Quick explanation
Understand the appropriate use of materials including polymers, composites, woods and metals based on their physical and working characteristics such as: • malleability • toughness • hardness • resistance to corrosion and degradation • thermal conductivity • electrical conductivity
- This point belongs to Materials and their applications, especially Materials and their applications.
- You need to be able to understand the appropriate use of materials including polymers, composites, woods and metals based on their physical and working characteristics such as: • malleability • toughness • hardness • resistance to corrosion and degradation • thermal conductivity • electrical conductivity.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Why it matters
This objective helps connect Materials and their applications to exam-style questions, flashcards, and revision notes for Materials and their applications.
Quick student answer
Which of the following materials is known for its high toughness?
Direct answer
Polycarbonate is known for its high toughness, making it resistant to impact and less likely to shatter compared to glass.
Key terms
- Corrosion Resistance: The ability of a material to withstand deterioration due to chemical reactions with its environment, particularly moisture and acids.
- Strength-to-Weight Ratio: A measure of the strength of a material relative to its weight, important for applications where minimizing weight is critical while maintaining structural integrity.
Common trap
Confusing toughness with hardness: Remember that toughness refers to a material's ability to absorb energy and deform without breaking, while hardness is a measure of a material's resistance to deformation.
