Factor of Safety Calculator

Formula

The formula to calculate the Factor of Safety is:

\[ \text{FoS} = \frac{\text{MS}}{\text{WS}} \]

Where:

\(\text{FoS}\) is the Factor of Safety
\(\text{MS}\) is the Maximum Stress
\(\text{WS}\) is the Working Stress

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:

Maximum Stress (MS): 500 N/m²
Working Stress (WS): 250 N/m²

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.
