why use braided line for fishing?

Braided fishing line is thin, but is also durable and long-lasting as well. It can be useful if you'll be dealing with obstacles such as rocks and weeds when fishing. Because of the lower amount of stretch, braided fishing line will also have better sensitivity

disadvantages of braided fishing line

Braided line is generally more expensive than monofilament line. Braided line can put more stress on reel parts, rods and line guides causing premature wear and breakage. Braided line may not be the best choice when fishing clear water. If back lashed, braided line can sometimes be very difficult to untangle

If you had 100 miles of strong fishing line stretched out and attached one end to the trailer hitch of a car and started slowly inching forward, would the other end ever move, or would it break first?

Wouldn't that depend on the weight of the object you are trying to pull? I believe most fishing line is rated as "xx pound test" which determines the strength. If you are trying to pull a 2000 pound trailer I would guess you would need something similar to 2000 pound test fishing line.

In this case, 100 miles of fishing line. There's some factors that make me unsure about the result. You can't lift a 100lb weight with line that breaks at 50lbs max against gravity. But can you slide a hundred pound line without the constant pull of gravity, and when you've reduced the friction by leaving it as thin as possible?

But then I suppose gravity is still acting on the line, so there's that.

Btw, there is nothing at the end of the line. You're trying to pull a very long line with a vehicle moving very slowly.

My guess is it would break somewhere near the trailer hitch eventually, since stress has been on that part of the line the longest.

30lb test weighs about 1lb / mile so 100lbs of line for your 100 mile question. I suspect that the friction of the line lying on the ground would be more than the weight. A casual look at the chart and I don't think you would ever get a large enough line to do it since the line gets heavier as it gets stronger.

Could you do it in water? Maybe if it was floating line but I am not sure and don't feel like doing the engineering calculations.

It would obviously break close to the hitch since the closer you are to the hitch the more force is on the line.

as a thought experiment, you could declare there is no friction. In that case, it would be a matter of whether the weight of the line mattered, and how slow you had to go, maybe it would be real slow

I'm reminded of trying to explain what a thought experiment was to an old boss after we argued whether a lead balloon could float. He could not get off the idea that it was impractical, just couldn't understand what a thought experiment was. So he refused to believe a lead balloon could float if you filled one with the right parameters with hydrogen. I'm sure it could as a thought experiment, but probably never could actually be made

How did they keep beer cold in the Old West saloons?

Answer and Explanation: In the Old West, people did not always enjoy their beer cold, for their were no modern refrigerators. To keep beer cold, people would keep kegs of beer in caves and rock cellars, lined with harvested river ice. Sometimes, they would even use wet gunny sacks full of sawdust to cool beer, as well.

Hmm

Quote:

Sawdust is a bad conductor of heat. The air filled in the fine pores of saw dust is an insulator of heat. This air does not allow heat from outside to pass to the ice thereby preventing its melting.

Maybe sawdust cooling needs to be reintroduced. Certainly, hot enough around here to try it.

where comes the phrase from each according to ability, to each according to need?

"From each according to his ability, to each according to his needs" (German: Jeder nach seinen Fähigkeiten, jedem nach seinen Bedürfnissen) is a slogan popularised by Karl Marx in his 1875 Critique of the Gotha Programme. The principle refers to free access to and distribution of goods, capital and services

What is the difference between a Marxist and a communist?

Difference between Marxism and Communism & Their Comparisons
Marxism is a social, political, and economic theory originated from Karl Marx, focusing on the struggles between capitalists and the working class. Communism is based upon the ideas of common ownership and the absence of social classes, money and the state

What is Marxism Leninism in simple terms?

Marxism–Leninism holds that a two-stage communist revolution is needed to replace capitalism. A vanguard party, organized through democratic centralism, would seize power on behalf of the proletariat and establish a one-party socialist state, called the dictatorship of the proletariat
