Is this a Safety Factor or sometimes referred to as a Factor of Safety

Margin of Failure is a slightly different way to express the Safety Factor. An example is the easiest way to clarify the difference:

Say that a simple beam has a 10 kip load applied, but the beam fails when the load is 23 kips (applied in exactly the same way).

The Safety Factor is: 23 kips / 10 kips = 2.3

The Margin of Failure is: (23 kips - 10 kips) / 10 kips = 1.3

Thxs SlideRuleEra, I haven't run across this term before and was unsure of what the author of the report I was reading was trying to convey.

Thanks again,
