WebNote: The hkl indices define a vector that starts at the origin and it perpendicular to the plane. Recall from your multi-variable or vector calculus class that the equation of a plane can be written as a!x + b!y + c!z = d, where the vector [abc] is perpendicular to the plane. In our case, a crystallographic plane can be written as h!a +k! b ... WebSHEAR STRENGTH Various methods are available for laboratory mea-surement of shear strength.
