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 87GPa and a specific surface energy of 0.07J/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) a. 17.58m b. 9.30mm c. 17.58mm d. 9.30m f. 18.59m g. 8.79mm
