What is the main reason for selecting specific engineering materials for construction?

• Color of the material

• Cost-effectiveness

• Material availability

• Material properties matching the application requirements

What factors influence the choice of engineering material?

• Only the cost

• Color and texture

• Mechanical properties, cost, availability, and environmental impact

• The recommendation of the designer

What is a common form of degradation of engineering materials?

• Improvement of mechanical properties over time

• Corrosion

• Becoming more malleable

• Increase in electrical conductivity

Why are non-ferrous metals often selected over ferrous metals in certain applications?

• They are always cheaper

• They are heavier, which is often desirable

• They generally have higher corrosion resistance

• They are easier to dispose of
