What are the three factors that affect rope stretch?

The three factors that affect rope stretch are elongation, constructional stretch, and elastic stretch. Understanding these factors is essential when assessing the behavior of a rope under load.

Elongation refers to the total increase in length of a rope under a specific load. It's determined by the material properties of the rope, which influence how much the rope will stretch when tension is applied.

Constructional stretch is the elongation that occurs due to the way the rope is constructed. It accounts for the movement of fibers and strands within the rope itself as they realign when under load. This type of stretch is inherent to the structure of the rope and varies based on the materials and fabrication techniques used.

Elastic stretch represents the reversible deformation of the rope caused by load. It is the stretch that occurs when the rope is loaded and returns to its original length once the load is removed. This characteristic is crucial for determining how safely a rope can be used in applications where dynamic loads are expected.

Recognizing these factors helps in selecting the right rope for specific applications, ensuring performance stability and safety. The other options mentioned do not encompass the physical properties and behaviors of rope relevant to stretch dynamics, making them less applicable in this context.
