Factor of Safety vs Material Strength / Ultimate Load

Vedi formula →

Formula

## Factor of Safety (FoS) The factor of safety expresses how much stronger a system is than it needs to be. ### Formula **FoS = Strength / Applied Load** A FoS of 1.0 means the member is at its exact limit. Values above 1.0 provide a safety margin. Typical minimum factors: buildings 1.5-2.0, bridges 2.0-3.0, aircraft 1.25-1.5, pressure vessels 3.0-4.0.

Esempio Risolto

A steel member with 250 MPa yield strength under 150 MPa stress.

  1. 01FoS = 250 / 150 = 1.67
  2. 02Utilization = 150 / 250 = 60%
  3. 03The member has a 67% safety margin above the working load.
