PHYSICS 102 Lecture Notes - Tensile Testing, Intelligent Design, Covalent Bond
Document Summary
Stone age: began two million years ago, consists of natural materials, such as bones, clay, stones, woods and animal skins (for warmth). Bronze age: began five thousand years ago, first introduced in the far east, bronze is an alloy of copper and zinc, which can be cast or hammered, the first non-naturally growing, human-made material. Iron age: began three thousand years ago, by (unknowingly) adding carbon, they discovered steel, drastically improved basic design, and thus variety of (newfound) applications. Age of advanced materials: from the latter up to the present day, the sheer amount of materials available has grown exponentially, particularly over. Includes, ceramics, composites and polymers, and so on. the past hundred years. Investigation of the relationship between processing, structure, properties and performance. ". Microscopic level: comprised of grains, which are separated by boundaries, some can be large and small, some formed together and not. Gavin brown: viewable with the naked eye, in all aspects, not least weight.
