1) Density is measured in kilograms per cubic meter.
2) Most materials have a higher density than water and sink in water.
3) The density of the material is very important, especially in aviation.
4) Young's modulus is the ratio of the applied force to the elastic deformation of a given material.
5) The more rigid the metal, the less it deforms under load.
6) when the metal is stretched, it first flows, that is, it is plastically deformed.
7) Lead, copper, aluminum and gold are the most malleable metals.
8) Creep resistance is a very important property of materials used in aircraft engines.
