6-10 A rotating shaft of 25-mm diameter is simply supported by bearing reaction forces
R, and R2. The shaft is loaded with a transverse load of 13 kN as shown in the
figure. The shaft is made from AISI 1045 hot-rolled steel. The surface has been
machined. Determine
(a) the minimum static factor of safety based on yielding.
(b) the endurance limit, adjusted as necessary with Marin factors.
(c) the minimum fatigue factor of safety based on achieving infinite life.
(d) If the fatigue factor of safety is less than 1 (hint: it should be for this problem), then
estimate the life of the part in number of rotations.
The plate of the figure is subjected to a bending moment with irregular cycles, which are
repeated. In the graphic one of this cycles is represented in terms of stress which appears in
each section whose height is h. The piece is made of ductile steel. Determine the number
of repetitions of the sequence which the piece can resist before the failure takes place due
to fatigue considering a reliability of 95 %.
