70% to passWhat is meant by the term toughness as it applies to a material?
AThe ability to resist penetration.
BThe ability to resist repeated application and release of force.
CThe ability to resist continuous tension.
DThe ability to resist continuous compression.
AI Explanation
The correct answer is B) The ability to resist repeated application and release of force. Toughness in materials science refers to the ability of a material to absorb energy and deform plastically without fracturing. This means that a tough material can withstand repeated impacts or cycles of loading and unloading without breaking. Answer B captures this definition of toughness, as it describes the material's ability to resist the repeated application and release of force. The other answer choices are incorrect because they describe different material properties - A) hardness, C) tensile strength, and D) compressive strength - which are related but distinct from toughness.
