Question

What is the definition of the modulus of toughness of a material?

I- The modulus of toughness is the ability of a material to absorb energy until it breaks.
II- The modulus of toughness is represented by the entire area under the stress-strain diagram.
III- The modulus of toughness is the density of energy of the material just before it breaks.
a) Only I is correct.
b) Only II is correct.
c) Only III is correct.
d) I and II are correct.
e) I, II, and III are correct.

Ed · Answer

A definição do módulo de tenacidade de um material é a alternativa I: a capacidade de um material de absorver energia até quebrar. A alternativa II está incorreta, pois se refere ao módulo de elasticidade, e a alternativa III também está incorreta, pois não existe um conceito de densidade de energia de um material antes de quebrar. Portanto, a resposta correta é a alternativa A) Somente I está correta.
