This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Factor of Safety - Factor of Safety is the ratio of maximum shear stress a material can withstand to the maximum shear stress it is subjected to.
Tensile Yield Strength - (Measured in Pascal) - Tensile Yield Strength is the maximum stress a material can withstand without permanent deformation, used in Principal Stress Theory to analyze material failure.

Define Factor of Safety?

The factor of safety (FoS) is a design parameter that provides a safety margin between the actual strength of a material or structure and the expected load it will experience. It is the ratio of the material's maximum strength to the actual applied load. A higher factor of safety indicates a greater margin for error, ensuring that the structure can withstand unforeseen loads or conditions without failing. It is commonly used in engineering to enhance the reliability and safety of designs, especially in critical applications.
