- Properties Of Materials
- Strength
- Strength is the ability to withstand forces without breaking
- Tensile strength-- resists pulling forces
- Compressive strength resists squashing forces
- Hardness
- This it the abiltity to withstand scratching, rubbing and denting
- Its very important for tools that cut out, like files and drills
- Toughness
- If a matrial is tough it is hard to break or snap- the material changes shape instead
- Armour and bulletproof vests need to be tough
- If a matrial is tough it is hard to break or snap- the material changes shape instead
- Strenght to weight ratio
- Materials that are strong but don't weigh much have a good (high) strength to weight ratio
- Plasticity
- If a material can change shape permanently without snapping or breaking the material has good plastic equalities
- This could mean that the material is malleable or ductlie
- Impact resistance
- This it the ability to withstand sudden forces without cracking
- Chemaical resistance
- If a material can come into contact with a chemical and not degrade (break down) its said to be resistant to the chemical
- Flexibilty
- Flexible materials can bend but don't necessarily return to their normal shape
- Strength
