A pressurized cylindrical tank with flat ends is loaded by torques T and tensile forces P (see figure). The tank has a radius of r = 125 mm and wall thickness t = 6.5 mm. The internal pressure p = 7.25 MPa and the torque T = 850 Nm.

(a) What is the maximum permissible value of the forces P if the allowable tensile stress in the wall of the cylinder is 160 MPa?

(b) If forces P = 400 kN, what is the maximum acceptable internal pressure in the tank?
