Question

The ability of the material to absorb energy before fracture is known as:

• A. Hardness
• B. Toughness
• C. Cold shortness
• D. Ductility

Answer 1

Answer:

B. Toughness

Toughness is the ability of a material to absorb energy up to fracture. Cold shortness is the loss in ductility of the material when worked below the recrystallization temperature. Ductility is the property of the material that enables it to be drawn out before rupture occurs. Hardness is the property of a material by which it resists the indentation on the surface.
