A Thin-Walled Cylindrical Tank, Under Internal Pressure P, Is Com- $p_{\max }$

A thin-walled cylindrical tank, under internal pressure p, is com- pressed by a force F = 75 kN. Cylinder diameter is d = 90 mm and wall
Thickness t = 5.5 mm. Allowable normal stress is 110 MPa and allowable
Shear stress is 60 MPa. The maximum allowable internal pressure $p_{\max }$ is
Approximately: (A) $5 \mathrm{MPa}$
(B) $10 \mathrm{MPa}$
(C) $13 \mathrm{MPa}$
(D) $17 \mathrm{MPa}$
