I am creating a horizontal zip line, in which a rider will be pulled with a rocket engine. Completely serious. One end of the wire will be secured to a tractor and the other to a large tree.
The zip line will be made from 12.5 gauge (2 mm) galvanized class 3 200 KPSI minimum tensile strength, high tensile smooth wire. It has a 680 kg (1500 lbs) minimum breaking load. I purchased the wire without the intention for it to support a rider. I would like to use this wire, purchasing a lower gauge (thicker wire) is not possible. Here is a link to the product I have. I attached a image of the product tag as well.
My question is, at a distance of 1200 ft (366 m), would the wire be able to support the load of a person 91 kg (200 lbs) on a pulley? If one wire length ins't enough, would two wires running parallel, each with separate pulleys (splitting the load: 91 kg / 2) be able to support the load?
I know so far:
-With a mass of 91 kg, the weight of the load would be 91 kg * 9.81 m/s (gravity), therefore the load would actually be 893 kg and require 893 kg / 2 = 446 kg at each end of the wire to keep tension on it. Here is a source https://www.physicsforums.com/threads/zip-wire-loading.244497/ and see also https://www.physicsforums.com/threads/calculating-horizontal-wire-cable-load.42371/
Any help would be greatly appreciated, thanks in advance! This is my first thread on Physics Forums :)
