What is the linear density of a body centered cubic (BCC) unit cell along the cube edges? What is the linear density of a simple cubic (SC) unit cell along the face diagonals? What is the linear density of a face centered cubic (FCC) unit cell along the body diagonal?
Part A The plane famlies When beginning to think sbout calculating the maximum planar density, you will need to consider which plane to use. Selecting a plane can eeem daunting because there are an infinite number of planes in a cubic unit cell. However, when calculating the maximum pianar density for a plane with equal sized atoms, there are only a few families of planes that area important-thosee that pass through the corners of the unit cell. Sort all the...
How many atoms are in the following unit cells? Body centered cubic, face centered cubic (FCC), a hypothetical body centered/face centered cubic crystal, and a hypothetical diamond cubic structure with superimposed face centered cubic and body centered cubic atoms. Calculate the ratio of the packing factors for the following cases: simple cubic to face centered cubic. simple cubic to hypothetical face centered body centered cubic crystal (i.e. a face centered cubic with a similar atom placed in the center simple...
