Factor of safety is the limit where the material starts showing signs of crack. It does not mean that the material is going to break at this point but it sags to limit where it shows signs of crack. Mostly it can also be termed as a starting point of crack propagation.It is required to provide the buffer strength for the given material without failure
Hence, It is defined as ratio of maximum or ultimate stress of the material it can withstand to the working stress which it is designed.
Factor of safety = Maximum stress/Working stress
