Interactive FAQ
What is the safety factor?
The safety factor is a multiplier used to account for uncertainties and ensure the structure has a sufficient margin of safety.
How do I interpret the results?
The results provide the hoop stress in Pascals (Pa). You can compare this value with the yield strength of the material to ensure the structure is safe.
