\( 24- \) A steel rod of diameter \( d=50 \mathrm{~mm}\left(\sigma_{\mathrm{yp}}=260 \mathrm{MPa}\right. \) ) supports an axial load \( \mathrm{P}=50 \mathrm{R} \) and vertical load \( \mathrm{R} \) acting at the end of an 0.8-m-long arm (bellow Figure). For point \( A \) and \( B \), obtain: (a) Stress tensor and its principal stresses. (b) Stress invariants. (c) Stress spherical and deviatoric tensors. (d) Stress invariants of stress deviatoric tensors. (e) The effective stress. (f) The shear and tangential octahedral stress. (g) The yield surface (function of R) for Von Mises and Tresca criterion.
