A prismatic bar is subjected to an axial force
that produces a tensile stress σ_θ
= 65 u MPa and a
shear stress τ_θ
= 23 u MPa on a certain inclined plane
(see figure). Determine the stresses acting on all faces
of a stress element oriented at θ = 30°, and show the
stresses on a sketch of the element.
