Computational analysis has determined that a particular design of glass ceramic component has a maximum allowable tensile stress of 21 MPa Your development team has suggested that a specific grade of Wollastonite with a Youngs Modulus of 87 GPa and a specific surface energy of 0.07 J/m2 may be suitable. What would be the maximum allowable size of any internal pores or defects in the glass ceramic component? (This question has only one correct answer) O a. 17.58 um O b. 9.30 mm O c. 17.58 mm O d. 9.30 m O e. 8.79 um O f. 18.59 um O g. 8.79 mm
