______ is the plasticity exhibited by a material under tension loading.

• A. Ductility
• B. Malleability
• C. Brittleness
• D. Hardness

Answer: (A)

Ductility is the plasticity exhibited by a material under tension loading. It describes how much a material can deform plastically before it fractures when pulled in tension. Ductile materials stretch and neck, showing substantial elongation before breaking, like copper or steel. Malleability, on the other hand, refers to plastic deformation under compressive forming (hammering into sheets), not tension. Brittleness is the opposite of ductility—little to no plastic deformation before fracture. Hardness measures resistance to indentation, not how much a material deforms under tensile load. Ductility is typically quantified by percent elongation or reduction in area in a tensile test.
