Q: The material in which large deformation is possible before rupture is termed as ______.
  • A. Elastic
  • B. Brittle
  • C. Plastic
  • D. Ductile
Correct Answer: Option D - Ductile materials– The materials that break after large deformations with significant warning before failure. These have long plastic range or more tensile strain upto rupture. Example– steel, reinforced concrete and some other metals etc. Brittle materials– The materials that break after small deformation without significant warning before failure example cast iron, concrete and natural stones.
