Question

Please do as many as you can but don't only do just few qouestion. If you just know few questions like 3 or 4 of em, then leave them to someone else. If you will do more than 4 I will appreciate that. Explanation is not necessary I only need answers.

Thank you

16. For Ca2+ substituting for Li* in Li20, a lithium ( vacancy/offset ) would be created, and for every Ca2+ ion added, a single lithium ( boundary/vacancy ) is formed. 4 17. A three-point transverse bending test is conducted on a cylindrical specimen of aluminum oxide having a reported flexural strength of 300 MPa (43,500 psi). If the specimen radius is 5.0 mm (0.20 in.), the support point separation distance is 15.0 mm (0.61 in.), and the applied load is 7500 N, calculate the applied stress, in MPa, on the given specimen. Report the answer to 4 significant figures and in units of MPa. 18. Would you predict that the specimen in the previous problem will break, given the flexural strength of the material is 300 MPa? (Yes / No) 4

Explanation / Answer

16 : vacancy,vacancy

17 : appiled stress = 381.972

12 : ratio = 0.3941

13 : cordination number = 4

14 : tetrahedral

9 : softening,working,melting,strain,annealing

10 : microelectromechanical, systems
