I want to tell you about my best friend Vlada. We met Vlada at school, in the first grade and have been friends for 7 years. We have many common interests and therefore we are good friends. We went to dances together, and now we go to athletics. Vlada draws very beautifully. She has a younger brother and sister, Lesha and Vika. Vlada is a beautiful and slender blonde with dark green eyes. I like to be friends with Vlada.

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.
