🔍 Key Concepts

• Safety factor and what it compares (strength vs. expected load) • Difference between maximum working load, normal working load, breaking strength, and maximum allowable stress • Why lifesaving equipment like lifeboat blocks and falls are usually designed with a conservative (higher) safety factor

💭 Think About

• Ask yourself which description sounds like the way engineers usually define a safety factor for gear that regularly lifts people and boats: is it tied to working load or to ultimate breaking point? • Compare each option: which one combines a realistic reference load (what the gear is actually used at) with a safety margin big enough for lifesaving equipment? • Think about how "breaking strength" and "maximum allowable stress" are normally used in design codes—are they usually the direct basis for stating a safety factor on lifting gear used in emergencies?

✅ Before You Answer

• Make sure you understand that working load is what the gear is expected to carry in service, not the load at which it fails. • Verify that a proper safety factor means: (design strength) = (safety factor) × (reference load). Which option matches that idea? • Eliminate any option that bases the safety factor directly on breaking strength or stress in a way that does not reflect normal design practice for lifting/lifesaving gear.
