Here is a list of engineering materials:

$\backslash$table$[[$AISiC$,$CFRP$,$Grey cast iron,Medium carbon steel$],[$Phenolic resin,Polyamides,Polyester,Reinforced concrete$],[$Silica glass,Titanium alloy,Tungsten carbide,Zirconia$]]$

$($a$)$ Group the materials into the four main categories: metals, composites, polymers, ceramics, making clear the meaning of abbreviations in the list.

$($b$)$ Describe the common properties and characteristics associated with materials in each category.

$($c$)$ Choose one of the materials from each category $($metal$,$ composite, polymer, ceramic$).$

For each of the four materials you have chosen, select an engineering application and describe how the properties of the material make it suitable for that application.
