What are the factors that can affect the Factor of safety selection?
The factor of safety is used in designing a machine component.
Prior to selecting the correct factor of safety certain points must be taken into consideration such as :
The properties of the material used for the machine and the changes in its intrinsic properties over the time period of service.
The accuracy and authenticity of test results to the actual machine parts.
The applied load reliability.
The limit of stresses (localized).
The loss of property and life in case of failures.
The limit of initial stresses at the time period of manufacture.
The extent to which the assumptions can be simplified.
The factor of safety also depends on numerous other considerations such as the material, the method of manufacturing, the various types of stress, the part shapes etc.
