Two lines sent out and pretensioned equally have the same length, same breaking strength and same directional load. However, one is made of wire (which has a full load elastic elongation of about 1.5 % of its length) and the other made of nylon (which has a full load elongation of about 30 % of its length). If a sudden gust of wind increases the load on the lines, this increased load will be shared as follows:
Wire takes 55 % of the extra load. Rope takes 45 % of the extra load
By the wire and rope equally
Wire takes 45 % of the extra load. Rope takes 55 % of the extra load
Wire takes 95 % of the extra load. Rope takes 5 % of the extra load
