The tapered cantilever beam shown in the following figure is to have zero tractions on the bottom inclined surface. As discussed in the text (see Fig. 5.4 ), this may be specified by requiring T_x ⁽ⁿ⁾ = T⁽ⁿ⁾_y = 0. This condition can also be expressed in terms of components normal and tangential to the boundary surface as Tn⁽ⁿ⁾ = T_s⁽ⁿ⁾ = 0; thus implying that the normal and shearing stress on this surface should vanish. Show that these two specifications are equivalent.
