Forces are transmitted across the contact points in a wire rope. Wires tend to bend in between the contact points and they tend to nick and cut at the contact points. A computer method is discussed to determine the contact points in a wire rope. In a geometrically perfect wire rope with the wires laid as double-helices no contact point occurs. But in an actual rope, the geometry changes while laying and due to loading, thus permitting contacts at a number of points. The paper discusses such contact points. Some refinements of the basic model were considered and results presented.
