70% to pass

Blocks and falls used as lifeboat gear must be designed with a minimum safety factor of _______________.

A 6, based on the maximum working load
B 8, based on the normal working load
C 4, based on the breaking strength
D 5, based on the maximum allowable stress
AI Explanation

The correct answer is A) 6, based on the maximum working load. According to the US Coast Guard regulations, blocks and falls used as lifeboat gear must be designed with a minimum safety factor of 6, based on the maximum working load. This is to ensure that the equipment can withstand at least 6 times the maximum expected load, providing a robust and reliable system for launching and recovering lifeboats. The other options are incorrect because they do not align with the specific Coast Guard requirement for a safety factor of 6 based on the maximum working load. Options B, C, and D reference different factors, such as normal working load, breaking strength, or maximum allowable stress, which are not the relevant criteria for this particular regulation.
