- You work for an off-shore wind turbine manufacturer and have been asked to review data from the support structure development team. The cost of the high strength steel currently used in the support structure has increased significantly in the last 12 months so the development team have manufactured some components to an identical design using a cheaper grade of structural steel. Company policy states that the critical tensile stress must be 30% more than the expected maximum in service stress of 420MPa. Given the information below, what is critical tensile stress of the cheaper grade of structural steel and would you recommend its use in the wind turbine support structure?
