circular cylinder

[logistic_guy]

A solid circular cylinder of \(\displaystyle 100\)-\(\displaystyle \text{mm}\) diameter is subjected to a bending moment \(\displaystyle M = 3.375 \ \text{kN} \cdot \text{m}\), an axial tensile force \(\displaystyle P = 90 \ \text{kN}\), and a twisting end couple \(\displaystyle T = 4.5 \ \text{kN} \cdot \text{m}\). Determine the stress deviator tensor.
