Question 2123Deck General70% to pass
Unless extremely flexible wire rope is used, the sheave diameter should always be as large as possible, but should never be less than _______________.
AI Explanation
The correct answer is B) 20 times the rope diameter.
The reason is that the sheave diameter should be at least 20 times the diameter of the wire rope, as per industry standards and best practices. This is to prevent excessive bending of the wire rope, which can lead to premature wear and failure. Using a sheave diameter that is too small compared to the rope diameter can cause the rope to bend too sharply, which can damage the rope's internal structure and reduce its strength and lifespan.
The other answer choices are incorrect because A) 2 times the rope diameter is too small, C) the rope diameter is also too small, and D) 10 times the rope diameter, while better than the first two, is still not the recommended minimum of 20 times the rope diameter.
