1.For cubic crystals, as values of the planar indices h, k, and l increase, does the distance between adjacent and parallel planes (i.e., the interplanar spacing) increase or decrease? Why?

2.The surface energy of a single crystal depends on crystallographic orientation. Does this surface energy increase or decrease with an increase in planar density? Why?

3.For a ternary system, three components are present; temperature is also a variable. What is the maximum number of phases that may be present for a ternary system, assuming that pressure is held constant?

4.A steel shaft with a diameter of 40mm and length of 1.1m transmits 60hp from an electric motor to a compressor. If the allowable shear stress is 50MPa and the allowable angle of twist is 1.5 degrees, what is the minimum allowable speed of rotation?
