What is a Factor of Safety?

A Factor of Safety (FoS) is a measure of the amount of extra strength designed into a structure to withstand stress beyond the expected levels, ensuring an increased level of safety.

Example Calculation

Let's consider an example:

Using the formula to calculate the Factor of Safety:

\[ \text{FoS} = \frac{500}{250} = 2 \]

This means that the Factor of Safety (FoS) is 2.
