So here's a question for ya boyscouts" You know those rope ladders? the kind with the wooden dowels that are used as stairs? Well, my question is, how could a grappling hook be affixed to a rope ladder so that the hook and its rope are thrown, but when you go to pull on the rope connected to the hook the slack between the two are synched together so that the ladder climbs up to the top of the hook? This way, the hook can be thrown great distances, affix itself to a roof, and the rope ladder would be pulled to the top of the building? I'm having trouble conceptualizing how this would work, its not exactly intuitive, nor is it something I've thought about a great deal (much like how I was bogged when trying to solve a rubicks cube based on written instructions) Advice would be tremendously appreciated.
