A rotating shaft of 25-mm diameter is simply supported by bearing reaction forces R and R. The shaft is loaded with a transverse load of 13 kN as shown in the figure.
A rotating shaft of 25-mm diameter is simply supported by bearing reaction forces R and R. 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.
