Historical Note on the 1.5 Factor of Safety for Aircraft Structures. Published Online:30 Aug 2012. Jul 22, 2014 ... Factors of Safety. For the tether system, the FAA proposes a minimum factor of safety of 3.0 for yield stress and 5.0 for ultimate stress. A study found that implants with conical connections showed lower stress than implants with internal hexagonal connections. The internal conical connection ... Oct 22, 2010 ... The factor of safety is applied to the stress, but we reduce the working or maximum stress by this factor, ie use a stress of 80/1.5 (80 divided by 1.5). Handling of chronometers, gun fire, motion of the ship at sea, changes of temperature, thickening of oil or the balance acquiring a magnetic polarity may cause ...
