21. How are materials classified?
Materials can be classified into four main groups: metals, polymers, ceramics, and composites.
22. Give the opposites for: rigid, hard, weak, conductive.
conductive - Non-Conductive
weak - strong
rigid - soft\flexible
hard - malleable
23. What types of materials do you know? Give the examples.
Metals - Copper; iron; sodium; nickel
Polymers - polypropylene (PP); polyvinylchloride (PVC); polyethyleneterephthalate (PTE); teflon; polyester
Ceramics - porcelain; glass
Composites - Fiberglass; kevlar
24. What metals do you know? Name their properties.
sodium - malleable, soft, shiny, reacts with water, density less than 1 g\cub. cm. so it floats on a water surface
Copper - malleable, red
mercury - liqud, very heavy
Tungsten - Refractory; high-melting
25. What materials are flexible? Hard? Rigid?
lithium, Potassium are flexible
Tungsten is Hard
manganese; Chromium are Rigid
26. What is a composite? Give some examples.
A composite material is a combination of two materials with different physical and chemical properties.
Fiberglass - plastic that is combined with glass fibers
Plywood - a board of thin sheets of wood glued to each other with their fibers in transverse orientation, with synthetic resins, pressure and heat.
Concrete - is a combination of various substances: cement, sand, gravel or gravel and water.
27. How can you test glass? How can you test plastic?
28. What is an alloy? How can you test alloy? Give some examples of alloys
A metal alloy is a substance that combines more than one metal or mixes a metal with other non-metallic elements. In order to determine the chemical composition of an alloy a lot of chemical methods can be used e.g. Atomic Absorption Spectroscopy (AAS) or optical emission spectroscopy (OES).
brass - made of copper and zink
Duralumin - made of aluminum mostly and copper magnesium manganese
Nichrome - nickel and chromium
29. What is fiberglass? What are the properties of fiberglass?
Fiberglass is considered to be a strong, lightweight material that consists of thin fibers of glass that can be transformed into a woven layer or used as reinforcement. Fiberglass is versatile and has shown excellent strength, low weight, bendability and dimensional stability.
30. What is ferrous metal? What is nonferrous metal?
A ferrous metal is any metal that is primarily composed of iron and has magnetic properties.
non-ferrous metals are metals or alloys that do not contain iron in appreciable amounts.
31. How can you test rubber? Is it a pure material or a composite?
Rubber is a pure material that can be produced naturally from various plant sources or synthetically through a variety of chemical processes.
Rubber are usualy tested using various tension, compression, and adhesion tests.
32. Translate the following words: to break, to melt, conductive. How can you test metals?
to break - ломать, to melt - плавить, conductive - проводить (ток).
The most common tests performed on metal include chemical analysis, hardness test, tensile test, corrosion test.
33. Translate the following words: properties, flexible, conductive. What properties does steel have?
properties - свойства (хим. физимеские)
flexible - гибкий (можно согнуть и придать друугю форму)
conductive - см. 32
The physical properties of steel include: high strength, low weight, durability, hardness, and corrosive resistance, conductivity.

35. Name 3 rigid materials.
Diamond, boron nitride, tungsten carbide are the most rigid on the Earth.
36. What can you do with rubber? (Can you burn, crack, break etc. it?)
Rubber can be burnt, torn apart, folded
Plastic is a very versatile material that can be literally found everywhere. Some examples of its use: in packaging (PP, PE, PETF), in building and construction (styrofoam as an insulation), in consumer products (toothbrush, comb), in textiles (Polyester, nylon), in electrical industry (PVC).
38. What materials do you use in your project? Why?
I prefer to use some epoxy resin in my projects. It's a very versitile material. It can be used as a very strong adhesive or can be casted in molds to craft some small things, details or parts. The process of casting is very easy, not time-consuming and cheap.
