A cylindrical tank subjected to internal pressure p is simultaneously compressed by an axial force F = 72 kN (see figure). The cylinder has diameter d = 100 mm and wall thickness t = 4 mm.

Calculate the maximum allowable internal pressure p_max
based upon an allowable shear stress in the wall of the tank of 60 MPa.
