Engineering Materials and Properties Quiz

Engineering Materials and Properties Overview

• Engineering materials include metals, polymers, ceramics, and composites
• Metals are crystalline in structure, have good electrical and thermal conductivities, and form alloys when combined
• Examples of metals include copper, steel, aluminum, gold, brass, and bronze
• Metal applications include car bodies, tin cans, and conducting wires
• Polymers are light, have low electrical and thermal conductivity, and are used in various applications
• Ceramics are hard, brittle, and have high melting points; they are used in electrical insulators and thermal barriers
• Composites are made by combining two or more materials to create a new material with improved properties
• Atomic structure of solids and bonding of materials are key aspects of material properties
• Mechanical properties of materials include strength, stiffness, and ductility
• Minerals in the earth's crust are a major source of metals
• Minerals in certain places contain a high percentage of a particular metal
• Metals change geometrical shape permanently under external force
