Factor of Safety

Factor of safety, abbreviated as FS, also called safety factor, a dimensionless number, is the ability of a system's structural capacity to be usable beyond it's expected or acrual loads.

 

factor of safety formula

\(\large{ FS = \frac {UTS}{R}  }\)

Where:

\(\large{ FS }\) = factor of safety

\(\large{ R }\) = applied stress

\(\large{ UTS }\) = ultimate tensile stress
