When a rope bridge is built across a canyon (think Indiana Jones) how was the rope first put across to start the bridge?

Pulled across by using a smaller rope. The smaller rope is pulled across using a string. The string can be carried across most easily by being attached to an arrow or similar projectile and shot across.In some cases, it might be possible for a boat to carry the string or rope across the canyon by water and then pull it back up to the top of the canyon.

I have used the arrow method to hang a long rope swing from a high branch inaccessible by climbing. A monofilament fishing line on a spinning reel was attached to the arrow and shot up and over the branch. A mason’s twine string was pulled over the branch by the monofilament, and a sturdy rope was pulled over by the mason’s twine.

Scientists and engineers are contemplating a similar problem: "the construction of a tether 100,000 kilometers long stretching from earth to well beyond geostationary orbit", to be the first step in the construction of an elevator to space.

The hard way There's no trick to it. You carry the rope down the canyon, across, and up. Sometimes you'll do it with a lighter guide rope, then tie that rope to the rope you're going to use and pull it back across.

That way the support rope hasn't been subjected to the scraping and other abuse of being carried down. Or you can get that first guide rope across some other way (tied to an arrow, flung out of a catapult). That guide rope can be of a lighter material than the one you'll use to support the bridge, since the only thing it needs to support is the first support rope..

With a bow and arrow. A light twine is coiled and attached to a massive arrow in a way that the coil can release during flight, but the end is still attached to the arrow. The other end is obviously anchored to the near side.

Somebody on the other end retrieves the arrow and that end of the twine. This end of the twine is tied to heavier rope, and that rope is dragged across by the initial twine. It builds from there.

There are other methods, such as catapults, or walking miles up stream where the gorge is not so wide and deep, and walking the ropes down to where the rope bridge is needed. I hope this helps.

There are a number of possible ways I will specifically mention two possibilities which cover most cases. The easiest way is starting with one person on each side of the canyon - you weight the rope with a rock or something, throw it across to the other person who ties it off to whatever you're using to secure it, and repeat until you have a full bridge. Probably have some wood or something in there also.

This is by far the easier of the two ways that I'm going to mention. If you're doing it on your own, though, it's harder. You need to find somewhere along the canyon that has something on the other side that's fairly sturdy, tall, and skinny - trees are about optimal here.

You could also hammer in a pole and then trek around to the other side (though I would throw the rope across while here, which makes the next part unnecessary). You then weight the rope with another rock-like object and have to throw it across in such a fashion for it to wrap several times around the tree-like object you're using - enough that it can support your weight. Tie off the near end, go across, tie it better, and then go back and forth throwing ropes and tying it off in the same manner as method #1.It's going to be considerably more time consuming and probably more dangerous, but if you have only 1 person you don't really have a choice.

What?! You've never heard of the rope-pigeon?! What?!

You've never heard of the rope-pigeon?! In ancient times, people would attach a long string to the rope and attach the other end of the string to a well trained rope-pigeon.At the right time, the pigeon would be released and would fly across the canyon into the waiting arms of a bridge builder. By the way, tradition tells us that a large percentage of foul language in our lexicons originated from these bridge builders as the string inevitably broke on the sharp edges of numerous rocks when they went to pull the rope across the canyon.

As technology advanced, these rope-pigeons found themselves without jobs..

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
