Calculate Factor of Safety (FOS) for static loads, fatigue failure, buckling and shear, with verdict gauge.
| Application | Recommended FOS | Reason |
|---|---|---|
| Aerospace / Aircraft | 1.2 – 1.5 | Well-known loads, high quality control |
| Automotive Components | 1.5 – 2.0 | Good load knowledge, mass production |
| Pressure Vessels | 2.0 – 4.0 | ASME code, risk of explosion |
| Structural Steel (Buildings) | 1.5 – 2.5 | IS 800 / AISC code |
| Lifting Equipment / Cranes | 3.0 – 5.0 | Human safety, IS 3938 |
| General Machine Design | 2.0 – 3.0 | Moderate uncertainty in loads |
| Cast Iron / Brittle Materials | 4.0 – 8.0 | No plastic deformation before fracture |
| Fatigue Loading | 1.3 – 2.5 | Goodman / Soderberg criterion |
The Safety Factor (FoS) is a critical design parameter in mechanical and structural engineering. It tells you how much stronger a component is compared to the load it must carry. This tool covers static, fatigue, and buckling safety factors, essential for design validation and compliance.
