Thin rope!

We have been discussing on our team how a thin rope will be attached on the air ship. With a thick rope its the knot that keeps it from sliding through the two tabs with the pin through it. If you use a thin rope, do you have to make a really big knot? Or can you make a loop and hook it to something? Anybody out there know? Thanks in advance!

Re: Thin rope!

You are required to have a retaining feature greater than 1 inch in your rope.

Re: Thin rope!

Take a look at the monkeys fist knot. It's pretty large and depending on the number of windings you do, can be as large as you'd like. Also they look really cool!

So if using a thin rope, like 1/8 or 1/4" then you must make enough knots to be greater than 1"? You cannot make a loop to hook it on the airship?

Re: Thin rope!

It looks like a Slot that the knot sits in, so if you have a thin rope, with a thin knot, it will slip through.

Re: Thin rope!

Just realized those things are huge. Some shaped like that would work. Maybe a disc swing could be used as the top anchor? Or would that be too big?

Yes if the larger-than-1-inch retaining feature must be part of the ROPE, then I guess a knot it is.

It is not made of non-metallic, woven fibers, so it is not legal to be a part of the rope.

Re: Thin rope!

We're looking at a .301" diameter rope a that should spool very nicely, but I'm afraid of looking back and thinking we could've done more.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

The image above is a three-strand monkey's fist in 3/8" braided polyester rope. Knot diameter ~2.3 inch.

Rep points to the first student who ties one, measures the length of rope required between the two taped points, and posts a correct result (+/- 30 mm).
