through the steering system up to the front wheels. Manual or hydraulic mode is utilized to turn the wheels. This dissertation work aims to focus on the ‘universal joint’ also called the ‘yoke’ .The component have two halves that pair to effect a flexible axial joint while accommodating misalignment. Forces are transmitted through the ‘spider’ or the ‘web’ within the two halves. This work attempts to evaluate the strength of the joint to avoid failure. Besides, the scope for mass reduction in realizing a lighter component shall also be investigated using the methodology for ‘Topology Optimization’ while engaging `Altair Hyperworks - OptiStruct’ in dealing with problem. Mathematical treatment is offered to understand the extent of forces to

author build car with suitable cockpit to evaluate steering response curve and proper physical behavior of the car to give realistic experiment. with this setup author has conducted experiments on different linear and non linear steering response curves to find out suitable steering system for passenger car. After study author come on conclusion that linear response curve with a high steering ratio like 1:45 or 1:60 lead to the least amount of lateral velocity of the car at speed of 200km/h and this will lead to complete crash due to loss of control on

The faster the wheels spin, the faster the car will go. Our project requires our car to go at least 3 meters. Our initial trials were successful because our car went 7,8, and then 9 meters. The car went 7 meters in 8 seconds with a speed of 0.875 m/s. It went 8 meters in 10 seconds with a speed of 0.8 m/s. It finally went 9 meters in 12 seconds with a speed of 0.75 m/s. It is what makes the wheel spin instead of just sliding on the ground.
A connecting rod subjected to an axial load F may buckle with x-axis as neutral axis in the plane of motion of the connecting rod, {or} y-axis is a neutral axis. The connecting rod is considered like both ends hinged for buckling about x axis and both ends fixed for buckling about y-axis. A connecting rod should be equally strong in buckling about either axis [8].
If I was the programmer, I would instruct the vehicle to continue on its intended path, regardless of the situation. If, after making a turn, I noticed a group of people in the road, I would hope that the car would make an effort to stop. However, I would not allow the self-driving car to swerve into a wall or a sole pedestrian. By changing the path from which the car originally intended to go, you make the car become a leader in this situation, not just a bystander. In order to make the car swerve, it would need an external factor to deviate from the original design. This decision carries responsibility as well. There is a difference between the vehicle choosing to swerve into a wall and choosing to hit the group of people. In fact, the vehicle would not be choosing to hit the group of people at all, the group was in the vehicle’s way.
But there appears to be an escalating problem with SUVs. As Americans thirst for more of the power and comfort they provide, we are refraining from using proper caution while driving SUVs. These vehicles provide a false sense of security for drivers when faced by inclement driving situations. Because of the feature of four-wheel drive, drivers automatically assume safety. These vehicles are also very dangerous to the other vehicles on the road. By observing the trends and facts one will see that Sport Utility Vehicles are a major cause of the increasing danger on the roads today.
Ever since the invention of the automobile, numerous efforts have been employed to try and improve its safety features. Judging by the current statistics, one could argue that driving has so far turned out to be a risky business. In actual fact, people of all ages and social status are considered to be in control of lethal weapons whenever they have to drive. According to the National Safety Council, it is estimated that more than 41,000 people lose their lives in road accidents annually and no less than 2 million more suffer from serious life threatening injuries (2009). Furthermore, it is estimated that at least 50% of the people killed in road accidents is as a result of their failure to adhere to safety measures such as wearing seatbelts while driving, driving under the influence, or careless driving (Ingalls, “Defensive Driving Strategies”). As an effect, huge losses occur with respect to life, injuries sustained, and damage to property.
On a first reading, The Driver's Seat may seem to be a novel about an obsessional fear, of everything except death, held by the central character, Lise. Yet on a closer second reading of the text it becomes apparent that the novel is actually about Lise's strict conformity to the Christian faith and her constant will to die. To a person knowledgeable in the field of basic psychiatric function, it is obvious that Lise is suffering from some form of mental illness, most likely a variety of depression. She frequently experiences suicidal thoughts and displays symptoms of this throughout the novel. Her main concern during the narrative is finding someone that will kill her. An in-depth reading of the text could lead the reader to believe that the reason for this search is because Lise's underlying commitment to the Christian faith will not allow her to take her own life.
Driving has been around for just over 100 years, but the first thoughts of physics has been around since 400 BC (to be edited ). Driving safety implications have been discussed and improved over the decades as technology begins to leap ahead of its time. According to physician; Newton, there are three laws of motion that is now used in everyday life to try and help prevent deaths due to driving implications. The first law is “An object at rest will remain at rest unless acted upon on by an unbalanced force.” The object, or Car is in motion continues its motion with the same speed and in the same direction unless acted upon by an unbalanced force. The second law is “Acceleration is produced when a force acts on a mass.” While the third Law of Motion is : “ For every action there is an equal and opposite re-action.This means that for every force there is a reaction force that is equal in size, but opposite in direction.”
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.
Before the advent of the automobile, buggies were typically propelled by one or more horses. Even with the first automobiles there was a need for a drive system, though, since those horses were no longer there. One thing that has remained common to every car is a motor and transmission system of some sort, but what varies greatly between cars is what is between the transmission and the wheels, also known as the drive train. There are many different styles of drive trains, each with their own advantages and disadvantages.
This essay is to inform you about certain aspects of driving. In this letter I am going to talk about the effect of response time, a safe following distance, how the stopping distance depends on speed, how to decide what to do at a yellow light and how you have to change your speed around a curve. In the next following paragraphs I will explain each of the topics that I have listed and I will give you a better knowledge of how to be a safer driver.
In my undergraduate years, I have acquired a strong background in the fundamentals of basic mechanical engineering, having studied subjects such as Strength of Materials, Thermodynamics, Fluid Mechanics, Heat and Mass Transfer, Design of Machine Elements and Automobile Engineering. Whilst pursuing my diploma & degree courses, my interest for Automotive Engineering grew even more having learnt more on the different types of internal combustion engines, their configuration and importance. However, what I lacked was a practical understanding on these core areas of Automotive Engineering. To gain a better understandi...
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 reasonable control.
Good stability and handling is achieved with a combination of suspension, steering, acceleration, brakes and weight distribution.
Law two can be used to calculate “the relationship between an objects mass (m), its acceleration (a), and the applied force (f) is F= ma.” This formula is used in all of the above components in the car.
