A single crystal of a metal that has the FCC crystal structure is oriented such that a tensile stress is applied parallel to the [110] direction. The critical resolved shear stress for this material is 1.75 MPa.
1) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (1-10) direction.
2) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (10-1)direction.
3) Which of these two slip systems is the most favourably oriented (which system will see first plastic deformation)?

A single crystal of a metal is oriented for a tensile test such
that its slip plane normal makes an angle of 64.2° with the tensile
axis. Three possible slip directions make angles of 30°, 48°, and
78° with the same tensile axis.
(a) Which of these three slip directions is most favored?
(b) If plastic deformation begins at a tensile stress of 1.6 MPa
(232.1 psi), determine the critical resolved shear stress for this
metal

Consider a metal with an FCC crystal structure. The interplanar
spacing is known to be (2.0000x10^-1) nm. If the first-order angle
of diffraction (2*theta) is found to be (4.50x10^1) ° for the (311)
set of planes in this metal, what wavelength of monochromatic
x-radiation (in nm) must have been used for the diffraction? Use
scientific notation with 3 significant figures (X.YZ x 10^n). Note
that Avenue automatically enters x10, so you only need to enter
X.YZ and n.
