A closed, thin-walled, cylindrical pressure vessel has a radius of 100 mm, a wall thickness of 4.0 mm. It contains randomly oriented semi-circular cracks of radius a, for which one can assume thatIKaσπ=. The internal pressure is 10 MPa, and there is a torque of 50 kN·m applied to it. A design engineer selects a material with a yield strength of 900 MPa, and a fracture toughness of 35 MPa√m to be used for the pressure vessel. Is this a qualified engineer? Justify your answer.
