  • WheelA wheel is a circular component that is intended to rotate on an axle. The wheel is one of the maincomponents of the wheel and axle which is one of the six simple machines. Wheels, in conjunction withaxles, allow heavy objects to be moved easily facilitating movement or transportation while supporting aload, or performing labor in machines. Wheels are also used for other purposes, such as a ships wheel,steering wheel and flywheel.Actually no one know about who was the author of this invention it is like the fire no one know exactly who cancontrol the combustion but the oldest wheel founded in 2002 has about 5 thousand year I mean 3 thousandyears BCThen the ancient civilizations as the Egyptians, Greeks, romans, were developing different uses for the wheeland also were improving its performanceThe first vehicleswerewooden sleds, and must have beenused bytribesfrom around theworld.Tocarryheavylogswere usedas aroller, and finally built itone piece, tying the logswith woodcrossand tiethe whole thingwithstripsof leather.Then,immediately appear the inventionof the wheel, one of the most wonderfulin history.From thisinvention,was developed all kinds ofland transport.In the transportation, the animals appear because the humans were not strong enough to carry the heavyburdens so they start using dogs, then bull, horses, ox, elephants an all the possible strong animalsAhorseexertingone horsepowercan raise330 pounds ofcoal100 feetin one minute, or 33 pounds ofcoalat1000feet in one minute, or 1000 pounds33 feetin one minute,etc.remember that one meter is about 3 feet.Da Vinci’s Car
  • DaVincis designs for aself-propelled vehiclewere revolutionaryfor its time.His "car" of woodwasdrivenby the interactionof springs withsprockets.Scientists ata museumin Florence builta replicain2004and found it workedasDa Vinciintended.Before the industrial revolution began, was created a machine that works with steam scientific realized that thesteam has the enough power to move thingsEdward Somersetwas an inventor, detailing more than 100 inventions,including a device that would have beenone of the earliest steam enginesThen a Frenchwatchmaker calledNicolas-Joseph Cugnot was a Frenchinventor. He is believed to have built thefirst self-propelled mechanical vehicle, He trained as a military engineerHe experimented with working modelsof steam-engine-powered vehicles for the French Army, intended for transporting cannons, starting in 1765.A steam engine is a heat engine that performs mechanical work using steam as its working fluidBut what was theCoalwhat make it possiblethe coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the 13th century)[1] is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veinscalled coal beds or coal seams this was used to heat the water till its boiling pointThe history of the automobile begins as early as 1769, with the creation of steam engine automobiles capable ofhuman transport but what is and automobileAn automobile, auto car, motor car or car is a wheeledmotor vehicle used for transportingpassengers, whichalso carries its own engine or motor.The word automobile comes, via the Frenchautomobile from the Ancient Greek word αὐ τός (autós,"self") and the Latinmobilis ("movable"); meaning a vehicle that moves itself. The alternative name caris believed to originate from the Latin word carrus or carrum ("wheeled vehicle"), or the MiddleEnglish word carre ("cart") (from Old North French)
  • The innovation of Cugnot was applied for the transport of heavy things, but it was a single model, because itwas extremely heavy and impractical. Could fit 4 passengers and was moving at the speed of a manwalking at a normal pace. Its use was, besides, extremely dangerous, because there was a risk that thesteam boiler were to explode due to the high pressureIn 1784 William Murdoch built a steam carriage model and in 1801 Richard Trevithick drove a vehicle inCamborne (UK). In these early vehicles were developed innovations like the hand brake and wheel speeds.In 1815JosefBozek, built an engine-powered car withaceite.2WalterHancock,in 1838, Robert Davidsonbuiltanelectric locomotivethatreached 6kmper hour.Between 1832and 1839RobertAndersoninvented thefirst cardrivenbynon-rechargeableelectric cells.The Belgian Etienne Lenoir made work a car with an internal combustion engine around 1860, powered by coalgas.KarlBenzbuilt hisfirst modelin 1885 inMannheim.BenzpatentedtheJanuary 29, 1886and beganproducingin1888.Soon after,GottliebDaimlerand WilhelmMaybachin Stuttgartdesigned theirown carin 1889.The one whoinvented themodern automobilewas theGerman engineerCarlBenz.Benzindustrial enginesbegan buildingin 1883.By 1885, Benz, installed on a tricycle, a single cylinderengine, whichworked wonders, andledhimthroughouthis city.By 1886, Benz patented hiscar, becomingwho invented themodern automobile.
  • The power source or more exactly the heart of these machines is called engine.An engine or motor is a machinedesigned to convert energy into useful mechanical motion.But there are two important types of engineExternal combustion engine which was invented by Joseph Cugnot and the internal combustion engine developby Carl Benz but how does it work???Well an external combustion engine (EC engine) is a heat engine where an (internal) working fluid isheated by combustion in an external source, through the engine wall or a heat exchanger. The fluid then,by expanding and acting on the mechanism of the engine, produces motion and usable work.[1] The fluidis then cooled, compressed and reused (closed cycle), or (less commonly) dumped, and cool fluid pulledin (open cycle air engine).An ECE work in this wayThe internal combustion engine is an engine in which the combustion of a fuel (normally a fossil fuel) occurswith an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. Inan internal combustion engine, the expansion of the high-temperature and high-pressure gases is produced bycombustion apply direct force to some component of the engine. This force is applied typically to pistons,turbine blades, or a nozzle. This force moves the component over a distance, transforming chemical energy intouseful mechanical energy. The first commercially successful internal combustion engine was created by ÉtienneLenoir.[1]

  • The time was running and the car was changing and with these changes came new partsHenry Ford (July 30, 1863 – April 7, 1947) was an American industrialist, the founder of the Ford MotorCompany, and sponsor of the development of the assembly line technique of mass production. The introductionof the Model “T”automobile revolutionized transportation and American industry.
  • Has the record of one of the most famous cars in the world 1. Toyota Corolla 2. Ford - F series3. Volkswagen Golf4. Volkswagen Beetle5 Ford Model TWorlds Most Expensive Cars: 1. Bugatti Veyron Super Sports$2,400,000. This is by far the most expensive street legal car available on the market today (the base Veyron costs $1,700,000). It is the fastest accelerating car reaching 0-60 in 2.5 seconds. 431km/h The cheaper El Chevrolet Chevette The faster Thrust ssc 1149 kmh. brake the sound barer The smaller Peel P50 The heaviestand the biggestwith 12.804Tons Bagger 288The most luxurious.theSaleenPotential future car technologies include varied energy sources and materials, which are beingdeveloped in order to make automobiles more energy efficient with reduced regulated emissions. Carsare being developed in many different ways.With rising gas prices, the future of the automobile is now leaning towards fuel efficiency, energy-savers, hybrid vehicles, battery electric vehicles, and fuel-cell vehicles.
