Final answer:
To calculate the factor of safety (n) for a quenched tempered 42CrMo4 (EN 10083) 45 mm diameter bar, we need to consider the stress states and the yield strength of the material.
Step-by-step explanation:
To calculate the factor of safety (n) for a quenched tempered 42CrMo4 (EN 10083) 45 mm diameter bar, we need to consider the stress states.
Factor of Safety (n) = Ultimate Tensile Strength / Allowable Stress
To calculate the allowable stress, we need to know the yield strength of the material.
Once we have the yield strength, we can calculate the ultimate tensile strength and then determine the factor of safety.
