Without a differential an automobile is very dangerous and ineffective, it is likely that your automobile will last about half its intended lifespan and will also create huge difficulties in turning. The differential is a key part of an automobile’s drivetrain, it allows the vehicle to effectively maneuver turns and cornering. Different differentials approach the goal of increasing a vehicles maneuverability around corners and in sticky situations with different mechanical approaches; there is an ideal differential for snow and ice, dirt and offroading, and for street driving.
To understand why an automobile needs a differential one must first have a basic understanding of physics and geometry. The driven wheels on a car are the wheels that are given power through the engine and transmission, on a rear wheel drive it is the rear wheel and on a front wheel drive it is the front wheels (How Differentials Work). When cornering a turn the driven wheels of a vehicle go in an arcing path, an arc is part of a circle and because the outside wheel (the wheel opposite the side of the car in which the direction you are turning) is further from the turning point than the inside wheel. Because of the larger distance from the turning point the outside wheel must travel farther than the inside wheel. You must take notice that the equation for speed is distance divided by time, so one can infer that the outside wheel must travel the farther distance in less time than the inside wheel, meaning it must travel faster than the inside wheel, to keep the wheel from sliding and ruining the tire and putting stress on the driven axle (Halderman). There are four different types of differentials that deal with this issue very differently:...

Now To talk about the forces that allow the car to move. There are two main aerodynamic forces acting on any object moving through the air. Lift is a force that acts 90° to the direction of travel of an object. Usually we think of lift when we think of an airplane. The plane travels forward (horizontally), and lift acts 90° to that motion of travel –
That is to say, that the rock at the top of the tire may be going twice as fast as car itself. Similarly, at the point of contact of with the road, the velocity of the rock is 0.
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.”
Driving defensively is key to avoiding accidents. This refers to anticipating hazards and being prepared for them, or driving and expecting the worst. When I was practicing my driving, my dad told me, “When you feel like another driver is going to make a bad move, assume that they will.” Just because it’s wrong for that other driver to cut you off doesn’t mean they won’t do it, so always plan for the worst of things. The main takeaways of defensive driving are:
The issue of whether customers should buy FWD and RWD cars is complex and controversial. Different people hold different ideas due to their drive experience and consumers attitudes. On one hand, lots of people believe that only RWD cars represent Luxury and high-performance. On the other hand, the car made on FWD are much cheaper and popular. However, most of customers are blind and ignorant on it. Many of them don’t even know the automobile layout of their sedan after use it for decades.
The move toward a more aggressively styled and higher riding vehicles have caused unintended consequences and risks. The risks include decreased “drivability”, obstruction of vision, and concerns surrounding safety. Current trends in vehicle design focus on addressing these problems to achieve appealing designs with the best qualities of both cars and trucks, as seen in all the new designs from the Land Rover.
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.
Defensive driving is the act of driving safely while being alert and aware of your surroundings and other drivers. It is the act of driving for yourself and others as well. You cannot be a defensive driver if you have distractions. Whether it be people, music or even objects, you should keep all of these things at bay.. By doing this you will become a better, more defensive driver. When driving it is important to stay focused by keeping your eyes on the road and your hands on the wheel. You should never take your eyes off the road to do anything while the car is in motion, even if it is only for a split second because you could cause a very serious accident. It is also important to check your mirrors before you pull off and use them as you are driving. The only time that you should take your eyes off the road in front of you, is to check the road on the sides of you and in the rear of you by using your mirrors. This is an important factor for defensive driving because it allows you to make safe lane changes and be aware of your surroundings.
It is interesting to note that the ongoing controversy concerning the so-called conflict between Wilhelm Gottfried Leibniz and Isaac Newton is one that does not bare much merit. Whether one came up with the concepts of calculus are insignificant since the outcome was that future generations benefited. However, the logic of their clash does bear merit.
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! Tires work by having a high coefficient of friction. Some slicks have a friction coefficient grater then 1! (Physics of Racing) Typical normal street tires have coefficient of about .5 to .6 . In physics we learned that friction was equal to mew times the normal force. Since race cars are typical much lighter then normal cars, they use tricks to increase the downward force on the tires. Some drag tires run really low pressure, other drag cars tune the car to lift the front wheels to put all the weight on the rear tires. Indy cars use a wing to generate down force, and ventures to suck the car to the ground. (How to Make Your Car Handle)
...ads. The theory behind this is that a non-rotating tire has less traction than a spinning one. The ABS will allow the vehicle to stop faster than when the wheel is skidding and allow the driver to remain in control of the vehicle while it stops. With the technology today, there are sensors attached to the wheels to sense when one wheel is spinning at a different speed than another.
Next, the constant multiple rule is the derivative of a constant times a function, is just the constant times the derivative and It states:
Ever wonder how scientists figure out how long it takes for the radiation from a nuclear weapon to decay? This dilemma can be solved by calculus, which helps determine the rate of decay of the radioactive material. Calculus can aid people in many everyday situations, such as deciding how much fencing is needed to encompass a designated area. Finding how gravity affects certain objects is how calculus aids people who study Physics. Mechanics find calculus useful to determine rates of flow of fluids in a car. Numerous developments in mathematics by Ancient Greeks to Europeans led to the discovery of integral calculus, which is still expanding. The first mathematicians came from Egypt, where they discovered the rule for the volume of a pyramid and approximation of the area of a circle. Later, Greeks made tremendous discoveries. Archimedes extended the method of inscribed and circumscribed figures by means of heuristic, which are rules that are specific to a given problem and can therefore help guide the search. These arguments involved parallel slices of figures and the laws of the lever, the idea of a surface as made up of lines. Finding areas and volumes of figures by using conic section (a circle, point, hyperbola, etc.) and weighing infinitely thin slices of figures, an idea used in integral calculus today was also a discovery of Archimedes. One of Archimedes's major crucial discoveries for integral calculus was a limit that allows the "slices" of a figure to be infinitely thin. Another Greek, Euclid, developed ideas supporting the theory of calculus, but the logic basis was not sustained since infinity and continuity weren't established yet (Boyer 47). His one mistake in finding a definite integral was that it is not found by the sums of an infinite number of points, lines, or surfaces but by the limit of an infinite sequence (Boyer 47). These early discoveries aided Newton and Leibniz in the development of calculus. In the 17th century, people from all over Europe made numerous mathematics discoveries in the integral calculus field. Johannes Kepler "anticipat(ed) results found… in the integral calculus" (Boyer 109) with his summations. For instance, in his Astronomia nova, he formed a summation similar to integral calculus dealing with sine and cosine. F. B. Cavalieri expanded on Johannes Kepler's work on measuring volumes. Also, he "investigate[d] areas under the curve" ("Calculus (mathematics)") with what he called "indivisible magnitudes.
Learning to master driving a manual transmission car has taught me that safe driving is the best driving. When driving stick shift you are constantly moving, looking, listening, and thinking. Learning to balance all this helps you realize how dangerous it is driving stick shift. At any given moment you can be in danger and now you have to add the danger to your already overwhelmed mind. There are many components in learning to drive stick shift but the experience as a whole is worth
One of the most important advantages of owning a car is convenience. It allows you the freedom to go anywhere you want whenever you want. There is no hanging about waiting for public transport to turn up in potentially bad weather.
