Study Notes
Material Properties
- Rigidity: A property that indicates a material's ability to maintain shape and resist deformation when subjected to pressure.
- Brittleness: Characterizes materials that fracture or crumble easily when exposed to high stress or impact, lacking the ability to deform plastically.
- Flexibility: The capacity of a material to bend without breaking, allowing it to withstand forces without losing structural integrity.
- Elasticity: Refers to a material's ability to be stretched and return to its original shape once the applied stress is removed.
Examples and Applications
- Brittle Material: Common examples include glass and ceramics, which shatter under pressure rather than deform.
- Uses of Flexible Objects: Thin metal wires and plastic strings are often utilized in applications requiring flexibility, such as crafting, electrical wiring, and construction due to their ability to bend and conform to various shapes without breaking.
