The temperature inside a NASCAR V-8 engine can reach 2000 degrees Fahrenheit the pressure can reach 1500 psi, or more than 100 times the normal air pressure we feel around us every day. Some parts exposed to the worst of an engine's extreme heat use special metals to keep them from melting and fusing with another part of the engine. NASCAR rules 1)carburated V-8 with iron block 2) NASCAR also requires teams to use blocks, cylinders and intake manifolds made from castings of approved manufacturers 3) NASCAR places strict limits, for instance, on how engine cylinders are bored THANK YOU!
brick. Although it had first been used in antiquity, iron was the miracle material of the Industrial Revolution. The Greeks and Romans had used it to reinforce stone pediments and columns in their temples and iron links had been forged by the Chinese and used in suspension bridges. The successful smelting of iron with coke, rather than charcoal, by English ironmaster Abraham Darby in 1709 freed iron production from fuel shortage restrictions, made large castings possible, and facilitated creation of the arch ribs for the world's first iron bridge, built seventy years later. In 1754, Henry Cort of Southampton (England) built the first rolling mill, making possible the efficient shaping of bar iron; in 1784 he patented a puddling furnace by means of which the carbon content in cast iron could be reduced to produce malleable iron. These two milestones of metallurgy realized the potential of iron as a major building material
