What must rotation-resistant rope support in relation to the designated load?

The requirement for rotation-resistant rope is that it must support a designated load at a safety factor of 10 times the intended load. This means that if a rope is designated to support a specific weight, it should be capable of withstanding a load up to ten times that weight without failure.

This safety factor is crucial in rigging applications where the consequences of failure can be severe. The higher safety ratio accounts for various factors such as dynamic forces, wear and tear, and potential shock loads that can occur during usage. It ensures that the rope maintains its integrity and provides a sufficient margin of safety under operational conditions, enhancing the overall safety of the rigging system.

In contrast, other options may reflect safety factors relevant to different rigging equipment or less demanding applications, but they do not align with the specific standards required for rotation-resistant rope. The adoption of a 10-to-1 safety ratio is a widely accepted practice in the rigging industry to ensure safety and reliability when handling loads, making it the correct and most appropriate choice for this scenario.
