2. A helicopter's rotor shaft has the hollow circular cross section shown as follows. The shaft is subjected to an axial load \( \mathrm{P}=34,000 \mathrm{~N} \) and a torque \( \mathrm{T}=600 \mathrm{~N}-\mathrm{m} \). Determine the principal stresses and the absolute maximum shear stress at a point \( \mathrm{p} \) on the outer surface of the shaft. Draw the Mohr's circle of the stress state at point \( P \).
