A thin-walled cylindrical can with rigid end caps has a mean radius  and a wall thickness of  The can is pressurized and an additional tensile stress of 50 MPa is imposed along the axial direction as shown in the figure. Assume that the state of stress in the wall is uniform along its length. If the magnitudes of axial and circumferential components of stress in the can are equal, the pressure (in MPa) inside the can is __________ (correct to two decimal places).
