At a point \(P\) in a body, Cartesian stress components are given by \(\sigma_{x x}=80 \mathrm{MPa}, \sigma_{y y}=-40\) \(\mathrm{MPa}, \sigma_{z z}=-40 \mathrm{MPa}\), and \(\tau_{x y}=\tau_{y z}=\tau_{z x}=80 \mathrm{MPa}\). Determine the traction vector and its normal component and shear component on a plane that is equally inclined to all three axes.
