Safety factor definition

Safety factor means the ratio of the ultimate breaking strength of a member or piece of material or equip- ment to the actual working stress or safe load when in use.
Safety factor means the ratio of the available shear strength to the developed shear stress, or the ratio of the sum of the resisting forces to the sum of the loading or driving forces, as determined by accepted engineering practices.
Safety factor means the ratio obtained by dividing the breaking load of any piece of equipment by its safe working load.
