Factor of Safety Calculator

Factor of Safety Calculator

The factor of safety calculator is used to determine the level of safety and reliability of a design or structure by comparing the maximum load it can withstand to the expected or allowable load.


The formula for factor of safety is given as:

Factor of Safety = Ultimate Strength / Design Load

In this formula, the ultimate strength represents the maximum load or stress the design or structure can withstand before failure, and the design load is the expected or allowable load that the design is intended to support. A higher factor of safety indicates a more conservative and reliable design.


If the ultimate strength of a structure is determined to be 1000 units and the design load is 200 units, the factor of safety would be:

Factor of Safety = 1000 units / 200 units = 5
