….pull it tight, and then add 3 feet to the length of the rope, how high above the earth, equally suspended, would the new rope be?

There are very closely 10,000,000 meters from the North Pole to the equator through Paris. So that's roughly 40,000,000 meters all around. We'll say that 3 feet is a meter, so we'll add one meter.
C = 2πr r = C/2π r1 = 40,000,000 / 2π = 6366197.72368 meters r2 = 40,000,001 / 2π = 6366197.88283 meters Uh...that doesn't make any sense... How can adding one meter of length add more than a decimeter to the radius? |

How can adding one meter of length add more than a decimeter to the radius? You’re solving for radius - shouldn’t you be solving for diameter since it’s supposed to be equally spaced? Or not? Where are the magnets? |

Holy crap people.
This is 5th grade math. Answer is 3'/(2pi), so basically 5.75". Circumference is D x pi. It's linear. So we don't need to know C or D to calculate incrementatity. For the equation to hold true, if you add 36" to circumference, you must add 36"/pi to diameter. That means the diameter of this imaginary rope circle is 11.5" larger. Since it's equally suspended, that would mean the 11.5" is split in 2, since the antipode would also have 5.75" of air between earth and rope. |

As others have proven, just shy of half a foot, if the elasticity of the rope is ignored. However, the logistics of it make this a practical impossibility, not to mention a trip hazard.

Static or dynamic rope?
|
|
|
|
|
Posted: 5/13/2022 9:14:45 PM EDT
The answer is 0 since the part of the rope that goes thru the hood would be cut and attached to a stolen car and the whole thing would be pulled out of place.

Since it would mean from above it could there could be many correct answers. The rope was also tight before the addition of 3' so who knows.

OP can't comprehend that gravity varies with location, let alone a fucking tape measure. It's not a gotcha question. It is a question to find out how you think. Do you guestimate based on scale and gut feeling. Or do you slap the simple math on the problem and come up with the basic and correct answer. It's one of my favorite "riddles", because I got it wrong, initially, even though I deal with math and geometry every day. My logical self said, "Well, you're only adding a very small amount of rope, percentage wise, so the rise would be infinitesimal. As others point out, the rise would be identical to the rise if you added 3 feet to your belt. Roughly 6 inches. Because of pi and geometry which is an awesome thing. |

Exactly. I'd call it "barely measurable". You would think so, wouldn't you? But, no. OP should have eliminated the physical reality of the thought experiment by discounting any actual elasticity of the rope, assume perfect roundness of the Earth, etc. Assume normal laws of geometry such as the definitions of radius, circumference, etc. |
