Solve A,B and C (Only solution, No need for explanation)

(a) Derive linear density expressions for FCC[100] and [111] directions in terms of the atomic radius R. Compute and compare linear density values for these same two directions for copper (Cu). The atomic radius for copper is 0.128nm. (b) Derive the planar density expression for the HCP (0001) plane in terms of the atomic radius R. Compute the planar density value for this same plane for titanium (Ti). the atomic radius for titanium is 0.145nm (c) Derive planar density expressions for FCC (100) and (111) planes in terms of the atomic radius R. Compute and compare planar density values for these same two planes for nickel. the atomic radius for nickel is 0.125nm
