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.

The structure of a carbon crystal and a silicon crystal are the
same. Why is the carbon crystal transparent and the silicon crystal
is not?
For a FCC crystal structure,
(a) Define three primitive vectors in the Cartesian Coordinates
in the most symmetrical form. The lattice constant of FCC is
‘a’.
(b) From the above primitive vectors in the direct lattice,
derive reciprocal primitive vectors in the Cartesian
Coordinates.
(c) What is the structure of the reciprocal lattice? What is the
length of the side of the cubic cell?
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.
