A component subjected to tensile stress in a mechanical device is monitored periodically for cracks by NDT. The NDT technique can only detect cracks (both surface and internal) which are larger than 1 mm. Keeping a 10% margin of safety, the maximum allowed tensile stress on the component will be _______ MPa (round off to the nearest integer). Given, fracture toughness KIC = 30 MPa m1/2 and assume crack geometry factor of unity.
