Mechanical Engineering > GATE 2017 SET-1 > Fatigue Design
A machine element has an ultimate strength (σu) of 600 N/mm2, and endurance limit (σen) of 250 N/mm2. The fatigue curve for the element on a log-log plot is shown below. If the element is to be designed for a finite life of 10000 cycles, the maximum amplitude of a completely reversed operating stress is ________ N/mm2.
