Strength Of Materials In Me - Study Mode

Explanation

Solution: The Factor of Safety (FoS) is a measure used in engineering to ensure that structures or components will perform safely under expected loads. It is defined as the ratio of the ultimate stress (the maximum stress a material can withstand before failure) to the working stress (the stress that the material is expected to endure during normal use). Factor of Safety Formula: The formula for Factor of Safety is: FoS = Ultimate Stress / Working Stress This ensures that the component or structure has enough strength to handle unexpected loads or conditions safely. Option B: Working stress to ultimate stress This option is incorrect as it represents the reciprocal of the Factor of Safety. Option C: Breaking stress to ultimate stress Breaking stress is essentially synonymous with ultimate stress, so this option does not correctly describe the Factor of Safety. Option D: Ultimate stress to breaking stress Since breaking stress and ultimate stress are the same, this option also does not describe the Factor of Safety correctly. Therefore, the correct answer is Option A: Ultimate stress to working stress .
