Question

1. define ductility.

Explanation:

Ductility is a property of a material (especially metals) that describes its ability to be drawn, stretched, or deformed plastically (without breaking) into a wire or thin sheet under tensile stress. It is often measured by the percentage elongation or the reduction in area of a material specimen before fracture. For example, metals like copper and gold are highly ductile, allowing them to be made into wires for electrical conduction or jewelry.

Answer:

Ductility is the property of a material (typically metals) to undergo plastic deformation (be stretched, drawn, or deformed without breaking) under tensile stress, often measured by percentage elongation or reduction in area before fracture, enabling it to be formed into wires or thin sheets (e.g., copper, gold are highly ductile).
