Mechanical Properties Of Solids

Question 1

State Hooke’s law

Answer 1

For a small deformation in a material, the extent of the deformation is directly proportional to the deforming force.

Question 2

Differentiate between brittle and ductile materials.

Answer 2

Ductile materials:
- Can withstand large amount of strain before breaking
- Have relatively small Young’s modulus
- Examples include steel and aluminium

Brittle Materials
- Breaks at the smallest strain
- Has a relatively large Young’s modulus.
- Examples include glass
