(1) In shaft analysis, stress concentration factor for fatigue (Kf) is greater than that of the static loading (Kt). (2) Soderberg fatigue criterion is the most aggressive one in the fatigue analysis.
(3) The endurance limit of material obeys log-normal distribution.
(4) The preferred fit H7/s7 is a type of clearance fit.
(5) Key length is designed to provide desired factor of safety.
(6) Grades of bolt material are usually marked on its head.
(7) The advantage of Miner's method in fatigue analysis is taking into account the order of applied stresses.
