Question: A cylindrical pressure vessel with closed ends is being designed for an internal pressure of 1 0 MPa with a factor of safety of 1

A cylindrical pressure vessel with closed ends is being designed for an internal pressure of 10 MPa with a factor of safety of 1.7 against yielding. The yield stress of the steel is 284 MPa. If the diameter of the pressure vessel is 141 mm, what is the minimum required wall thickness in accordance with Tresca criterion? Give your answer in mm and to two decimal places.
