Question 2187 Deck General

The correct answer is C) diameter. The size of a wire rope is determined by its diameter, which is the overall thickness of the rope. This is the standard way of specifying the size of a wire rope, as it provides a clear and measurable dimension that can be used to select the appropriate rope for a particular application. The other answer choices are incorrect because they do not directly determine the size of the wire rope. The circumference (A) is derived from the diameter, the number of strands (B) and the number of wires in each strand (D) contribute to the overall construction of the rope, but do not define its size on their own.
