Title: Re: Experiment with Braided Line
Post by: JSS on September 24, 2020, 12:21:14 AM
What i am planning to do, is that im going to put one extremity of the line in one side of the lake, and the other part in the opposite margin 10 km away, just like a very straight line, 20 cm above the water level.

The reason this is not done is there is no material you can make a rope or cable out of that won't sag at that distance.  In fact, you can't stretch a line for very far at all before it starts to visibly sag no matter how expensive, strong or light.

Yes, 10,000m is going to sag. A lot!  :'(

It's been done. You are welcome to do it again!  Please take video / meticulous documentation!

Use a frozen lake, and measure the rope factoring in any elasticity if you keep the line taut.

Of course there are many other ways to skin this cat and, using buoyancy, the weight of the line "sagging" can be eliminated.

Under what context are you using buoyancy?  In the absence of gravity (which many claim is not real) there would be no pressure gradient, and if there were no pressure gradient, there would be no buoyancy.  Also, the effect of buoyancy does not eliminate the weight of anything - a 1000Kg boat weighs 1000Kg regardless of whether it is sat on a mud flat or floating on water.

Anyway, rather than use ropes, let's use light, and let's look at the "Frozen Lake Experiment" which is analogous to the cause:
