What is Factor of Safety?

The ratio of a structure's absolute strength (structural capability) to actual applied load; this is a measure of the reliability of a particular design. This is a calculated value, and is sometimes referred to, for the sake of clarity, as a realized factor of safety.

How to Calculate Factor of Safety?

Factor of Safety calculator uses Factor of Safety=Fracture Stress/Working Stress to calculate the Factor of Safety, Factor of safety is the ratio of ultimate stress to working stress. Factor of Safety and is denoted by F.O.S symbol.

How to calculate Factor of Safety using this online calculator? To use this online calculator for Factor of Safety, enter Fracture Stress (F.S) and Working Stress (W.S) and hit the calculate button. Here is how the Factor of Safety calculation can be explained with given input values -> 4 = 40/10.

FAQ

What is Factor of Safety?
Factor of safety is the ratio of ultimate stress to working stress and is represented as F.O.S=F.S/W.S or Factor of Safety=Fracture Stress/Working Stress. The fracture stress is the ultimate stress which material can bear and The Working Stress is the stress applied to the material.
How to calculate Factor of Safety?
Factor of safety is the ratio of ultimate stress to working stress is calculated using Factor of Safety=Fracture Stress/Working Stress. To calculate Factor of Safety, you need Fracture Stress (F.S) and Working Stress (W.S). With our tool, you need to enter the respective value for Fracture Stress and Working Stress and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
