MECHANICAL PROPERTIES OF METALS
PROBLEM SOLUTIONS
6.1 This problem asks that we derive Equations (6.4a) and (6.4b), using mechanics of materials
principles. In Figure (a) below is shown a block element of material of cross-sectional area A that is
subjected to a tensile force P. Also represented is a plane that is oriented at an angle θ referenced
to the plane perpendicular to the tensile axis; the area of this plane is A = A/cos θ. In addition, the
forces normal and parallel to this plane are labeled as P and V, respectively. Furthermore, on the
left-hand side of this block element are shown force components that are tangential and
perpendicular to the inclined plane. In Figure (b) are shown the orientations of the applied stress σ,
the normal stress to this plane σ, as well as the shear stress τ taken parallel to this inclined plane.
In addition, two coordinate axis systems in represented in Figure (c): the primed x and y axes are
referenced to the inclined plane, whereas the unprimed x axis is taken parallel to the applied stress.
