Question

The ability of a material to absorb energy in the elastic region is called-

• A. Ductility
• B. Resilience
• C. Toughness
• D. Hardness

Answer 1

Answer:

B. Resilience

Resilience is the ability of a material to absorb energy in the elastic region. It is the total strain energy stored in a given volume of a material within elastic limit. Ductility is the property of a material to be drawn into a wire with the application of tensile force. Toughness is the ability of a material to absorb energy before fracture takes place. Tough materials have the ability to bend, twist or stretch before failure takes place. Therefore, the correct answer is option 2 - Resilience.
