3. A hypothetical metal in Group II adopts a simple cubic unit cell structure. The X-ray diffraction and mechanical studies performed on the material give the following parameters; Poisson's ratio = 0.34, Eaverage = 3.75 GPa, Gyield = 410 MPa, Ots = 650 MPa a. When a stress is applied in the [211] direction, in which direction will the (001) plane start slipping? What is the minimum amount of stress to initiate plastic deformation? (Terss = 400 MPa) b. Predict the crystal structure of the ceramic material that is composed of aforementioned metal and fluorine atoms. Determine the atomic packing factor of the material. Ionic radius of metal ion is 114 pm and that of fluoride is 119 pm.
