Answer:
The maximum length of a surface flaw is 8.24 μm
8.24 μm
Explanation:
Given that:
The modulus of elasticity E = 69 GPa
The specific surface energy
= 0.3 J/m²
The length of the surface flaw "a" = ??
From the theory of the brittle fracture;

Making a the subject of the formula; we have:


a = 8.24 × 10⁻⁶ m
a = 8.24 μm
Thus; the maximum length of a surface flaw is 8.24 μm
