Origins tires were invented in 1888 by a scottish veterinarian named John Boyd Dunlop. these were the first pneumatic tires. he attached a rubber tube around his wooden bike wheel and he covered the contact patches with thick canvas.
There was a large desire for tires because the faster the object gos the greater the chance there is for wheel slippage and all roads at first were dirt. tires also soften the bumps on the road, having wooden wheels is all around less efficient and won't grip the road like tires do.
Different kinds of tires are better at different tasks, for example; there are 4 different tires: racing, mudding, street, all terrain and commercial tires. street tires are built to be driven on the street because of their treads, they are specifically designed for gripping the road, not just dry pavement but they also work on wet pavement and moderately well on icy pavement. all terrain tires treds are basically thick street treads that do well off road better than street tires but not as well as mudding tires. commercial tires are are very sturdy and meant for heavy loads, they can survive running over more without getting a air leak than regular tires and are pretty closely related to all terrain tires. and then there are racing tires, racing tires, depending on the type of racing, don't have tried at all and are often referred to as slicks, they Slicks are racing tires with smooth surfaces. The most fundamental method of providing mechanical grip in a race car is to put as much surface area of the tire in contact with the road, or track surface, as possible. Because slicks have no grooves, they have a larger contact patch, or footprint, and provide optimal traction.

... mud to snow or even just pavement, but without them we wouldn’t have been able to advance in our automotive technology. Tires make it possible to drive and for “a piece of rubber” stuck to the outside of your rim, they’re pretty important. So take care of your tires they’re there for a reason and you can’t drive without them.

George Washington Gale Ferris Jr.(14 Feb. 1859-22 Nov. 1896) was a civil engineer/ construction engineer who invented the Ferris Wheel. George Ferris was born in Galesburg, Illinois to farmers, George Washington Gale Ferris Sr. and Martha Edgerton Hyde Ferris. He lived with his 4 sisters and 2 brothers. When Ferris 5 years old his family sold their farm and headed toward San Jose, California. Unfortunately in the middle of their journey they ran out of money and had to settle in Carson City. In Carson City they made a ranch and Ferris helped his father farm for 9 years before going to California Military Academy in 1873. In 1876 he graduated and applied for the Rensselaer Polytechnic Institute in Troy, New York to study civil engineering.
The very first snow machines had tracks with very bad traction. But you must realize that they weren't driving in the same conditions snowmachines of today can handle. Old machines were limited to readily used trails and very little powder. The tracks used on the old machines looked like the one shown in the picture below. The traction, the little raised bits of rubber, was minimal and the tracks weren't very economical either.
It is what makes the wheel spin instead of just to slide on the ground. If there were to be no friction such as ice the wheels would not spin and the whole car would just slide on the ice. With all the friction the car could not move at all. With the right amount of friction which we had to apply to the car the wheels will move and the car will go at a fast constant speed. This way we used friction in the right amount and it helped our mouse trap car go the distance and meet the requirement of one set of free spinning wheels. This is how friction is used in the mouse trap
Suitable for the men and younger: Silverstone tyres are suitable for the men Youngers person. It’s because tyre is more suitable to the men and younger. It can attract consumers to buy their product because of the quality and cars is related with the Youngers or teenagers and men. It is the strength to the Silverstone because teenagers that have their own income and easily to buy the car tyre for their cars.
From both foreign countries and the United States, complaints state that the tires lose their casings when traveling at high speeds. The tire maker claimed it knew nothing of the tread problems until late July, yet consumers have warned the company since the mid 1990’s (Nathan). It also stated that the complaints it finally received did not raise any “red flags” because in relative terms, few tires had failed; less than one in every 10,000 of the 47 million ATX, ATX II, and Wilderness AT tires produced since 1991 have failed (Nathan). Most of the recalled tires came from the Decatur, Illinois plant, the main concentration of the investigation. The company claimed that a workers’ strike at that plant in the nineties, when replacement workers made the product, caused most of the problems.
It took new technology and some brilliant minds to bring the pieces together to form the luxury of nice, smooth roads that we have today. They had to make some of the biggest engineering breakthroughs of their time. The creation of asphalt as a byproduct of oil refining, for example, now allowed the creation of roads that were smoother to drive on and less harmful to the environment. Before this discovery, asphalt was mined and stripped from underneath the earth’s surface.
Many of us have gotten rock chips, but how many of us understand how those pesky rocks hit our windshield? A common misconception is that the car in front of us throws rocks "backward" and hits the following car's windshield. A rolling tire cannot throw a rock backwards. A tire is a rolling object, thus every point along the tire is moving forwards. There is no force going in a backwards direction. Only direction part of a rolling object can go is a combination of up or down, and forward.
I can tell you right now these aren't going to hold a patch. They're shot through." (page 40). Mattie was exceptionally nice to Taylor and told her to come inside and have some coffee. After drinking a cup of coffee and giving Turtle some juice, Mattie came up with the idea that Taylor could work for her. Taylor, being the one who doesn't like tires in the first place, accepted the generous offer, but went almost nuts with the huge tire wall that surrounded her.
The main advantage of the track over the wheels is that it can distribute a very large force over a large area. That means that instead of applying all the force on little area where wheels touch the ground, it applies it over the whole area of the track.
As the distristed driver finished putting in the last lug nut he ponders on how easy changing a tire really is, you just need someone to show you how to go about doing it. Completing this task will look like a fully intact, and functional tire. This driver is now prepared to not only change their own tire, but help others that are in
Whereas the Russian Mountains is usually credited as the first wheeled coaster, the Switchback in 1784 at St. Petersburg is perhaps more worthy of the crown. Carriages in grooved tracks traveled up and down small hills powered by the height and slope of the initial descent. Almost 50 years later, the first tracks were laid for the American predecessor of the roller coaster, the Mauch Chunk Switchback Railway in Pennsylvania.
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)
Most people though aren't out there trying to lose a tire on purpose. If you're like most people you want to drive on your tires as long as conceivable. But should the unexpected happen some long lonely night and the world seems to want you to simply stare out at the stars on the dark moonless night in the middle of nowhere, it would behoove you to have a slight understanding of the workings of your spare tire, wherever it may be stowed, since cell phones don't always work everywhere. At this point fate might be telling you to slow down. Alas, this isn't usually the case, so give heed, and have some advice.
Created because California surfers were looking for a form of entertainment, something to do while there were no waves. No one knows who made the first board, but it's known that many people had similar ideas of skateboards. Many started with wooden planks, wooden boxes, boards and would attach roller skate wheels to the bottom. In 1959 Roller Derby produces the first skateboard with metal wheels, which then lead to a evolution and out going experience for society. By 1963 skateboarding was all the rage, popularity of the sport was ats its peak, then suddenly started to fade. By the 1970’s urethane wheels were invented and skateboarding picked back up with new styles and inventions to improve upon skateboarding. In the 1980’s and the 1990’s skateboarding continues to grow and establish a subculture. In the 2000’s many cities have built many skate parks and camps learning
