Wire rope is designated by its diameter in which unit?

Wire rope is designated by its diameter in which unit?

• A. Inches
• B. Centimeters
• C. Feet
• D. Meters

Answer: (B)

The important idea here is that, in this context, wire rope diameter is specified using metric units. The course materials designate the rope’s thickness in centimeters, which keeps all related measurements and calculations—like compatibility with sheaves, drums, and load charts—in the same unit system. Using centimeters avoids the need to convert from inches and helps prevent reading or calculation errors in the field. That’s why the centimeter unit is the best choice for describing rope diameter in this material.
