A groove is machined into the circumference of a steel shaft held in cantilever and supporting a bevel (miter) gear mating to an identical gear with an axis 90° to intersecting shaft axis. The normal force is known to be Fn = 8500 N and the tangential force is Ft = 5500 N. For a stress element located at point A on the diagram and assuming the shaft is rotating, determine the properties of the cyclic stress wave listed below, for one full revolution of the shaft. Include the stress concentration factors and use maximum distortional energy theory for stress analysis. a) min (minimum stress) b) gmax (maximum stress) c) Om (mean stress) d) σα (alternating stress/stress amplitude) e) σr (stress range) D = 60 mm Shaft diameter at base of notch d = 50 mm r = 6 mm Machined Surface Fn 200 mm 45° Point A Mating bevel gear Ft Into page 100 mm
