Materials+and+Impact

=Materials and Impact= Steel has been a big part of cars ever since the start of the history of cars. Body, the largest part, consisted mostly of steel, which means a large part of the car is steel. In the earlier times, the only part that was not made of steel was the wheels, which were made of wood. The tires of the cars now are made of rubber, so rubber is a new material for making a car. Cars in the past had no windscreen, while cars nowadays do for protection from the weather outside. The addition of the windscreen means that glass is also needed for the production of a car. Really expensive cars now have carbon fiber along with steel are included in the body of the car.  Ever since the discovery of steel, many tools and objects have been made out of it. It is malleable, meaning it can be made into many shapes to improve the efficiency of the tool. Steel is extremely strong, which means that it will not break easily, making it suitable for building the frame of objects (cars, trains, buildings, ships etc). Steel is also a very good conductor of heat and electricity, causing it to be often found in wires or kitchen appliances like pots and pans. Steel also lasts a long time, and is resistant to wear.These properties of steel have enabled technology and science to improve over time, and ensuring that the quality of products are better. Advantages of using steel for the body of the car would be that the car has a streamlined shape due to steel’s ability to bend for more efficiency. Steel will also protect the people inside and hold up the structure of the car due to its strength. The car will also be able to run for a long time due to steel’s durability. A disadvantage would be the vehicle might overheat, due to the fact that steel is a good conductor of heat Steel is good for the environment as it replaces materials like plastic that harm the environment for objects like water bottles and cutlery. It can also be recycled and is sorted easily as it is magnetic. ==== Steel, a essential part of our modern world, has been used for many decades before we started using it for everyday things. The man (or woman) who first fused coal and iron together to create steel, has long since been dead and lost in the many creases and folds throughout history, though it has been speculated that that person may have been from India, where supposedly Caesar arrived and was given a sword far better than his bronze one, it was strong, light and "un-tarnishable". ====

Steel is a alloy, meaning it is not naturally found and is a fusion of two or more compounds. Steel, as before noted, is a combination of coal (for Carbon) and iron (Fe).
==== Yet again as said earlier, steel was forged in India, or at least the secret of it was unlocked, there have been pieces of steel that pre-date the Indian smitheries in Anatolia dating back to about 4,000 years ago, but there are VERY few of these and where not produced largely until the code was cracked in India. Soon after India, the Chinese, Romans, East Africans and Spanish (Iberian peninsula) soon exploded with steel work. ====

The chemical formula of steel is Fe3C. So there are 3 iron atoms and 1 carbon atom in one steel compound. Iron is the positively charged atom and carbon is the negatively charged atom. Steel is a very strong metal that consists of iron and coal. In the mid-19th century, steel became a very cheap mass produced material. Today it is one of the most common materials in the world. More than 1.3 billion tons of steel are produced annually. Steel is a very strong metal, which makes it a great material to use for a car. Steel also looks nice on cars because it is silver and shiny. A bad thing about steel is that it is much heavier than plastic.
