Document Summary
Iron and steel used for construction practices; definite size and shape; (ex: i-beam); standardized over the years (properties and microstructure) Copper and its alloys useful in infrastructure; high conductivity of electricity and heat (property that many other metals do not have); used in wires. Nickel, titanium, and their alloys expensive materials because they are not easily available; Silica (sio2), glasses and silicates very abundant. Cement and concrete most used material for infrastructure; Dark (black) gold crude oil (asphalt, greases, gases, oils, etc. ) Red gold blood (contains all the elements of life) We are composite of white and red golds. Input forces material specimen response: laws of rigid body mechanics. Newton"s first law every body continues in its state of rest or of uniform motion in a straight line unless it is acted on by a force. Newton"s second law force = mass * acceleration.
