Question

Need help on this

You have been asked to draw up a specification for a ceramic cladding tile that is likely to experience tensile stresses of 69 MPa
during its installation and service lifetime.
If the ceramic has a specific surface energy of 0.26 J/m2 and its Youngs Modulus is 86 GPa what would be the maximum length of
an internal flaw that would not result in fracture of the tile?
(This question has only one correct answer)
a. 2.99 mm
O b. 5.98 µm
Ο c6.33 μη
O d. 3.16 mm
e. 3.16 um
O f. 5.98 mm
g. 2.99 μm
