What is created when a rope crosses over itself after a turn around an object?

When a rope crosses over itself after a turn around an object, it forms a nip. In rigging terminology, a nip refers to the point where the rope overlaps or binds itself due to being wrapped around an object. This can occur, for example, when tying off the load or securing the rope in a way that it tightly grips the object, which can lead to increased friction and pressure in the binding area.

This phenomenon is important to recognize because it can affect the integrity and effectiveness of the rope's ability to hold or lift a load. Understanding the implications of a nip can help in assessing safety and performance in lifting operations.

In contrast, a loop refers to a continuous circle made by the rope, a knot typically involves intertwining rope ends to create a secure fastening, and a hitch secures a rope to an object without tying it off. Identifying the differences between these terms is crucial for accurate communication and effective practices in rigging and hoisting.
