Question 3568 Deck General

The correct answer is D) Resistance to corrosion. The 6x19 class of wire rope has a more compact and rigid construction compared to the 6x37 class. This makes the 6x19 class more resistant to corrosion, as there are fewer individual wires exposed to the elements. The tighter construction of the 6x19 class also provides better protection for the inner core of the rope, further enhancing its resistance to corrosion. In contrast, the more open 6x37 construction leaves more individual wires exposed, making it more susceptible to corrosion over time. The other options are incorrect because the 6x19 class does not necessarily have advantages over the 6x37 class in terms of resistance to elongation, holding power, or fatigue life. These properties are more dependent on the specific application and operating conditions of the wire rope.
