Question

The energy per unit volume that can be absorbed by a material up to the point of fracture is known as:

• A. Resilience
• B. Endurance limit
• C. Toughness
• D. Modulus of rigidity

Hint:

To evaluate materials for impact resistance, focus on their toughness. Tough materials can absorb significant energy before failing.

Answer 1

The Correct Option is C

Toughness is defined as the energy per unit volume that a material can absorb before fracturing. It is a measure of a material's ability to withstand impact and stress without breaking. Toughness combines both strength and ductility and is an important property in materials used for structural applications. Resilience refers to the ability of a material to absorb energy without permanent deformation, and endurance limit refers to the maximum stress a material can withstand for an infinite number of loading cycles without failing.
